Pacemakers can save lives. Many people have been given a new lease of life after their heart failures because of the ...

During an average lifetime, the heart beats more than 2 billion times. To you, it might just be a steady "lub-dub" that speeds up under pressure and slows as you drift to sleep. But behind that ...

Scientists just unveiled the world’s tiniest pacemaker. Smaller than a grain of rice and controlled by light shone through the skin, the pacemaker generates power and squeezes the heart’s muscles ...

Like a pacemaker, an implantable cardioverter defibrillator, or ICD, is a device placed under your skin. It also contains a computer that tracks your heart rate and rhythm.

Researchers at Northwestern University just found a way to make a temporary pacemaker that’s controlled by light—and it’s smaller than a grain of rice. A study on the new device, published ...

These short pulses—which penetrate through the patient’s skin, breastbone and muscles—control the pacing. Credit: John Rogers / Northwestern University “Our original pacemaker worked well.

When the wearable device detects an irregular heartbeat, it automatically shines a light pulse to activate the pacemaker. These short pulses— which penetrate through the patient’s skin, breastbone and ...

Tiny pacemaker is paired with a small, soft, flexible wearable patch that sits on the patient’ ... These short pulses— which penetrate through the patient’s skin, ...
