  • Bisoprolol Beta Blocker & Bradycardia

    Hi everyone,

    Was diagnosed with HCM just a month ago, and a recent stress echo showed some obstruction to blood flow.

    My treatment has just begun -today I was just prescribed beta blockers (2.5 mg bisoprolol) to take once a day. I'm unsure if the cardiologists saw this or not, but my ECGs show that I have bradycardia as well. My 48 hour holter showed that my lowest heart rate (off beta blockers) was 44bpm (keep in mind that this was when I was deep asleep at 02:00). When I'm sitting doing office work, my heart rate stays in the low 50s (mid 50s the highest). Growing up (and up until my recent Dx) I've always been active: previous military involvement, sport fencing, soccer, hunting/fishing, rock climbing, scuba diving, hiking/camping, etc have been my life, but I'm not so sure how much this contributed to my slow heart rate. My parents also recently told me that when I was born, the doctors/nurses commented on my low heart rate was, but I don't think they even mentioned "bradycardia".

    My concern is the affect of beta blockers on top of my bradycardia condition. I'm looking forward to taking my beta blockers if it means that it takes away some chest pain, but I'm wondering how low this could make my heart rate.

    A couple weeks ago I was kept in hospital for 4 days, where they started me on beta blockers (25mg metoprolol) twice a day. I was only on them for two days; they stopped them because I had the stress echo the day after discharge. I felt ok with the 25mg; I didn't feel lightheaded all the time or had presyncope. The only time I experienced that was when I got out of the bed too fast to use the toilet, and this is something I've always felt at home (get up to grab something/answer the door, etc) before I even knew I had any of this.

    I am definitely going to mention this to my cardiologist, but I figured I'd put this out there to see if anyone with first hand experience has anything that they can contribute.

    Thanks for taking the time to read this and bearing with me.

    Cheers.

    "Normal" heart rate in textbooks is 60-100 beats per minute...... But what is normal for most is not necessarily normal for all.
    Athletes do tend to have a lower resting heart rate as their heart has become more efficient. Also people who meditate can have lower heart rates. Symptoms are probably more important than the actual number of beats per minute. If you are not getting enough oxygen to brain or muscles.... you feel faint or unable to do mild to mod exercise.....then there is a problem.
    The beta blockers will decrease heart rate..... I think a discussion with your cardiologist is the best way to go. If one class of drugs slows your heart rate too much, they may try another.
    I hope you make a point to go get evaluated at a HCM center of excellence. This gives you and your local cardiologist a lifetime resource of the most up to date testing, knowledge and treatment for HCM. There is a good guest blogger article on HCMbeat.com by Dr. steve Ommen from Mayo Clinic discussing the role of an HCM specialist working with local cardiologists.
    Best of Luck to you.

      Thanks for your quick reply.

      I agree that symptoms are more important than just numbers, and hearing this from someone else puts my mind more at ease. I don't feel faint and can do moderate exercise (just not for very long); never actually fainted in my life with the exception of this one time I was unexpectedly put in a sleeper hold in high school, but that's another story! I do get fatigue quite often but I was always told this was due to my hypothyroidism; maybe this new HCM diagnosis is the actual cause after all.

      I've heard of the HCM centres of excellence, but I believe these exist in the US. I live in Ontario, Canada, and am being taking care of by a cardiology team with cardiologists who specialize in various heart conditions including HCM. My first appointment with them is in late March.

      Thanks again for taking the time to reply.

      Cheers.

        I also have been an athlete for most of my life with a low resting heart rate. For me, I have a dual lead ICD which has the capability to pace my heart at 60 bpm in the event it gets too low from the beta blockers that I need to take for arrhythmia.

          Toronto General is supposed to have an excellent HCM Team.

            I'm on bisoprolol as well and other medications, my usual resting heart rate is 45-55 but sometimes it goes lower. I'm in Ontario too!
