2% Burden? Let’s do the math.
So I just did my second 2-week ZIO patch monitor and for the second time, it shows a burden of about 2%. I thought this time had a decent amount of activity (definitely not my worst, but a good amount) but still just 2% burden. So, nice and low, no big deal, right? Well, I hate this % thing, because I am in frequent bigeminy and I feel it all, and it doesn’t feel like 2%. And though I’ve had this for over a year now, and am mostly used to it, it’s still SOOO disruptive.
But let’s ponder this… If the average person has a resting heartrate of about 60-80 beats per minute, then let’s just say you get 100 beats every 90 seconds (1.5 minutes). So 2% burden, I believe, translates to about 2 ectopic beats (or PVCs) in that 90 seconds. That translates to about 20 PVCs every 15 minutes, 80 PVCs every hour. That actually fits for me as I get about 4-8 strings of bigeminy an hour, and each run of bigeminy usually has about 15-25 PVCs. (Let’s call that an average as I get hours with lots more, and hours with none during a day.) So 2% seems reasonable. In numbers.
I know some of you out there have incredibly high burdens, and worrying about 2% may seem silly. But back to tolerable levels of burden… I just don’t see how someone living with 80 ectopic beats an hour, or 4, 5, or 6 runs of bigeminy an hour, is supposed to just ignore it. Even 1% means you’re feeling a PVC every minute and a half. 40 an hour. Am I doing the math wrong? How is that supposed to be normal living? Why is this considered "ignorable"?
Apologies. Feeling grumpy at the very symptomatic ZIO patch run that resulted in only 2%.
