What is your resting heart rate.
Best measured in the morning after getting up when lying.

I know from top athletes that these have a deep heart rate (Lance Amstrong 32). So I am a little surprised at my deep heart rate. I'm not a top sportsman. I train about 6 hours a week. Therefore, I was interested in how the pulse of other amateur athletes is.

I do my best lying in the evening when I tell the g/f what I've been doing all day.

40-45 which results in problems if/when I have anaesthetic.

A low heart rate (<50 bpm) causes problems when donating blood.

Low resting hr also causes problems when you're in the hospital overnight and hooked up to a monitor. After being awoken for the 3rd time by an alarm, followed by a nurse arriving to check on me, I finally realized what was happening and asked them to set the alarm to something lower, like say, 40. Evidently there are limits to the night nurses' authority to make such changes. After much discussion they reluctantly lowered it to 50, which just meant it would continue waking me up every time I fell asleep. When I was younger, even 40 would have been a problem, as my resting hr back then was in the mid 30's.

Mine is 39.8. No wait, that's my age. RHR is just your age minus 220 isn't it?

Sitting at a desk, mine is 45. Maybe it's lower when I'm asleep but I can't really check it although I've also had problems setting off hospital alarms (the GP is always sending me to hospital because he thinks my HR is too low and wants to know why).

Last time I did a plasma donation my heart rate (in the arvo) was 52. It was pretty difficult to donate as the plasma/blood machine was constantly beeping at me for low blood flow.

Inconclusive.

Is that why his HR is so high?

@tinytoes:
What did you have for anesthesia problems. I had the problem that the anesthesia did not work well. They started the operation and I woke up. That could have been the case at the deep heart rate?
Feb 16, 2017 8:52 AM # 
JimBaker:
I've had the same problem of hospital heart rate alarms going off when HR would drop below fifty. I've also had the problem of waking up during surgery. I had never heard of them being related; interesting if that's the case.

JimBaker:
A CNN article on waking up during surgery hints that the anaesthesiologist may use heart rate to determine if you're conscious.

May I give a warning to those claiming low resting heart rates and thinking that is a sign of good cardio fitness.
Yes it usually is but remember that HR monitor is only giving you the average number of beats over a period. What if during that period the heart does not beat for a few seonds? That will lower the average, won't it? You think 'look at my low resting heart rate. I really must be fit!'
But there is a slight chance you could have condition called sick sinus rythmn where the heart will pause beating for several seconds and those pauses may get longer to the point where you pass out for lack of oxygen to the brain or to where your heart does not start again on its own.
So if your doctor ever says that she thinks it is time you have another ECG don't say 'nah, I have a low resting heart rate. I know I'm fit'. Take the test.
If you find yourself measuring the pulse in your wrist and notice that sometimes for a second or two or longer the pulse is not there then I would recommend you get to your doctor to get that checked out.

cmorse:
My weekly average usually runs 41 or 42. I wear a Garmin 235 which monitors HR from the wrist and often records a resting HR in the low 30s. I've often wondered if the low readings were anomalies, but whenever I manually check and compare, the garmin is spot on. My lowest readings often tend to come in mid-afternoon if I'm sitting quietly, or quite frequently a few hours after a workout, again if sitting quietly. My cardiologist has noted it's lower than most of his patients, but has not expressed concern.

I'm a low volume trainer, about 3-4 hours a week, this time of year it's only on weekends. But I don't have a sedentary occupation either...

I'd be lying if I told you I was asleep.
Feb 16, 2017 11:31 AM # 
jjcote:
But you're also on some kind of meds, right, Clint? Do they affect your resting rate, or just your max?
Feb 16, 2017 12:56 PM # 
andrewlee:
The lowest for me was 31 or 32, when I was about half my current age and very fit. Like cmorse, that was actually while sitting quietly during the day. In that instance, I was sitting in the back seat of a car, and I measured manually, counting for 60 seconds.

I was in the hospital overnight several years ago, and my heart rate was about 36-38 then, lying down awake. In recent years, I typically see 40-45 when going to bed, with it probably going lower when I'm asleep. My resting heartrate has always seemed lower when going to bed than in the morning.

cmorse:
Certain calcium channel blockers are known to lower both resting and max heart rates. But the one I am on reportedly has no effect on resting heart rates in most subjects.

But it also dilates blood vessels, so the heart doesn't work as hard, so it seems plausible that would also mean it needs to beat less frequently to get the job done, even at rest..

cmorse:
I do occasionally wear the garmin overnight, and note thay my lowest heart rates rarely occur while sleeping.

That's because you are dreaming about being in a parallel feature and get frustrated about it since you should have navigated better.

@ marten - always had good BP and mid 50s PR (age 25- 55). Returns to base rate really quickly after exertion (eg racing up Finish shute at end of Sprint event) Then started dropping but this coincided with doing consistent "long slow" jogging eg parkrun - 5km. New GP decided she might just check it out as consistently dropping 1-2 per year and this is often the case with aging people.
Specialist did Stress Test on treadmill, and decided I was fine as raised levels during stress and returned quickly.
GP agreed with me to review in 12 months. But about 7 months later had 1 episode of feeling queasy at top of very small hill during event and still have challenges going up hills (have done all my life) - just never seem to improve and run times not improving despite how much I do.
So back to specialist and I asked to do a stress test to "failure" not just to get 85% benchmark. Did Holter monitor 24 hour test and found pauses 24x but while sleeping and each lasting 1 sec. Lowest HR got to 38 about 4:30am. Specialist reviewed Holter and decided I was fine but referred me to another to do a Stress test to failure. Hooked up and monitored before, during and after. Both specialists agree I am fine and perhaps I need to change running patterns. One is an orienteer and he gave me his training suggestions.
Think I'll just have to realise I am exercising for health not to win races.
@gordhun - similar situation with tripping HR monitors during surgery but don't wake up or have problems - wow - wouldn't be liking that.

JimBaker:
Well, there I was thinking that my lowish resting heart rate was Training Effect and it may just be my Hypothyroidism.

Waking up during surgery was in fact far less stressful than running through greenbriar. After counting backwards as anaesthetic was administered until I lost the count, the next thing I recall was saying "ow" and reaching down to my lower right abdomen, where it felt like a greenbriar was cutting me from right to left. The surgical staff restrained me from touching the incision site, and told me to lie back down. (I could feel and hear but not see other than strong brightness). I groggily said something like "can I get some local anaesthetic for that". The surgeon (I think) said that they'd get me more general anaesthetic. I said that made more sense, and they laughed. Next thing I remember was waking up in post op, and then the surgeon and anaesthesiologist arrived and asked me to sign some waiver (and I had been feeling so good in the afterglow of the anesthesia). The difference with greenbriar is that it's rarely just one strand, and no one's there to give you anaesthetic, excluding some specialty events. Just another event with a few scratches and some recollections.

I once woke up during an Adam Sandler movie. I'm not sure how the pain would compare to your abdomen transplant but it was pretty awful nonetheless.
