Normal heart rate while sleep

Post by pivot » Wed Sep 06, 2006 9:47 am

Does anyone know what a normal heart rate during sleep should be. I have a pulse oximeter to wear tonight and I would like to know what a normal heart rate should be. Any info would be appreciated.
THANKS!!

Hi Pivot,

A normal heart rate is anywhere between 60bpm to 100bpm (beats per minute).

Hi Pivot,

The normal heart rate is normal anytime you are still breathing.

Mine usually runs around 51 to 58 with an occassional 48 sleeping according to my Nonin Palmsat 2500...

My pulse rate is always low during the day (around 70) but have been around for almost 51 years and several doctors said that was quite normal...

Good question heh??

So if?????

SO if my pulse usually runs 75-85 during the day, 65-75 would be OK for my pulse rate during sleep-WITHOUT CPAP, mind you. Just checking from my sleep study scoring.

I would think so even not being a doctor...

I know the Nonin Palmsat warning alarms go off below 50bpm so I just leave the alarms off...

The pulse oximeter was probably the best investment I have made to monitor the results of what the graphs in Encore Pro tell me...

Our President has a resting heart rate in the 50's and is praised by doctors for being physically fit.

With a resting heart rate between 51 and 58, I would guess you are in great shape and your blood pressure is normal.

Below 50 is called Bradycardia and above 110 is Tachycardia.

Bradycardia is common among untreated sleep apnea patients and can eventually lead to congestive heart failure.

Getting back to the correct resting heart rate. Normal for anytime is considered to be 60 to 100.

Well....

Resting during the day is in the 70's...

Not to bad a shape and good blood pressure...being treated for sleep apnea since January 2006...

Sometimes, even during the sleep study, it would dip to 48 or 49 however the normal average was around 62 sleeping with a peak around 85 or so...

So do I need to get excited about a couple of times dipping below 50 during my 8 hours sleeping? Using Lunesta but don't know if that has anything to do with a slower than normal rate....

The doctors didn't seem to worried about what they saw...

I too am interested in what is a normal night pattern.

When I started recording my SpO2 & h/b I was a bit concerned at the repeated bursts of h/b going up as high as 120 - this pattern of rapidly surging pulse rate is repeated throughout the night for me and seems consistent no matter what pressures or modes I set the xPAP to.

http://www.internetage.com/cpapdata/ (see the entries that include p/o data)

If we have anyone willing to venture an opinion on these patterns I am most interested. I really don't know if this is normal or not.

If I had to guess, I'd say these increases in your heart rate are occurring during REM dream cycles, and 120, is certainly not a rate to be alarmed about.

Is there a difference between bradycardia and having a slow heart rate? The reason I ask is that my sleep doctor reported I had bradycardia during my sleep test. I always wondered about that.

Anytime you have a heart rate below 50bpm you are experiencing bradycardia and it isnt good.

Amigo,

That sounds like a good explanation. It is difficult to know what to make of data like this if one doesn't have comparitive data. SWS also believed it to be arousals from REM sleep.

In most cases, the h/b starts to rise & immediately on this the SpO2 creeps up & both then settle back. The thing that sturck me was how quickly these bursts occur. I have only noticed a couple of instances of where SpO2 went down prior to the h/b going up. I also have been aware of some of these bursts occuring, seemingly 'out of the blue'.

Am certainly well aware of dreaming.

The other interesting aspect I have observed is how there seems to be a greater liklihood of 'pulse bursts' and declining SpO2 just before waking up.

Cheers

Yes, I see the same thing on my Nonin 2500 using ProFox oximetry software.

My mean pulse is 61 but for a brief second the chart shows 49 but only once or twice a night, and I also get the spikes along with oxy numbers rising proportionately.

I can make this happen by moving my finger and having it "lose" the pulse for a few seconds and this gets averaged out on the 2500 and I can make it show up on the graphs.

So yes, while I will agree below 50 probably isn't a good thing, going crazy over a couple of seconds because of finger movements etc is pointless.

I can export the data to a text file and looking at the data shows only for a 4 second period (which is what the 2500 does) none to twice a night as being 49.
