If your heart beats too slowly or gets out of rhythm, a pacemaker can send an electrical pulse to that muscle and get it back on track. To do that, pacemakers need generators with batteries, and ...

Mechanical and electrical energy are linked and can be exchanged back and forth. Just like ultrasound converts electrical voltage into pressure or sound, we can engineer similar materials onto ...

"Mechanical and electrical energy are linked and can be exchanged back and forth," said lead study author Babak Nazer, M.D., an associate professor of medicine at the University of Washington in ...

Atrial fibrillation—a form of irregular heartbeat, or arrhythmia—leads to more than 454,000 hospitalizations and nearly 160,000 deaths in the United States each year. Globally, it is estimated that ...

Scientists have found a way to pick the best pacemaker for each patient, potentially making them last years longer. Researchers at the University of Leeds, Université Grenoble Alpes and University ...

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 ...
