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 ...

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 ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...

The heart may be small, but its rhythm powers life. When something throws that rhythm off—especially after surgery—it can become a race against time to restore balance. For decades, doctors have ...

Your heart’s job is to keep your pulse steady to pump blood throughout your body. Sometimes your heart rate is slower when you’re relaxing, and sometimes it’s faster when you’re exercising or stressed ...

Defibrillators and pacemakers help the heart maintain a regular rhythm. Defibrillators deliver a shock if the heart goes into arrhythmia. Pacemakers use electrical impulses to keep the heart from ...

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 ...
