Patient was educated on natural pacemaker of heart as follows:

1. Pacemaker is the site in the heart, which initiates the heartbeat.
2. A human heart has a natural pacemaker in the heart. This structure is called SA node or sinoatrial node. This site initiates heartbeat at a rate of 60 – 100 beats per minute.
3. Under normal circumstances, in a healthy heart with normally functioning SA node, the beats are evenly spaced out. This evenly spaced out pattern of heartbeats is called the normal heart rhythm or sinus rhythm.
4. Under certain diseased conditions of the heart or secondary to the use of certain drugs, the SA node may be damaged. Since the natural pacemaker is damaged, a second structure in the heart, AV node, will assume the job of initiating the beat. This structure is called the reserve pacemaker of the heart.
5. In patients, whose natural pacemaker is damaged or defective, an artificial pacemaker is implanted to replace the natural pacemaker, to initiate the regular heartbeat.
