What you are having are premature ventricular contractions..It is not uncommon for younger people to also get PVCs..They can be caused by many variables,stress
, caffeine, smoking
, and some street drugs.. and sometimes if the heart is not getting enough oxygen
. And worst case CAD .I'm a 42 year old man. when i was in my early 20s I also would have episodes of PVCs. of coarse I ignored them. They would come and go for maybe 2 weeks at a time..when i was about 38 I started having them again, this time it was constantly all day!!! I work in an ECG lab and did 2 -24 Hr holters on myself finding I was have long episodes of bigeminy and trigeminy( that's when every other beat was a PVC(bigeminy) or every 3rd beat was a PVC(trigeminy) I was also having multiform ventricular couplets. the first 24 Hr test I DID, I THREW 18,000 in one day. I didn't feel bad from them, they just annoyed the hell out of me (not to mention they scared the hell out of me as well. I had a stress echo done and there was no blockage..cool..that ruled out CAD.So I stared taking a beta blocker
Toporol XL which in a matter of about 2 weeks they dissipated..I stopped the toporol about 6 months ago and still no PVCs...My Dr and I came to the conclusion that it was stress originated BUT MAKE SURE YOU GET SOME TESTES DONE TO MAKE SURE THEY ARE NOT CRITICAL..IN MOST CASES THEY ARE NOT CRITICAL ESPECIALLY IN YOUNG PEOPLE.
