I just wanted to see if anyone had anything similar. For quite some time now, maybe once a month, I've been having short episodes (5 second or less) where I feel like my heart is out of whack. It occurs when I'm resting. I've never felt any problems while exercising. I'm a 21 year old guy, 6'3", 230lbs, and in pretty good shape. I typically exercise frequently. When it happens, it feels almost like my heart skipped a beat or two, and I get the urge to cough. Almost always, as soon as I cough, everything seems to go back to normal. The episodes are so short that I don't really have time to take notice of everything that goes on. I do, however, recall one instance where I stood up quickly, felt dizzy, and had this sensation. It's possible that I've felt momentary dizziness before with this condition, but it's hard to remember. The reason I bring that up is because I've read that dizziness with this problem is a sign of a more serious problem. Admittedly, I am a bit of a hypochondriac at times, and I'm also an anxiety sufferer, so I'm hoping this is yet another physical manifestation of stress, although I'm hoping you guys have some insight. Thanks!
For the posterity of anyone who reads this with the same issue, I figured I would update this post. I went to the doctor, and to be safe, you should probably do the same. The doctor ran an EKG, checked my blood pressure, and listened carefully to my heart. In my case, the tests came out totally normal, and he said an occasional skipped beat (up to 10 times per minute, believe it or not) is normal and acceptable. He suspected I have a condition called PVC, or Premature Ventricular Contractions, which isn't too much of a problem. I've been advised to avoid caffeine and decongestants, because they make these sensations more frequent. Again though, when in question, please see a doctor. I was amazed - they performed an EKG right in my general practitioner's office. I was under the impression I'd have to see a specialist for that.
