Ask the doctor: Would moving to a lower altitude help my heart rate?

Q. My doctor told me I have bradycardia. I live at an altitude of 5,765 feet — would moving to a lower altitude help my heart rate? Recent cardiac tests, including a nuclear stress test, were normal. My cardiologist said I did not need a pacemaker, and to keep on doing what I've been doing. I used to jog five miles a day and now, at age 85, walk three miles a day.

A. I wholeheartedly agree with your cardiologist that you should keep doing what you are doing. Walking is wonderful medicine.
