Solution
The correct option is A SA node
The most basic form of pacemakers monitor the heart's natural electrical rhythm. When the pacemaker does not detect a heartbeat within a normal beat-to-beat time period, it will stimulate the ventricle of the heart with a short low voltage pulse. This sensing and stimulating activity continues on a beat by beat basis. The primary purpose of a pacemaker is to maintain an adequate heart rate because the heart's natural pacemaker (SA Node) is not fast enough.
