Hello and Welcome,
Premature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a flip-flop or skipped beat in your chest. Premature ventricular contractions are very common — they occur in most people at some point.
Increased levels of adrenaline in the body, caused by caffeine, exercise or anxiety may bring on PVCs so cutting back on your caffeine is a good thing to try.
I would like to suggest you check into your stomach problems too with your PCP.
I am glad to hear you are enjoying the forum.
I look forward to getting to know you better.
