Mine too. I went through a bunch of cardiac testing, some invasive, when I had what appeared to be a run of ventricular tachycardia during a VO2max test in our lab back in 2013. I had developed a wicked addiction to energy drinks to get me through my doctoral program and wasn't able to quit. But all this testing got my attention and after being threatened with medications, I weaned off the energy drinks. I have less than 100mg of caffeine on normal days (2 diet colas). On ride days, I do ingest more caffeine and sometimes notice a lot of PVCs for about 12 hours after the ride has ended.
The only positive of all the testing is that my coronary arteries are squeaky clean! Considering I was morbidly obese for too many years of my life, I feel like I really dodged a bullet.
I'm probably more likely to take after my father who ended up getting a pacemaker at age 76 after a strenuous hike in the Grand Canyon. Electrical, not plumbing problems.
