A pacemaker is a small device that's placed (implanted) in the chest to help control the heartbeat. It's used to prevent the heart from beating too slowly. Implanting a pacemaker in the chest requires a surgical procedure. A pacemaker is also called a cardiac pacing device. See more A pacemaker is implanted to help control your heartbeat. Your doctor may recommend a temporary pacemaker when you have a slow heartbeat (bradycardia) after a heart attack, surgery or medication overdose but your … See more Complications related to pacemaker surgery or having a pacemaker are uncommon, but could include: 1. Infection near the site in the heart where the device is implanted 2. … See more Before your doctor decides if you need a pacemaker, you'll have several tests done to find the cause of your irregular heartbeat.

WebDec 1, 2024 · It is important to note that non-pacemaker action potentials can change into pacemaker cells under certain conditions. For example, if a cell becomes hypoxic, the membrane depolarizes, which closes fast Na + channels. At a membrane potential of about –50 mV, all the fast Na + channels are inactivated. When this occurs, action potentials …
