90 BPM at night?

[kyomagi]

Just quick question, im on verapamil 240mg every night for pvcs.  The last few nights iv been noticing that my HR is around 90 BPM when i am laying down!  My BP is normal and i usually have a full glass of water before bed.  I know its in the normal range, but should i be worried?  Im 27 Male, 225 pounds over weight but lowering it

Actually it can cause problems with arrhythmias. I lasted on it for a couple of weeks and had a problem with my SVT coming back after being without a SVT problem for months.

Sorry, in English it's sodium and not natrium ;)

No, nothing to worry about. I didn't know they used verapamil against PVCs, it's mostly used to control Afib.

Gredslori: I didn't think verapamil had a proarrhythmic effect. You can categorize antiarrhythmics in 4 categories:

I: Natrium blockers
II: Beta (cathecholamine) blockers
III: Potassium blockers
IIII: Calcium blockers.

Its group I and III that are known to cause arrhythmias (torsade de pointes). Verapamil is a class 4 antiarrhytmic drug and as far as I know, don't cause arrhythmias.

just taking your pulse can raise it to that level especially if you are worried about it and even if you are in bed. having said that, however, as with all antiarrhythmic drugs, verapamil can cause the same arrhythmias it is meant to get rid of. Talk to your doctor about this.

I wouldn't really worry about that. 90bpm is nothing to fear, quite normal actually. I was on Verapamil 240mg as well and for me it didn't really lower my heart rate that much.  The more you think about them the apparent and disruptive they seem to be. If you weren't calculating your pulse to see how fast it's going you wouldn't spend as much time worrying. Just knowing that anything below 100bpm is fine. Take it easy everyday and you'll eventually get it sorted out.
