A pacemaker is an electrically charged medical device. Your surgeon implants it under your skin to help manage irregular heartbeats called arrhythmias.
Modern pacemakers have two parts. One part, called the pulse generator, contains the battery and the electronics that control your heartbeat. The other part is one or more leads to send electrical signals to your heart. Leads are small wires that run from the pulse generator to your heart.
Pacemakers generally treat two types of arrhythmias:
✨tachycardia, a heartbeat that’s too fast
✨bradycardia, a heartbeat that’s too slow
