Heart rate

I've recently become more aware of my heart rate since I got a fitness tracker.
It goes as low as 39 beats a minute. I have checked it manually and the tracker is accurate.
I don't have any symptoms, occasionally get a bit of dizziness when I am out running.
Not particularly athletic fit. I run about 2-3 times a week and have only started that since coronavirus started.

Should I be concerned and call my gp or just ignore it?
Over the last 24 hours it hasn't gone above 49.. unless I am doing something strenuous

Thank you

Hi, mine drops to 38 sometimes, I’m not aware it’s just going from my tracker but don’t know how correct they are.
I do always have low blood pressure though if that’s related.

My Samsung smart watch regularly shows my heart beat hovering around 100, even when I'm just watching TV. I just assumed it wasn't accurate.

That's a very low rate. My resting heart rate is around 55/56bpm. Average range is 60-100bpm i think

British Heart Foundation says:

Low heart rate (bradycardia)

A low heart rate is classified as a heart rate less than 60 bpm, instead of the usual 60-100 bpm. The medical term for a low heart rate is bradycardia.

For some young people and athletes, having bradycardia doesn’t pose a health risk. But if you have a low heart rate and are experiencing symptoms like fainting, fatigue and dizziness then you should make an appointment with your GP.

You can establish whether you have a low heart rate by checking your pulse.

A heart rate of 38-39 is well below the normal range, so I would recommend seeing a GP as bradycardia (slow heart rate) can be indicative of some fairly dangerous conditions (i.e: that certain vessels are slowly blocking up, that the heart itself is enlarged, which can be a problem in itself ...etc).

Better to go and get checked

We were told in training that anything lower than 50bpm in a patient who isn't a young athlete is worth investigating

I’d get it checked out. I had it after my last baby, they picked up on it with my postnatal checks and ended up having to stay in for a week and have every heart test going. Everything came back clear and I felt fine no dizziness or tiredness that wasn’t new bay related so I was allowed home but they where very concerned about it at the time as it’s unusual unless very fit.

I take a heart-selective beta blocker to slow my heart and prevent arrythmia and even that doesn't make my heart rate that low ( I didn't have a worryingly fast heart rate to begin with rhr was 70 now mid 50s).
If my hr dropped below 50 I know my dose would be cut and I'm asked to keep track.
I know we can't generalise as we are all different but I really think you should call your G.P.

Can I ask how old you are? The same happened to me except that I did have symptoms, feeling very lightheaded and fainted a couple of times.

My resting heart rate was around 48 going down to very low 40s at night. My GP referred me to a cardiologist and all tests were done, insuring wearing a heart rate monitor which did confirm the Fitbit ratings. 3verythibg came back normal.

His only concerns were the fainting episodes. He advised to cut down all caffeine, alcohol and to drink 3l a day of water. Medication is only given in extreme cases.

In the end, in my case it was all caused by the perimenopause. It's been better since fully in the menopause. Resting heart rate between 52 and 58, low to 45 at night. I still feel a bit dizzy and lightheaded at times but nothing like before.

Also what is your actual resting heart rate? Because the consultant did say that the occasional dip in 30s for just a few seconds at night is not that unusual. Your heart rate seems to only be so for a short time in your sleep.

Thank you everyone for your replies.
@dontdisturbmenow my resting heart rate is 42.
I'm 28 years old, no previous medical/heart problems.
I'll try cut down the caffeine and drink more water and see if it makes a difference

If you're a fit and healthy person, I personally wouldn't worry. Mine regularly goes into the high 30s and my average RHR is low 40s. I find it gets lower if I increase my running mileage and cut down on alcohol and caffeine.

Which tracker do you have and how long have you tracked it?
I've had a number of trackers (a cheap one, a huwaei one, and some other I can't remember) and only the Fitbit has really been reliable. The others were overall not far of when taking it at random times during the day, but off the scale at night , so that's one thing to consider.

Also it takes some weeks to get a clear picture of the the so if you've just started wearing one, it might take some a few weeks. My OH borrowed mine for a couple of weeks and it too came back very low the first week and then stabilised around 50. He is extremely fit.

If none of this apply, then yes, go to your GP. There is a heart condition (usually not dangerous but needs monitoring) that can show as a very low heart rate although the fact you have no real symptoms is reassuring.

dontdisturbmenow Fri 12-Jun-20 13:58:02

Also surprised it comes as 42 the when it averaged around 50 and it went under 40ish twice on the pic so again, that might not be correct.

@BMWL sorry not hijacking thread, just was curious about the same issues.
I have a Fitbit, worn continuously about 2.5 years

Yes low BP and low the are often related. My BP is very low too. It is also generic so not just fitness related.

My consultant said that if there are no heart defect and it's not causing issues, it is just a sign of a very healthy heart.
