What level of slow heart rate (bradycardia) is considered dangerous?

I am taking Metoprolol Succer. 25 mg for B/P and heart rate twice a day, along with Amlodipine 5 mg. I also take clonazepam 1 mg at night it helps me to sleep along with a .05 if I get sudden blind side panic attacks, anxiety. I did notice in time my heart rate dip to 38 bpm at night and during the day when I was in rest mode. Yes! definitely get a second opinion. Klonopin does lower heart rate and in some cases, Zoloft has the same effect. I started having PVCs at the age of 42 yrs. and Metoprolol came into the picture along with the severe panic disorder. this past April is been 2 yrs. that I had a Pace Maker doing fine at 74 years, just finish cutting the lawn.

I was told anything below 50 is not acceptable, unless you are resting and are a world class athlete.

But I'd check in with a different cardiologist. You may need to change your med.
