I noticed that on some days, my palpitations are more frequent and more severe than others. On average, I get about 3-4 instances of palpitations per day. Mostly these feel like single premature beats, but sometimes they feel like a tickle or a flutter, possibly indicating couplets or NSVT. The most confusing thing is my symptoms during sexual/intimate activity. I am mostly able to have sex without palpitations, but sometimes I get horrid attacks during sex. It starts with single premature beats, and if I don't slow down, I go into bigeminy and suffer repeated NSVT episodes (usually 3 beat runs). For example, I experienced this around mid July this year. I was unable to have sex for about 3 weeks afterwards, as I would always get palpitations. Then it went away, and I was able to have sex just fine until late October, when it started happening again and lasted about a week. I'm back to normal again. Last night I had sex twice and attained a strong orgasm twice and I did not have any palps. Does the periodic nature of these attacks during sex indicate anything?
