supraventricular tachycardia

So for about a week I been feeling what I thought was a PAC's and still could be I guess..
I had a 24 hour heart monitor on that I returned yesterday.
I woke up to my phone ringing and the nurse from my regular physician told me the results.
She said, we got the results back and it looked like you have some SVT runs on your monitor, the Dr would like
you to have a Echo stress test and follow up with a cardiologist.

WTF WTF WTF is going on, those were my thoughts and it shot me into panic....
I had no idea what SVT was so I thought immediately I was gonna die soon.
I found out its supraventricular tachycardia and that I had a total of 160 beats on my 24 hour monitor, and one run of 16 beats.
Not sure if that is a lot or pretty normal for SVT, I was told its benign condition and there is up to
3 million cases a year and it is not LIFE THREATENING.

If this is what I have been feeling its very fast and only last 3-4 seconds usually but happens quite frequently.
Can SVT be that quit onset and off?

My Dr gave me some beta blockers to take, I have not taken them yet. 50mg of toprol (metoprolol) to take one
time daily.
I'm already taking blood pressure meds but he said to take both...WTF won't that make my BP way to low.
My normal reading is 120/65 pulse usually 59-65.
If I remember correctly my pac count was around 100 and my pvc was around 20.

All this is a lot to take in and I'm pretty scared at this point.
So here is my questions.

Who has SVT (PSVT) and how long have you had it?
Did you get ablation?
Have you tried beta blockers for it?
Did it work? How do they work?
Can I exercise with SVT?
Why did the Dr. call me so fast if its not dangerous?
Why did they set me up to have a echo stress test?
Should I be this worried?

Sorry for all this and thanks a ton for all the help, this board has already helped me a ton.

Usually the way they tell if it is an svt or simply sinus tachycardia is if there is a wave missing.  In regular sinus tachycardia all the proper waves are there it is just a fast beat.  Sometimes svt can mimic sinus tachycardia so doctors will usually diagnose it if they see the fast rate start and/or stop in one beat.  That is usually the best way to tell.  If it was just a tech reading it is possible that the cardiologist will change the diagnosis but for your knowledge 1% means only 1% of your beats were associated with the issue so very minimal.  For you it was less than 1% which could mean only a couple of beats.  

Also for your peace of mind my cardiologist said it is unheard of for someone to drop dead from anything in the atria.  That doesn't mean it can't happen but odds are very slim that it will.  Even afib is not an immediate threat.  The biggest threat with afib is when a person goes back into normal sinus rhythm there is a chance they may throw a clot and have issues from that.  Atrial issues generally are long term issues that threaten heart failure but usually only after an extended period of time meaning years and years with the issue if it is intermittent.  A constant rate well into the 200s is a danger if left untreated for days but in a younger heart if any of it is intermittent the heart has plenty of time to recover.  Basically the doctor told me that we really don't technically need the atria.  I am sure that was just an exaggeration but in terms of our well being they pose little threat to us when things go wrong with them unless the ventricles are involved.  But even still a lot of things have to line up for any heart rhythm issue to cause sudden death.  It is a lot rarer than you are fearing. Honestly, the stress and anxiety will do you in sooner than any heart issue so it is important you work on that.

In any event, I understand about wanting to be informed but try to use the information to look at things objectively.  I know it can be hard when you have anxiety but just try to stop the fear thought train and take deep breaths and calm yourself.  This will get easier to do the more you do it.  Take care and put some extra focus on your child and less on your heart and see if that helps.  Hang in there.  It's going to be OK.

As I indicated above, I suspected this might have been the outcome. Michelle, I and mostly all successful "ablationees" had SVT that runs on and on.  Mine was self sustaining, and would never drop out on its own.  Consequently, it was easy to antagonize with merely a touch of the catheter.

So, where do you go from here?  My recommendation would be to wait for a while and monitor it.  Classic SVT will most likely become more frequent as you age.  Try some of the different meds available.  If one has little effect, try another.

....and remember that most physicians are quick to reach into your pocket to grab as much as they can.  Electrophysiology procedures are BIG BUCKS.  They get paid almost as much with a failed attempt as they do a successful one, so just be cautious.

Your groin will most likely be a fading soreness over the next couple of weeks.  When you take the bandage off today or perhaps tomorrow, you will be amazed to find just a red dot on either side.  Walking, especially if they didn't actually do any burning  is really the best medicine to get back to 100% quickly.

Sorry you had to wait so long.  There must have been an emergency that took presidency  Also sorry to hear they were unable to ablate.  Unfortunately that can happen.  I think you mentioned that your runs were not very long (16 beats was all they caught) and if they aren't that frequent that can happen.  I was very active by the time I went to get mine done having weekly episodes that would last hours at times so it only took one try for my EP to get mine going which is obviously key to getting it done.  I will say both my cardiologist and EP did not recommend meds because they said they really didn't stop it, only helped to slow it down when it did happen.  And anti arrhythmics are too dangerous for svt.  So just try and learn the tricks to get it to stop and as you get older if it gets more frequent you can try again.   But at least you know what to expect and will not need to be frightened.  You made it through and it wasn't nearly as scary as we imagine going in.   Rest up and try to remain positive.

Well i'm pretty bummed, went in at 8:30am and got prepared for the ablation, waited and waited until about 1:00pm, I almost left the hospital.

They tried and tried for a couple of hours and could not get the svt to start, I was awake the whole time.

Dr says I could go on meds and we will stay in touch, we will try again if it gets worse.

Glad I did it but also wish I didn't now because it sucked and my groin hurts..

According to your comment that it starts and stops in one beat I would say you did because the ablation is the best way to cure it for good.  You will otherwise always having it hanging over your head.  Stay strong.  The day will be over before you know it. Sending you well wishes.  Try to stay calm and centered.  It will be fine.

Did I make the right choice in doing this?

I'm kinda freaking out right now.....its almost time for my ablation.

I wish I could edit my post to add more, sorry for the second response.

My normal pulse is usually in the 50s so a bump to 170-180 is quite the difference for me atleast.

Most people that I talk with have a resting pulse in the 90s so when there SVT jumps into the 200s there is not much difference between me and the other guy except I have a lower pulse to start with in general.

Hopefully that makes sense.
