A pacemaker is a small device that can send electrical signals to your heart. Here's who needs a pacemaker and how it works.

It is safe to have an MRI with a pacemaker, as newer models are MRI-conditional. But you'll still need to talk with your ...

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 ...

Tiny device can be inserted with a syringe, then dissolves after it's no longer needed. (Nanowerk News) Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the ...

The world’s tiniest pacemaker — smaller than a grain of rice — could help save babies born with heart defects, say scientists. The miniature device can be inserted with a syringe and dissolves after ...

Single-chamber ventricular leadless pacemakers do not support atrial pacing or consistent atrioventricular synchrony. A dual-chamber leadless pacemaker system consisting of two devices implanted ...

Background Cardiac surgery carries a heightened risk of bradyarrhythmias, but current permanent pacemaker (PPM) implantation ...

A new, tiny pacemaker — smaller than a grain of rice — developed at Northwestern University near Chicago could play a sizeable role in the future of medicine, according to the engineers who developed ...

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 ...

In a new frontier for deep brain stimulation, researchers used A.I. to develop individualized algorithms, which helped a skateboarder and other patients with Parkinson’s disease. By Pam Belluck ...

NEW YORK (AP) — Emily Hollenbeck lived with a deep, recurring depression she likened to a black hole, where gravity felt so strong and her limbs so heavy she could barely move. She knew the illness ...
