Description
Pacemaker comparison. At top are two of the earliest implantable pacemakers from the 1960s. At bottom are 21st Century pacemakers. Pacemakers are fitted in patients with a malfunctioning sinoatrial node, the part of the heart that initiates the heartbeat, or in patients with a heart block, which impairs the nerve impulses generated by the node. A pacemaker supplies electrical impulses along wires, to the heart to keep it beating regularly. The main body of the pacemaker is implanted in the chest just underneath the skin and the ends of the wires are implanted in the heart muscle.
