As the search for Savannah Guthrie's mother, Nancy, continues, a cardiologist explains how pacemakers work and if they can be ...

Sixty-seven years ago on Halloween, a rolling power outage wreaked havoc across the Twin Cities and at the University of Minnesota hospital, where cardiac patients were relying on electrical ...

Data from Nancy Guthrie's pacemaker has helped shed light on the events leading up to her kidnapping, but there are significant limits in how much data the devices can collect. Most importantly for ...

A new injectable, temporary pacemaker could help correct a heart arrhythmia in an emergency. This nanoparticle gel can regulate the heart’s electrical signals for up to five days before dissolving ...

A pacemaker, which unconfirmed media reports say Nancy Guthrie has, does not contain GPS and cannot be used to track a person's location. A pacemaker will continue to function even if it stops syncing ...

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 ...

Though a Northwestern-developed quarter-size dissolvable pacemaker worked well in pre-clinical animal studies, cardiac surgeons asked if it was possible to make the device smaller. To reduce the size ...

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 ...

A pacemaker can greatly improve daily life, and many people can return to normal life quickly. However, it is important to maintain the device and be aware of certain lifestyle changes. A pacemaker is ...

The tiny pacemaker sits next to a single grain of rice on a fingertip. The device is so small that it can be non-invasively injected into the body via a syringe. Northwestern University engineers have ...
