I watched a video on YT that mentioned a drug study where a number of "apparently healthy" individuals were given a 24 hour Halter monitor exam. It found that about 30% had at least one PAC and about 40% had at lest one PVC. It also mentioned that less than 3% had couplets and less than 0.5% had NSVT. It got me wondering, if you were to monitor these people for 48 hours, 7 days, 30 days, and if it were possible, an entire year, 10 years, etc.. would there be any individuals that experienced NO ectopic beats whatsoever?
I assume this would be impossible in general, but what if you restricted your study to only people under 30 years old? Or people under 25 years old?
