When I had my last pacemaker check the technician asked if my pulse was normal or irregular when I was in AF. When I said that it was irregular she raised her eyebrows but made no further comment. It is my understanding that a pacemaker does not cure AF but that it keeps the heart pumping blood steadily while the fibrillation is occurring in the atria. How does this affect the pulse rate? Does the pulse rate reflect the fibrillation or the blood pumping around the body?
