I too have these ectopic (or skipped or early) beats but this happens more when I am at rest. I notice that when I exercise, the beats seem to abate and I don't notice them. I've had them for about 2 weeks now and am still trying to find the source of these annoying beats (have ruled out alcohol and caffeine; unfortunately can't rule out stress due to anxiety because stress can't be measured
). I've read that in most cases, ectopic beats' origins can't be traced and only a small minority of people can positively assign reasons to why they have ectopic beats (usually alcohol or caffeine consumption).
Having said that, I've also read about people where they say that their ectopic beats are more pronounced during exercise, and they have learned to ignore it.
It would probably be best to have a complete round of tests done on you - ranging from ECG/EKG, echocardiogram and stress testing, the latter two if necessary. There are also other specialist tests that your cardiologist can adminster if he/she finds anything of concern in the ECG/EKG. In my case, my cardiologist said that there was no need for me to go for any tests other than the ECG/EKG which showed normal results, in the absence of any other symptoms and family history of heart disease. She just told me to keep my total cholestorol in check (this I blame on bad genes, high triglycerides in my body was inherited
) and keep on living a healthy lifestyle.
Bottom line is that once you're assured by a doctor/cardiologist you can trust that there is absolutely nothing wrong with you, stop worrying about it! These things can appear suddenly, and they *can* just disappear just as suddenly. The less you think of them, the better for your mental and physical health. I've been told that almost everyone has these ectopic beats; the difference are how many they feel in a day, and also whether they can feel these ectopic beats (most ectopic beats in otherwise normal healthy individuals can't be felt at all!). We just happen to fall into the "lucky" category of people where we can feel these ectopic beats (some like me, are also unlucky enough to be able to feel my heart beating whenever I lie down!)...
Take care, and get those tests done to put your mind at ease!
