Resting Heart Rate: 28 bpm?

I went for surgery once and my RHR was 32.

Much lower than that can risk fatal arrhythmia for some prone persons and was cited in a wave of early EPO deaths.

Have heard of RHRs as low as 20, so you may be fine. As always, this is a conversation best had with your doctor.

Letsrun,

I recently had a heart holter done for some precaution testing because of lightheadedness. I got my results back which informed me my RHR had dipped to 28 bpm at 6:50 A.M. I’m a collegiate runner and am an active person outside of running. Do any other runners have this low of a RHR? I’m considering getting another holter to try to get it to 26 for the world record. Guinness says it’s 27 bpm. Note, I had 2 cups of coffee the day I had the holter on.

It's individual. Coe had low 28's, whereas Webb had mid 20's. Jim Ryun never had lower than 55s, with most tests being in the low 60s (Daniel's).

There are slow 16 min 5k runner with resting RHR at 30 and then some 13 min 5k runners with same RHR.

What would be more relevant in terms of fitness is the recovery heart rate - El Guerrouj was known to be able to run a 800m rep in 2:00, and 1 min later he would be down to 65 bpm. A less fit runner might still be at 150 HR 1 min after a 2:15 800m rep at his 3-5k pace.

Also note, I’ve woken up many mornings and taken my heart rate as 12-13 beats for 30 second intervals. This was the first official documentation I had of an under 30 rhr. I’m 100% positive the lowest my heart has ever gone is around 25 bpm.

while you're at rest, the only thing really using oxygen is your brain, so your RHR is pretty much proportional to brain activity. If it's very low then your brain is probably pretty small and inactive.

Yes exactly, either the OP is full of BS or he's done one too many transfusions.

Its called bradycardia and you need to get it checked out ASAP.

Bet you are severely underweight as well. Bradycardia can result from self induced starvation state as the body tries to preserve the heart by slowing it down to dangerous levels.

Or it could be that it's because stroke volume is very high when lying down and resting?

There are people who wear lab coats and see people about heart issues all day. They’re called cardiologists. You should see one.

The little tremors continued rhythmically ; steady liquid drumbeats at precisely thirty-two to the minute. They did indeed shake the bed.

Or maybe not?

10-15 years ago when I was racing fit my resting HR was typically 28 and I would often see 26-27 when really relaxed. I was a decent but not great master at the time. I always “won” the LRC low resting HR threads. :-)

More than one doctor was concerned about it but the two cardiologists I saw over the years said it was ok based on my history and test results. In my less fit mid-50s it’s usually mid-30s to low 40s so it seems to be naturally quite low (still low enough to alarm new doctors) and the difference seems to have been the effect of training.

My suggestion would be to not worry so much if you know this to be normal for yourself, but to get it checked out to be sure, since it could either be normal or a sign of a more serious underlying condition.

You must have a very low RHR, maybe even while you[re typing as well.

Just checked. It's currently 54. I ran 2 hours ago and I've been snacking since then. It was 38-40 lying down yesterday.

There was a guy on my college team with RHR of 28 and he was fine.

OTOH a different man on the team (not quite as low a rate) was a national-level runner who got some standard cardiac testing done. A cardiologist saw the guy's EKG and said, "If this man walks up a flight of stairs, he'll die."

The runner won Boston a couple years later. Most cardiologists are not equipped (by training and experience) to make valid judgments about serious runners' cardiac health.

PS--My RHR was 37 a few years ago (age 60+) and that was definitely bradycardia. For a fair number of runners, by contrast, that would be absolutely normal.

I love these threads where people make up fake HR numbers to try and be impressive.

You're just exposing the fact that you're seeking attention or you can't count. Maybe both.

Just means you're in shape.

No they aren't making up numbers. Lots of runners have very low heart rates. You are just clueless

OP, whats your BMI (or just height and weight)? A super low HR in runners can be a sign of REDs.
