What’s your lowest heart rate reading while sleeping?

[2doitnow]

I’ve been tracking my sleeping heart rate for months. Last night I got a reading of 30. Normally my low is 62. Anybody else experience this? Is it a glitch? I’m using the current generation 3 watch.

[doublepost=1551491967][/doublepost]YES according to the watch, my heart rate has gone under 40 all the way down to 35 total of 163 times in the past 3 months. My doctor said that unless I feel sick, tired, dizzy I should not worry about it. I exercise every day and i am very energetic...

Mine is usually around 43 when sleeping. When resting while awake usually upper 40s or low 50s. I usually can't use the ECG function because HR is under 50

 

[gymratjudy]

Lowest this year 38, normally in the low 40s while sleeping.

 

[CaptMarvel]

Age: 34
Highest HR: 210bpm
Lowest HR: 40bpm
Resting/Sleep: 52bpm

These are all according to the Health App. I’m almost certain the high and low are flukes.

Go see your doctor. Mine showed an at rest heartrate in the 30’s also... went to see my Cardiologist and left with a brand new pacemaker to go along with that shiny watch! This was 9 weeks ago. I’m only 33... not overweight at all. Seemingly healthy....until I wasn’t. Now my AW shows a nice resting rate of 60 BPM. 50’s while I’m asleep sometimes.

Best bet is to know for sure! That’s the best free advice I have!

That’s quite unusual for someone in their 30s to need a pacemaker. Asymptomatic bradycardia while sleeping does not meet any indication for a pacemaker and likely needs no treatment at all. Unless you guys are over 70, bradycardia is unlikely to be pathologic.

My average is 56 but I have dipped as low as 48 while sleeping.

I am 40, over weight and not in shape.

Everyone’s heart rate drops while sleeping due to increased vagal tone.
[doublepost=1551582763][/doublepost]From the British Heart Rhythm Society:

‘Benign’ Bradycardia during Sleep

Many studies have demonstrated a high prevalence of bradyarrhythmias during non-REM sleep in young, healthy individuals. In a cohort of 50 male medical students[2], a quarter had episodes of bradycardia (<40 bpm), while 68% had sinus pauses of >1.5s and a significant proportion had evidence of AV node conduction delay (see table). In asymptomatic individuals, these findings are of no prognostic significance and warrant no further investigation; the management consists largely of reassuring the patient (and referring physician).

Healthy individuals demonstrate an age-related increase in resting heart rate with relative loss of the normal respiratory sinus arrhythmia. In healthy individuals over the age of 60, sinus pauses and nocturnal Wenckebach are uncommon and should precipitate a thorough search for intrinsic conduction system disease. Current guidelines for pacemaker implantation should apply for advanced AV node disease (3rddegree, or infra-His type 2b) or symptomatic sinus node dysfunction. Correlation with symptoms can be particularly difficult with pauses during sleep; where there is a suspicion of syncopal episodes, empirical pacemaker implantation may be appropriate in the presence of prolonged sinus pauses (>6 seconds) even where correlation has not been demonstrated.

I was really concerned but found others with similar results. About three weeks ago I had a single reading of 31 at around 2am. Then the next day the same thing happened but had readings for about 10 minutes (5 readings total) between 31-34 then back up to 66. This is almost exactly half of my real pulse and didn't even realize this until days later when I looked. I read something about the frequency and sample rate causing 1/2 the pulse rate to be read. I've heard of it during exercise but maybe something with the way I was sleeping??

I've monitored for the past 19 days and never seen anything else happen again. I was in a hotel on an uncomfortable bed so unsure how I was actually sleeping.

Mine is usually between 42 and 45, the lowest i ever had was 39.

I’ve had a lot of low readings I just got down with a 14 day Holter monitor. Currently I have diagnosed symptomatic bradycardia, Bradyarrhythmia, LVH and syncope I’ve been hospitalized 4 times for passing out since dec 31. Friday I go to my cardiologist to see if I get a pacemaker they almost put one in me New Year’s Eve heart rate was in the low 40’s from 10 am dec 31 to Jan 2 at the hospital

Lowest asleep rating I’ve had was 30. I’ve benchmarked my watch heart monitor several times and find a 1 to 3 bpm margin of error. I’ll find out soon if I have a issue

My heart rate seems to be ~42 during the day at the moment. I've just started wearing my watch overnight & it's waking me up to warn me that my heart rate has dipped below 40 (goes down to 37). I'm 41, not overweight, not amazingly fit but I can do a 5k without breaking a sweat. I'm pondering going to see the Doctor as a precaution.

I get warnings from time to time during the day that it's been 38 for 10mins whilst I've been in a meeting etc. Same here though, I do 5ks 3 times a week and swim on other nights with the occasional 10 or 15k thrown in but not a marathon runner - I'm 51.

The Docs pretty much said that if I could sustain even a moderate level of cardio exercise that there was hardly any chance of anything being wrong. They did a 12 lead ECG and said it was very slow but very regular.

Hope your checkup looks OK too ^^

I wonder if wearing the watch while sleeping will affect the resting heart rate value. I just got the watch about 3 weeks ago, when the resting heart rate (RHR) showed usually at ~60bpm.
I recently have been working out a lot (actually the watch motivated me a lot), so according to the watch my RHR dropped to about 52bpm in those 3 weeks. Few days ago, I started tracking my sleep with sleep watch, and today my RHR stands at 48bpm. I feel this is pretty low, I almost never see such a low number in the heart rate charts during the day (even though when I really look through the data, I might find 1-2 points at this rate). However, when I go in the sleeping track chart, it does show lows of 45 in the middle of the night.

I was just wondering, does anyone feel the HRH gets off when wearing it at night, or does it seem like my numbers are off?

 

[TheSkywalker77]

I’m usually around 40-50. The lowest I’ve seen it was 39.

 

[Anonymous Freak]

Looks like 32 is my all-time low, but usual is 50-70.

 

[whsbuss]

Normal resting rate is 58-60 and sleeping goes to 49 at times, but mostly around 54 as I sleep

 

[iBreatheApple]

We are monitoring our vitals now more than ever. I am convinced (with no data to back it up) that we often have values well out of range for brief times during healthy sleeps cycles. Low oxygen, low heart rate, etc.

I'm high 80s and 90s while awake and when I sleep I dip into the 50s and 60s with some intermittent 40s. Everyone is different. New patters that are a change or concerning symptoms are obviously a different story.

Just found this thread. I have been a bit concerned by lower than normal resting heart rates, 50 to 55 bpm recorded on my Watch (originally an S5 but now a 7).

I have taken pulse measurements on my wrist (2 fingers) and they are consistently higher, usually about 60 bpm which is regarded as normal. I am beginning to think the Watch isn’t entirely accurate and would account for the differences.

I have done a lot of walking over the past few years and over the last year in particular, I’ve taken up running and my fitness has improved significantly. That would account for the relatively low rates.

Had anyone experienced differences in heart rates taken on Apple Watch and compared to measuring in another way, say by taking your pulse?

Your heart rate will dip while sleeping. That's normal. I was concerned and had mine (original SE) compared with a Holter heart monitor and it was in line. Mine will hit 38 bpm on occasions while sleeping.

 

[ahaslam]

My sleeping heart rate usually drops down between 50 and 60. I have seen it dip into the 40's, but I wonder if it's truly accurate.

 

[dstew201]

45-46


Here’s a shot while watching tv, years ago, when I did 3 mile runs 5 days a week

 

[Jackbequickly]

Is there not an alarm you can set for too low and too high of a heart rate? If so some should be hearing an alarm if you are in the 30’s.

 

[fdw777]

62 but I have a pacemaker that is set for 62 and seems to be doing it's job, during annual testing when the momentarily turn the pacemaker off my heartbeat is 35

My PM is set for a minmum 60. At night while sleeping I'm between 60-65. Last nights average was 63.

 

[G.McGilli]

I know this is an old, old thread that was dug up...

But - this is my biggest complaint about Apple Watch.

The lowest you can set for a HR Alert is 40bpm.

For those of us who are endurance athletes and therefore have Sinus Bradycardia - sleep in the 30's - it's just annoying to see everyday that you have 40 alerts because your HR was so low while sleeping.

Not sure why we can't have the option to elect 30 as the lowest.
