Ask the doctor. A year ago, my doctor recommended that I have a pacemaker because my pulse rate was too slow (38 on a monitor, 48 taken by hand). I did, and the rate of the pacemaker was set at 60. I am 90 years old, and my entire life my heart rate has been fortyish. Is my future affected by my pacemaker's timing?
