Resting heart rate of 42-48bpm

Currently in A&E after being sent here by the out of hours. My heart rate is between 42 and 48bpm. I feel fine but didn’t first thing and it was about 35 and I felt faint. ECG normal, bloods so far normal, BP normal. Does anybody have a similar heart rate to reassure me that I’m not about to drop dead in my sleep? I’m waiting on one more blood test (trop T) and to see the doctor again but the first doctor wasn’t too concerned. I’m desperate to get home to my children. My 17 year old has put the 11 year old to bed and they are fine but I want to get back asap.

Normally pulse around 60-84 when it’s been taken.

I walk 50 odd miles a week on average but nothing else. I’m on medication for hypertension which is well controlled. The GP said that’s genetic and not a lifestyle thing. I generally eat healthily apart from every now and again.
Im worried that if it’s 42 now when I’m stressed sat on a very uncomfortable chair in A&E then what’s it going to be when I go to sleep. BP is currently about 125/74.

I am fit and well and not overweight or anything. I had a 24 hr tape before Christmas which showed it varies between 52 and 90. I’m on propranolol for palpitations and anxiety which will now need to be stopped. My heart rate used to go up to 126 at night with random anxiety thanks to general stress and menopause.

My resting heart rate is 37 and I'm healthy :)

I’m sorry you’re going through this, was it just feeling faint that made you go to A&E or were there other symptoms too?

Very very fit cyclists can have resting heart rates that low. These are people exercising all the time, you’d know if you were in that category. Do you do so much running and cycling that you ordinarily have a very low resting heart rate? What is it normally?
Did they check blood pressure as well?
Is yours normally on the low end?

I hope you get answers soon.

I think you’ll be okay. It is low but not really low. What is it normally? My resting heart rate is frequently below 60 and can fall to 48 overnight. I’m not overweight and eat reasonably well and exercise pretty regularly. Are you fit and well usually?

Mine rests under 50, always has. Otherwise I’m in good health
