When the heart malfunctions it sometimes needs a regulator. It’s called a “pacemaker,” a cardiac pacing device that keeps the rhythm of the heart steady and sure. For those who have heart failure or heartbeat issues, the pacemaker resynchronizes the heart and makes the heartbeat more efficiently.

The heart’s electrical system controls the heartbeat. But aging, muscle damage from a heart attack, or some kinds of genetic conditions can cause the heart to beat abnormally. It can get sludgy, therefore not pumping enough oxygen to the brain and other organs. If you heart is beating too slowly, the peacemaker sends an electrical signal to your heart in order to correct the beat.  Some pacemakers will even increase the heart rate during exercise as needed. Once implanted, the pacemaker makes sur…
