Heart Rate Monitor Inaccuracy
This is what was happening. I would bike on my trainer and at certain points my heart rate would drop, and I would be out of breath. I thought what was happening was my pacemaker was malfunctioning and that I was experiencing the same 2:1 AV block phenomenon that got me to get it in the first place.
So, this morning I spent about an hour on my bike at the hospital with my electrophysiologist, his nurse/tech, Matt from Medronic (my brand of PM) and a couple of other people. I biked at different levels of exertion. They stuck about 7 or 8 electrodes on me. I also was wearing my heartrate monitor (Polar H10).
Here’s what I learned. My HRM is a bullshit liar. I bike significantly harder than it indicates. At times it would show half or less than what was true. The takeaway is that I should pay attention to the Rate of Perceived Exertion not the readout from my HR monitor.
Anyway, that’s the story. My pacemaker and I are fine and longing for summer. Ride on!
