Pulse in 30s? How low is too low?

38 replies

starsinthesky5 · 07/11/2025 00:53

Hey, bit of a strange one but I read online that slow pulse isn’t a problem as long as there’s no symptoms. Does anyone know how slow this applies to? Does there realistically become a point where too slow is bad even if asymptomatic?

only reason I ask is I’ve strangely had a really low heart rate today- I have a history of SVT (avnrt, atrial, junctional) as well as various intermittent blocks (2:1, wenckebach, Lbbb). Basically a walking talking ecg textbook at this point unfortunately.

i naturally have a low resting heart rate anyway (late 40s- low 60s) which I think is more due to how much intense exercise I do - I take medication (CCB) for my other arythmia but it doesn’t actually lower my heart rate, it just stops the problematic rhythm. My resting heart rate stays the same with/without the medication and I’ve not had any issues with the meds

today I felt a bit sick and tired and I checked my heart just out of interest and it was sitting about 31-39. I think the sickness was more just hunger tbh because I felt better after eating and I didnt have any other symptoms. The low pulse definitely wasnt to do with the medication because I hadn’t taken it today anyway.

im not sure why it was so low today but im assuming its from exercise

does anyone know, how low is too low? Or is it basically just the case if there’s no symptoms it’s always fine? I feel fine whereas when I previously had svt/blocks I felt unwell, but just wasn’t sure if I should be worried about this or not? I’ve attached my Apple Watch below- NOT so people can interpret it but just as proof of the low pulse

Yes but I had fallen asleep after posting last night and when I woke up it was ok today, I’m going to get an ecg done at a&e👍🏼

How are you now OP? I hope you have been seen now and there is a plan for you.

This is too low, and can absolutely cause you to feel sick and tired. You are severely bradycardic with symptoms and have a large history of arrythmia. Please call an ambulance and get checked over in hospital, you may need an IV infusion to keep your heart rate up.

I am a cardiology nurse, this pulse needs checking in hospital even without symptoms.

Just to update, it was ok this morning/afternoon but then seemed to suddenly drop again about 4oclock. I’m going to get an ecg done because it’s sitting between 31-37 at rest although I don’t have any symptoms so I think it probably is just from exercising

I actually fell asleep after messaging on here last night. I feel absolutely fine now but will definitely follow up with my cardiologist

It astounds me people will sit waiting for replies on Mumsnet rather than seeking actual medical advice.

It shouldn’t be too astounding that people would ask on a public forum if anyone has any knowledge or experience with things

of course I’m not relying on replies for exact medical advice, and of course in some situations it’s obvious someone needs medical attention, but in some situations it isn’t and there’s absolutely nothing wrong with asking if anyone else has experienced something

Hopefully no response as you're already in hospital, if not here's another voice to say this is a medical emergency, you need to be seen in A&E and NOT to drive yourself there.

A heart rate below 40 meets the criteria for absolute bradycardia. A medical emergency which requires urgent assessment.

SirCameronBridie · 07/11/2025 01:23

I don't think it's easy for any of us to help given you're on medication and have a history of heart issues. Most of the cases where a low RHR isn't a concern are "natural" situations with no other factors affecting the heart, and are not one-offs.

But to answer your question re. how low is too low, I think the lowest on record is 27, some athlete or other.

The women in my family have a RHR of approx. 39. We're all checked regularly because any new health professionals we see for any other reason usually panic when they take our pulse, and don't take our word for it that it's our norm.

I'll preface this by saying I'm no expert, but have had experience of cardiac issues (my own and husband).

Whilst you're fit and base pulse is low I suspect 30s is too low. My husband has an ICD (internal defibrillator) which doubles up as a pacemaker which steps in if he goes into the 40s.

I'd seek medical advice in your position. Better to be safe than sorry.

Do you have a cardiologist? I would call their after hours line just to make sure.
