Pacemakers and implantable cardioverter defibrillators (ICDs) are small, battery-powered devices implanted under the skin to manage abnormal heart rhythms. Pacemakers deliver low-energy electrical ...

Methods: An MRI Device exam (GE 1.5T,WI) pioneered by cardiologists (>90% over 10 yrs; 100% over 21 years) was performed. A series of prospective questions using Boolean Logic Construct were answered ...

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 rhythm ...

Correspondence to Professor A John Camm, Cardiology, St George's University of London, London SW17 0RE, UK; jcamm{at}sgul.ac.uk The modern practice of cardiac rhythm management represents the constant ...

Estimates suggest that around three million Americans are living with cardiac pacemakers, according to the American Heart Association. Now, thanks to MountainStar Healthcare, a new kind of pacemaker – ...

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 last week ...

Engineers at Illinois' Northwestern University have developed the tiniest pacemaker you'll ever see. It's several times smaller than a regular pacemaker, and it's designed for patients several times ...

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 ...

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

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 ...
