waiting for cardiologist - NSVT

[lgrass94]

I'm awaiting another meet with my E.P to consider a 28 day holter in order to catch these strange skipped beats in having following SOME of my intense workouts. Very very rarely do they occur in my weight strength training but almost always with cardio routines. Maybe 2 or 3 times out of 10 I will not feel them. I am swaying towards NSVT or some other fibrillation process due to the sensation being a run of skipped beats for 5 maybe 6 seconds.

My question is - IF it is NSVT, can it decide to go on and off when it likes? So like people who do have it, do they have it all the time with exercise or w.e is the trigger, or just sometimes?

It comes into play for a reason like my E.P said to me for example, if you had a disease called ARVC then we would usually see a bigenimy or trigenemy pattern with a heart rate of 130 or above, meaning when it hits that 130 threshold then it pops up, there's no choice or hormone inputs to adjust it. Its just there!

Is this the same as NSVT?

It's somewhat discouraging to see that you don't follow any of the advice you get on this board. By all means, you can spend your time and money any way you want. But as your heart is healthy, you have done a lot of tests, I think that your problems should be managed by your GP and not an EP doctor.

I can try to give you an answer to your questions.

NSVT is a completely REGULAR rhythm (if you can feel the pulse waves at all during NSVT, some do and others don't). "Skipped beats" are not NSVT, even if they occur in what you call "runs" (which are not "runs" - they are ectopics in a pattern). NSVT (and SVT) is something similar to this:

X--X--X-xxxxxxxxxxxxxxxxx---X--X--X etc.

Atrial fibrillation is a completely irregular rhythm which usually sustains for more than 5-6 seconds. You don't have "skipped beats" during atrial fibrillation, the heart rhythm is just a mess with no baseline rhythm. Something like:

xx---x----xxx-x---xx--x-----xx-xxx----x

ARVC is not really a heart rhythm disorder, though it can cause ectopic beats and other arrhythmias. It's a structural heart disease, changes in the heart tissue. ARVC can't be diagnosed with a heart rhythm monitor! What you describe (bi/trigeminy always happening at heart rates >130 is how CPVT usually causes symptoms).

"runs" of skipped beats sounds just like PACs or PVCs. Which you already know you have.

If you are bothered by "skipped beats" when you have lots of adrenaline in your body, like after exercise, a beta blocker could help.

Its not that I don't believe or take comfort in what people are saying on here, its just that i feel this arrythmia to be more then just a Pac or pvc.

[lgrass94]

As you said about NSVT, any ecg would pick that up then. Given its a regular Irregular' rhythm? I'm sure my e.p said that I shouldn't worry about arvc as it tends to produce pvcs with a h.r around 130 upwards. So until I have seen the e.p again for this, can I ask, if you're correct and it turns out to be PACs or pvcs, why would they be so close together in the recovery phase of exertion? Surely its related to the heart muscle being compromised by the overload of exertion?

[is_something_wrong]

OK.

But why do you feel it is more than the PACs or PVCs you already know you have?

And why do you believe it's NSVT (if you do have regular runs of rapid heart rhythm) and not SVT, which it by 99,9% certainty would be?

[is_something_wrong]

PVCs (not PACs) which increase with increasing heart rate (for example, 1 out of 10 beats are PVCs at rate 130, 1 out of 5 at rate 150, 1 out of 3 (trigeminy) at rate 170 and 1 out of two (bigeminy) at rate 180) could, in some cases, indicate a heart under strain from some disease (CAD, myocarditis, ARVC, etc.)

The fact that you on occation do have some ectopics during cool-down is likely caused by the fact that plasma adrenaline has a half life of 2-3 minutes, but the heart rhythm slows because you are young and have a strong vagal nerve system which kicks in and slows the heart rate while your body is still full of adrenaline.

It's during exercise that your heart is working hard. Not during cool down.

in response to why do i feel its more them my usual pac/pvc, is specifically because they occur so closely together almost as one single 5/6 seconds of skipping as opposed to a strong sudden flutter when resting that i get. and the reason i believe it may be NSVT is due to it only solely occuring either during or in the recovery phase of exertion which is already a high heart rate.

i see your explanation on the plasma adrenaline side of it. why doesnt this happen every time then if its a release of too much of either one due to the exertion? surely this would happen every time, regardless of weather i am strength training or cardio training?

Andre, im just a guy, a normal young man who exercises alot, probably similar to yourself, and yes i am very anxious surrounding my heart i understand that. BUT my strong point is - why on earth would this only solely happen as a result of exertion, not when i have a panick attack, not when i am anxious and not when i am resting and have skipped beats?

do you see my point. its something in or shortly after i stop exercising that is threatening the rhythm as such into these runs of w.e they are

[lgrass94]

can i also ask you, lets say i take onboard that perhaps its a bout of PAC'S or some SVT arrythmia thats happening in the recovery process, is either of those anything that is treatable? and would they be dangerous?
