very strange heart sensation followed by adrenaline rush and fast heartbeat - very worried about this

Hi. I'm a 26 year old female, neither fat nor skinny, no smoking, only occasional alcohol use. Prior to what I'm about to describe, the only heart issues I had were: occasional flip-flopping feeling which knocked the wind out of me but only happened maybe a few times a year, and a sort of flip-flopping or difficulty beating when lying down on my left side (sometimes, not every time I lay this way - started around age 13).

Background: Three years ago something happened to me that I still haven't figured out - my heart started beating very fast and my BP went way up (so high that with every heartbeat I could see the tiny capillaries in my eyes as an overlay on my visual field). Paramedics couldn't bring them down so took me to "A&E" (aka the ER - I'm American but live in England). Absolutely nothing out of the ordinary happened (that I'm aware of) prior to this incident, except for insertion of Mirena IUD one week prior - I do still have it but now think I'll have it removed.

Thus began months of seemingly random 'attacks' during which I'd get varying combinations of tachycardia, high BP, tremors esp in left leg, lightheadedness, inability to fully inhale, feeling of not getting enough oxygen even if I could breathe properly, and the list goes on. I also had a terrible feeling of physical anxiety (churning stomach, agitation, etc) but with no mental anxiety as the apparent cause!!! Attacks could last minutes or hours and any combination of symptoms would happen. And in between attacks, my heart would regularly do many strange things - tachy, brady, irregular rhythm, extremely forceful beats, 'flip-flopping' feelings, etc.

I also sometimes experienced a sensation of the heart stopping and restarting - immediately after the restart I would feel a MASSIVE, uncomfortable surge of adrenaline and the heart would beat very fast for a little while. I could never figure out if I was getting an adrenaline surge that caused some odd heart behaviour that I felt before I actually felt the adrenaline, or what. Sometimes my heart would also start beating EXTREMELY fast from resting for no reason at all - it was literally immediate - this was also accompanied by an adrenaline rush but no preceding feeling of the heart stopping.

These incidents gradually decreased in frequency over time, along w/ the other symptoms, until after three years I was feeling mostly recovered from whatever got me. I viewed myself as not entirely back to normal, but almost there. UNTIL a couple of days ago, when I had another (random as always - I was just riding in the car reading, no stress) heart stoppage -> restart -> adrenaline event. This one was the second most severe one I've ever had and I thought I might die. Luckily the heart DID start pumping again so I'm still here. By now I'm pretty familiar with flip-floppings and extra-strong beats, etc, and this definitely feels very different and much more worrying. I am afraid that if it happens again, the heart might not start on its own.

I should also say that when I say it 'stops', I mean it seems to stop pumping blood...I get the impression there is still activity going on in the heart but that blood is not being circulated. Could it be ventricular fibrillation, or ...? Maybe adrenaline is not causing this, but rather my heart goes into an abnormal rhythm and my body releases adrenaline in an attempt to self-shock into proper rhythm?

During the most severe incident in '06 or '07, my colleagues said I turned "white as a sheet" while it was happening. That time, I was clawing at my chest (reflex reaction, I didn't actually think that would help) and thinking "please start please start please start", knowing I'd die if it didn't. That time, it felt like the heart was quivering/fluttering but not pumping. All other times including the one a couple of days ago, it has sort of felt like the heart is contracting in extreme slow motion, or having some sort of muscle cramp.  

I cannot figure this out and would welcome any insight anyone has to offer. After it all began in 06, I had a stress test (slightly above avg exercise tolerance), echo (normal), stress echo (normal) and many ECGs. The cardio said my heart was perfectly healthy. No evidence of MVP (which I thought I might have). He said the only thing to remark on was that the heart was smallish, but not abnormally so.

My GP diagnosed me w/ 'anxiety attacks' w/out finding it necessary to order any physical testing whatsoever. (The above cardio is a friend of my parents who saw me while I was on vacation in the US). GP put me on citalopram which I went along w/ just to be cooperative, and propranolol to help regulate what he viewed as anxiety-induced tachy. Did not seem to find it significant that symptoms did not occur during periods of actual mental anxiety. Said it might be pheochromocytoma, but that he wouldn't bother testing as that's so rare. Ashamed to say I didn't and still haven't actually demanded said testing.

All ECGs were normal except once at A&E when they caught random very hard beats interspersed w/ regular beats - v. hard beats could be seen as an extra-long downward spike on the readout. Of their own volition (as opposed to at my request), A&E sent this to a cardio (different one) who didn't bother to look at it and just told me not to worry. Thanks, buddy! So, not really knowing how to interpret these readouts, I still don't know if that was significant.

I'm currently seeing a neurologist for delayed sleep phase syndrome. After hearing all this, he very kindly volunteered to arrange for me to use the clinic's Holter monitor; he'll then send the tape to a cardiologist. Not sure when this will happen, though, as it's the NHS (meaning things do not tend to happen promptly).

At the time of the latest incident, I was on amoxicillin but no other meds continuously, although I have been taking lansoprazole at night only, for a week and a half to two weeks. A few days prior to the incident, I had taken myself off of the pramipexole that I'd been on for a week, as I was having trouble swallowing (for which the amoxicillin and lanso were prescribed - possible sinus/throat infection or gastric reflux - doc and I wanted to attack on both fronts in order to avoid the return of the laryngospams I'd had during recent respiratory infection).

Thanks in advance to anyone who might be able to help...

Oddly enough, I found this while searching what an adrenaline rush feels like, and I'm so glad I did as it sounds like what I have been experiencing lately.  Brief history, I have had palpitations for a few years now, and after some research and realizing it was most likely nothing to worry about, I was able to remain calm when it happened, and experienced nothing more than a strong heartbeat feeling in my throat that would cause me to have to cough.  I usually am laying down when this occurs, but not always.  Sometimes it seems triggered by bringing my chin to my chest which may be vagus nerve related (?).  More recently, I have had a similar type of heartbeat, but slightly different, enough to cause me alarm.  I too feel as if the heart has stopped.  This is followed by a cold tingling feeling in my arms and legs and the need to get up an move (this feeling is why I was researching adrenaline rush).  A few moments later and I feel the heart beating again but at a high rate.  This causes me great relief as I know I'm not going to die!  I am then able calm down, but still feel panicky and worried that is going to happen again.  The first time, I tried to locate my pulse but haven't done so since since it just causes greater panic.  I don't know if the 'rush' creates the panic, or the other way around.  I should also note that I have self diagnosed benign fasciculation syndrome/peripheral nerve hyperactivity which has been on and off for about 10 years.  I have been particularly twitchy for the last few months.  I also have anxiety, but have never had a panic attack, and it is controlled with meds.  I'm wondering if anyone else has BFS, because there are a lot of strange symptoms that seem to go along with it, and I'm wondering if this is just another one of them.

I read your original note with great interest.  I had the exact same symptoms earlier this year for a few months.  I would feel a kind of sinking feeling in my chest followed by a few very intense heart beats.  Then an INTENSE rush of blood would go up into my head and down my arms.  Some times it would happen repeatedly a few times.  Sometimes it would be several times a day, and then not for a few days.  It tended to happen when I lied down, leaned back or after I ate. There was no emotional component of anxiety or panic. It was not painful, but was very disturbing.  My body was telling me that there was something very wrong.

I went to multiple doctors.  GP, endocrinologist, internist.  All were dismissive.  They did not really examine me, or delve more deeply into my symptoms.  two of them suggested I see a psychiatrist, noting anxiety, depression, or mania as potential diagnoses.  I did see a psychiatrist who said there was nothing wrong with me mentally, but that I was sick and obviously frustrated.  Finally, after being a good patient and taking anxiety meds and antidepressants (even though I told them that I was neither anxious or depressed) my problem was solved.  One morning I woke up with terrible abdominal pain.  To make a long story short, I had a bowel obstruction surgically repaired, and after that the symptoms all waned away and stopped in about 3 or 4 weeks.  My diagnosis was that of an internal hernia, where the bowel gets intermittently partially abstracted and pinched off in some narrow opening in the abdomen.  I believe the adrenalin rushes were due to special nerves called sympathetic fibbers that line the bowels getting stretched or compressed.  They secrete adrenalin, and I believe they were being set off and causing abnormal signals to other parts of my body (e.g.. heart).

One thing I am brutally aware of now after being a patient, is that women's unusual or difficult to explain symptoms tend to be automatically explained off as anxiety.  I doubt that a male physician presenting in the ER with my symptoms would have been jerked off and sent to a psychiatrist like I was.  I actually told this to the ER doctor because I was getting really frustrated and mad, and he essentially told me that I was hostile and paranoid. Can you imagine what that felt like?

I am a doctor (family practice and maternity).  This is the advice I will give you.  IF YOU HAVE SOMETHING GOING ON AND YOU FEEL IT IS ABNORMAL, IT PROBABLY IS.  DO NOT LET YOUR DOCS IGNORE YOU. Take this note to your doc and discuss it with him.

In retrospect, I had hints of my bowel problems.  I had ongoing bloating and abdominal distension on and off for 1.5 years.  I had a decreased appetite, I had vague discomfort with eating.  If you have any of these sorts of symptoms too, but are ignoring them because the heart palpitations and head rushes are more intense, them take this to your doc and discuss it.  You may have what I had and it is treatable.  Best of luck.  DocKa

there are a couple of things i like to mention that may help you friends.

1. things we are experiencing , are not fatal. its a problem with heart signals and even in its very most severity for a healthy heart usually dosen't end up killing anyone.
let me tell you something about arrhythmia , arrhythmia that kill people are usually caused by heart attacks , obesity , cardiological problems , old age and bad genes. so please do a check up on your general health and heart.. if you didn't have the risk factors then the chance of you dying because of this is actually lowest possible.

this is important. cause when people experience these , they develop death phobia and that make this happen more and with more severity and ruin life quality as well.

2. I seen many of you keep testing your heart. stop doing the same thing over and over again. if you had holter tests , an echo and stress echo and 2-3 ECG then move on. a lot of other things can cause this but the heart itself. neurological problems , Anexity , drugs side effects even even gastritis and acid reflux

3. use a pulse oximeter , its a device that shows your heart beat per minute and your blood oxygen. but most importantly your pulse graph. wear it. and wait for next attack to happen. if your heart skip a beat then the graph will drop to zero. and if your blood oxygen started to drop as well then you know you have a heart condition. if none of these happened then you obviously are stressing yourself over nothing life threatening.

4. the heart beat raise and palpitation most of you develop after a heart skipped beat is adrenaline side effects not a heart condition. the body goes into a adrenaline shock. it suddenly faces a near death experience(or so you make it think unwantedly) and your heart pulse goes up at once. and you get a pounding heart that you can feel it.

5. Magnesium supplements really do miracle about this problem. in addition to this please try beta blockers pay attention beta blockers lose most of their efficiency if you take them after the attack. so its better to take them daily and on a regular basis to avoid the condition although it can help to treat it as well sometimes.

6. please sleep well. try to sleep.. do whatever it takes to sleep. bad sleep make this stuff happening 100x more than other times.

7. Oversensitivity about this will ruin your life and get you in more trouble , at the end worrying all the time for this doesn't immune you against it possible bitter ends. so let it go.dont over think it it will lead to over sensitivity and that will ruin just everything. do a full scale of check up. take special care with supplements and anti stress exercises and sleep enough and i assure you it will work better that putting even more pressure on your heart by over-thinking and lots of stress.

Here is my story.  I write this in a hotel room in Johannesburg, South Africa.  I am 40 yrs old and the CEO of a listed company.  Today, for no rhyme or reason on the plane I started to feel dizzy, my pulse rate went up, missed a few beats and pretty much raced for the rest of the day.  I popped a beta blocker which brought it down to normal as I cannot stand the feeling. As my heart raced throughout the day I became more and more panicked - arms and legs were tingling, felt dizzy etc.  This lasted the whole afternoon.

In 2005 I had a random episode of atrial fibrillation which lasted 12 hours and self corrected.  Had all the tests done and everything was fine and they advised that it was a random event.  Since then I feel every ectopic beat I get and when I get them, I still panic which sends the heart racing.  I have had multiple echo's, EKG's, stress tests etc and am always told my heart is in great shape - in fact, I had one as recently as a month ago.  

You would think given all the tests I have had, especially considering I have just had one, that when a random event of a racing heart strikes I should be able to deal with it - I am ashamed to say I still struggle deeply.  People have real problems, heart disease, cancer, epilepsy etc and here am I freaking out over something I have been told by experts is fine - why is that?

Here is why

Due to the randomness of these PVC's etc we never know when they are going to strike - we them find ourselves constantly waiting for the next one which puts you in a constant anxious state which results in more PVC's!  All we want is to not have them - they go away for a while, we think we are done with them and then they strike!  What I battle to deal with is the dissapointment of admitting that they are not gone for good and I have to deal with them again (sometimes I go for months without any - think I am clear and then WHAM!)

It is the vulnerability that I cannot stand, it is the constant guessing that I cannot stand, it is the pulse checking, the no coffee rule, the no red wine rule, the no big meal rule etc etc - we must (speaking for myself) be seriously boring people to have around.

I have taken the following decision - no longer will they get to me.  This is my Achilles heal and I am blessed to have it rather than something serious.  God has given us finite time on this earth and there is no point moping around waiting for the next jolt and not enjoying life - as it says in Mathew - worry cannot add one second to our lives - our time is our time so really, what are we worrying for - it will not change a thing!!!  And besides, these palpitations are benign!!!

What has helped me reduce them is;

Low carbs
Low caffene
No red wine - which *****!
Reduce sugar
Try and reduce stress
Exercise

All of the above are good for us anyway so we  may as well just suck it up and do it.  Magnesium supplements help me massively.

Lastly, carry a beta blocker as a crutch - if the pulse goes mad, pop one and just keep on trucking!

I hope this helps someone out there as I have dealt with this for 10 years, am still around and still coming to terms with them

Good luck, Gold bless
