I do not know your age or condition and since your heart is different than mine and I am not a Cardiologist, I have no idea.

I'm 65 and mine is usually around 60 but can dip into the low 40's if I am overdoing it or lower with Covid. I use an AP that gives me a readiness score and suprisingly, it was flashing Red a day before Covid positive and despite feeling great and power great, it picked it up a day in advance. So, I use it.

HRV is a pretty big subject. Read Couzen's 5 posts on the topic and it might help.

I use the Garmin "stress" measure, which is a parameter derived from HR and HRV according to a super secret formula, and "Body Battery," which is cumulative measure of the "stress" parameter. If the high "stress" from a hard ride clears with a few hours of rest, say by dinner time, and my overnight numbers are good, I'm good to advance. If not, that's a sign I need to cut back for a day or two. If, after the acute stress wears off, I have an overshoot in the HRV and my RHR dips into the low 40s, that's another sign that I'm overcooked.

I also check a spot HRV each morning. The app I use also asks questions about subjective status, which is a good exercise. The resulting readiness measure generally tracks with the continuous measure and gives me a real HRV numbers which my level of Garmin watch doesn't do.

I also use how I'm actually feeling and performing as a reality check on all the gizmos and try to avoid the placebo/nocebo effects that come with them.

for those links. I'll be reading what's there once I've punched out for w/e ahead.

Thanks. So, these subjects were about 50 at the time of enrollment into the study. I have bradycardia and a HR < 100 bpm at 100 watts, but I'm way older than 50, normotensive, and no sign of AFib (yet).

are they concerned enough about the PVCs to put you on an antiarrhythmic or ablate them? individual PVCs don’t seem much of an indicator but for me any couplets or triplets are pretty strongly suggestive of VT risk. if i didn’t take flecainide, i’d have thousands of PVCs a day - pre ablation and pre meds it was in the 20k range iirc. 1/4 or 1/5 of all waking beats. a lot of docs like to say they’re harmless but others (and me lol!) are convinced they result in some kind of strain, to say nothing of poor perfusion?

although the SA node is in the RA, my understanding is that the signal conducts throughout multiple cardiac nodes, some of which are nerve bundles and some of which are muscle fiber. since athletes are remodeling the muscle of the heart, it doesn’t seem too surprising that the electrical system is potentially affected.

how much is too much is the trillion dollar question - and it probably varies per person based on difficult to predict factors. 😕

I've been taking a calcium channel blocker, verapamil, but it doesn't seem to do much. At rest, I only have a PVC about every 20", but going over 100 HR they start to come in bunches, sometimes combined with dropouts and I back it off. I think the next step is ablation. When I ride my rollers, besides my Garmin, I tape a phone to my aerobars and have Elite HRV up so I can watch what's happening. That's very helpful for not screwing up.

When I did a treadmill test, I had a period of Vtach afterward while I was still hooked up. That had them worried, though I didn't feel anything. But it was obvious that it would be dangerous for me to work hard on the bike outdoors.

ask them about other antiarrhythmics. VT when HR is decelerating seems to be a thing too, my worst episode pre-meds, ablation, and ICD was actually after a long run. makes me nervous when riding if there’s a sudden stop at a light.

Interesting thread this.

FWIW my max HR is 193 and my resting HR is around 60 when fresh, but creeps up to mid 60s with training fatigue. My HRV seems to vary from around 20 to low 40s when well rested.

So that puts my HRR at around 133. My VO2 max is estimated at around 50.

I think I have a high revving, low volume motor. No known heart conditions, but never seen a cardiologist.

Max HR is 165-167+/-m, resting (meaning while sitting/relaxing) is 50+/-.

VO2 max estimate is 48.

I have a low revving, high(er) volume motor.
