Resting HR on Bisoprolol

[LadyZ13]

Hi everyone,

I was put on 1.25 Bisoprolol in March when I had a heart attack and then told to take it twice a day in July when I went into Atrial Flutter after open heart surgery, meaning I'm now on 2.5mg.

My resting heart rate was mostly in the low 60s these last 6 months which I assumed was good. The doctors had said the Bisoprolol would slow my heart rate, giving it a bit of a rest for healing.

In the last couple of weeks, my Fitbit has been showing that my HR is around 80 when I go to bed and stays that way until about 4am when it drops. As a result, my resting HR has now climbed to 70. I know this is within normal range and not to worry (and I'm not paranoid... Much!) but it's a bit unusual for me. I'm back in normal sinus rhythm after a cardioversion.

What's everyone else's resting HR on Bisoprolol?

Hi LadyZ13, heart rate is very individual. My resting heart rate is 45-50s, was very fit pre Nstemi heart attack in July and I’m making huge progress in rehab. Completed phase 3 cardiac rehab which I found underwhelming and much to easy . I was in 3.75 bisoprolol when I left hospital but found it was spacing me out, got it changed to 1.25 but noticed my BP rising to high normal and asked to try 2.5mg which seems to suit me. My blood pressure is now normal - low normal ( 111/75 -107/75) .

Hi LadyZ13, as DWizza said, I am led to believe tha resting heart rate is quite individual. Mine is usually in the 60s. My advice would be to keep your cardiologist informed so they can ensure your treatmenr/medication is appropriate. Best wishes, Deano

Mine is around 50 on 1.25mg. We were told in our cardiac rehab not to go by the health watches as they are not that accurate.

I've seen that mentioned a few times but I've checked my Garmin a few times when having my HR checked at the hospital, both on the ward and at rehab, and found the watch reading the same as the hospital equipment.

Hi, as DWizza mentions HR varies greatly from individual to individual. My average resting HR is low 50s dropping into 40s overnight. After my NSTEMI I was put on 1.25mg of Bisoprolol and my HR dropped into low 40s and often into 30s and I was like a zombie with no energy. As a result the cardiologist agreed to stop it. I'd been in hospital a couple of times post HA and some nurses had commented/questioned giving me it with such a low HR. Been off it since April and HR back up to "normal". It can take a while to get meds balance right and it's worth talking with GP/Cardiologist if you have any concerns. I've got a telephone appt with my GP's clinician pharmacist tomorrow to discuss my statin, instigated by him as I've been having some issues. He's very good and it was him who sent me for blood tests which highlighted a VitD deficiency. He also switched me from lansaprazole to famotidine a few months back after issues with the lansaprazole.

All the best

Morning, that’s strange as Bisoprolol slows my heart rate so much that I had to self reduce it from 2.5mg to 1.25mg due to this and fatigue. This decision was later verified by my Cardiologist. It may be that you need a higher dose. Having said that 60-70bpm is an accepted normal range. Mine however is now in the 50’s but at least not in the 42-49 range like it was with 2.5mg. All the best, Andy

Hi on 10 mg my resting heart rate is 70 but my device is programmed to that. The other day I was in Afib and it was 75. I don’t know much about these things or even worry about them, because I have a pacemaker defibrillator fitted.

At age 71 I’m in the mid 50’s with an occasional blip into the 60’s, average over the last 4 weeks is 56 but single days have been as low as 43 in the past couple of months. 1.25mg dose here. Pre HA I was at 60 most of the time.

I use a Garmin, when talking to my GP at my last review I mentioned the dips in heart rate and he asked what monitor I was using. When I told him he accepted the readings without question and said they were accurate. He was quite happy also with my RHR levels.

My local cardiac rehab group use Polar monitors, I suspect that is a cost vs accuracy issue as the Garmin chest strap on its own is expensive let alone the watch!

Thanks so much everyone, your replies have helped. If my HR is still up when I see my consultant in a month's time, I'll mention it to her. Overnight it fell from 70 to 67 and seems to be back in the 60s when sitting down, whereas it was higher last week. Might have been a bit of stress or the after affect of Covid. Ideally I'd like to reduce, not increase the meds! I'm 39 so I guess you might expect a slightly higher resting heart rate on average than someone 20-30 years older? But all of your comments are helpful data points, thank you.

Mines normally around 50-55 I was very fit before anyway and it was only 60 normally depending on the weather it goes up and down slightly. I’ve had a few instances where it’s gone to around 90 and won’t come down after about a hour I get some chest pain take my GTN and within minutes it drops to normal, it’s very strange.

Sometimes I wonder if it’s my mind that’s pushing it up and holding it there with out me knowing?

I hope you get it sorted soon.

I’m on Bisoprolol and have been for a year now and my HR is usually between 58-65

[Sb1171]

3.75mg takes about 20 beats off my rate. Resting in low 50’s by day, dropping to mid 40’s at night. Seems to do the same at the other end of the scale - my max during intense exercise is now 160 compared to 180 without.

Hi LadyZ13,

I took bisoprolol 1.25 after episodes of AF. I already had a resting HR of between 50 and 60 but bisoprolol 1.25 dropped it into the low 40s and I could not tolerate it. I now manage with just Flecainide 50mg x 2ce a day and no bisoprolol . Best wishes to you

I'm on 1.25mg bisoprolol and my average heart rate when resting is usually in the mid 60s. Mid 40s when I'm sleeping

[LadyZ13 in reply to Deancooling]

Wow, that's lower than mine! I'm now more at 70-80 when sitting down and around 60-70 sleeping. I'll ask my consultant what she thinks about this when I see her in 2 weeks. Thanks for sharing.

My heart rate has dropped after Cardioversion and with continued use of Bisoprolol. It was in the region of 40bpm when the consultant withdrew the Bisoprolol immediately. After about four weeks now, I have risen to 71bpm with some spikes of 130bpm while I am asleep (if that doesn't wake me up).
