New onset pvc's maybe due to increased ritalin use (but never had these before despite being on it for many years)? Assoc. chest pain and possible displaced apex beat, do i need to be worried about HOCM or dialated cardiomyopathy? No SOB but heart feels like it flipflops or like about to explode (maybe wrong word choice but only description i can think of). I heavily and regularly exercise as muay thai/mma fighter/trainer and no problems in gym. Problems(pvc's and chest pains) feel most numerous when I have time away from the gym like 2 weeks off or so. Smoking aslo seems to aggravate the pvc's and chest pain. I would say i have several thousand pvc's a day and know thats either associated with or a progression to dialated cardiomyopathy.

Summarized question: Are PVCs associated with or progress to dilated cardiomyopathy?
