I'm a bit concerned. I've given up riding on the road for the time being (work and baby) so am entirely tubo based. I'm on a smart trainer with a heart rate meter for the first time and I'm noticing stupid high heart rates of ~220+bpm.
I'd figure equipment malfunction, but there are no irregularities, no spikes, gaps or jumping around, it's all totally fine and reasonable when I get on the bike and for all of my regular intervals and 'fun' sessions. The graphs tallies with RPE, climbs as you'd expect and recovers as you'd expect, just goes up too high.
Equipment calibration issues? Freakishly high, but natural heart rate? Some kind of irregular heart activity at extreme effort the meter can't track giving a high reading? Would my GP be interested in this?
