Pacemaker

medicine · heart · technology

Electrical lifesaver. A pacemaker is a small device that doctors place inside your chest, usually near your collarbone. It sends electrical signals to your heart muscle to make it beat at a steady, healthy pace.

Why hearts need them. Some people's hearts don't beat regularly on their own because of damaged electrical wiring inside. A pacemaker takes over that job, making sure blood gets pumped to the body the right way.

Battery powered. Pacemakers have tiny batteries inside that can last 5 to 15 years before needing replacement. Doctors can check how much battery power is left without any surgery.

Wireless updates. Modern pacemakers can send information wirelessly to your doctor's office so they can check if it's working properly without you coming in for a visit.

Millions depending on them. Over 3 million people worldwide have pacemakers helping them live longer, healthier lives with normal activity.
