Does a 200 heart rate when running merit concern?

To be clear, I wasn't wearing the HRM during the runs as the battery is dead right now. It was the treadmill that reported 200. I have no reason to question it as I've compared it to the HRM before and it was within 5bpm most of the time. But to say I'm not out of breath while running is a gross understatement. Today's run was extremely strenuous, I was close to collapsing by the end and my scalp was tingling.

At 30 years of age, your maximum heart rate should be in the range of 190. That's just a ballpark figure derived from the 220 minus age formula. Actual maximum heartrate can only be ascertained by testing....the maximum effort that cannot be exceeded.

At your max, you literallly cannot work any harder, and you can only sustain the maximum for a very short time. It's an all-out effort.

I always question the HRM devices they put on treadmills and other equipment.... I'd first check it against a better machine of known accuracy.

For exercise purposes, you should only be working in your "aerobic training" range.....65-75% of max.

You're either running way too hard, or you have a defective heart rate monitor.

Your deep sleep sounds in the normal range, but on the high side. Your waking level being around 100 is probably okay, especially if moving around. But 200ish is a lot more than it should be. And that's likely a defective monitor if you're not even getting out of breath during your runs.

I'd find another monitor to test yourself with. Strongly consider checking in with your doctor. And if you're getting out of breath during your exercise, slow your pace way down.

that is a little fast, but if you feel fine then I would not worry about it, those charts are not accurate for all.
