A pacemaker is a small, battery-powered device that controls the heartbeat. Our heartbeats are controlled by a highly efficient, biological electrical system that ensures our heart steadily pumps ...

Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the tip of a syringe—and be noninvasively injected into the body. Although it can work with hearts of all ...

Heartbeats could one day help power something beyond hearts. A pacemaker is a device that helps regulate abnormal heart rates using electrical pulses. Leadless pacemakers, which are placed in the ...

An experimental leadless pacemaker is able to capture enough energy from the heart to partially power the device, according to results from a new proof-of-concept study. The prototype device harvested ...

Smaller than a grain of rice, new pacemaker is particularly suited to the small, fragile hearts of newborn babies with congenital heart defects. Tiny pacemaker is paired with a small, soft, flexible ...

Wireless or leadless pacemakers, commonly implanted in adults, may be a safe and effective short-term option for children with slow heartbeats, according to new research published today in Circulation ...
