In this “Heart to Heart” episode, Dr. Trey Baucum explains how the heart functions as an electrical organ and how pacemakers regulate its rhythm. Acting as a timer for tiny electrical impulses, a pacemaker keeps the heart beating in a steady healthy pattern. Dr. Baucum discusses different types of pacemakers, how advanced technology allows them to sense breathing rate and motion, and how they are highly programmable to fit each patient’s needs. He also covers what to expect during recovery and follow-up care. While the emotional adjustment period can be real, complications are rare. Most people return to their normal lives with improved heart function.
