Technically, bradycardia is an arrhythmia, but in its case it is just an abnormally slow heart rate. Also technically, any record showing BPM of < 60 is deemed to show bradycardia.

However, individuals have different factors going for them. Age, history of intense physical exercise, drug abuse, drug prescriptions, alcoholism/abuse, poor sleeping habits, poor nutrition (including bulimia and anorexia)...these are but some of what makes some of us have slow resting pulses while others might be in the 75-90 range and be perfectly healthy.

As a life-long athlete, my resting heart rate while watching TV 30 years ago was 38. A physician who took my pulse back then raised one eyebrow and asked me if I was a runner. Yup. That was all he needed to know. I'll bet my HR dropped into the 30-34 range while I was asleep.

I have seen where physicians feel the technical limit of 60 is too high. They felt that they wouldn't worry about bradycardia in all but a very few of their patients until it dropped below 50.

So, you have normal sinus rhythm (thumb up), but the attending physician feels you have a slow pulse. What was the number? What was your blood pressure at the time? If both were slow/low, you do have a pulse and pressure that is simply too low...........for you. There are medications, or there is the seemingly drastic step of a pacemaker. I urge you to read all you can. Pacemakers, like hearing aids, are a fact of life for literally hundreds of millions of people over the past 50 years. They get their hearing back, or much of it, or they find that they can bend over and garden again, go for hikes, ride a bike...and just not feel ill and worried. It will happen to you. And that's if you don't have an easily corrected lifestyle problem or something that medications can fix.

Good luck!
