Your heart has an internal pacemaker called the sinus node. It's a group of cells, located on top of your heart, that sends electrical signals into the heart and controls your heartbeat. Sometimes, ...

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 ...

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 ...

Please provide your email address to receive an email when new articles are posted on . Novel miniature pacemakers were safely implanted in neonates and infants requiring pacing. The pacemakers ...

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 ...

The human heart rate is under the influence of various hormonal and neural control mechanisms. Normally, conduction of an electrical impulse through the heart begins at the sinoatrial (SA) node and ...

Please provide your email address to receive an email when new articles are posted on . Wireless pacemakers may be a safe and effective short-term option for children requiring permanent pacing.

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 ...

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 ...

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 ...

Pacemaker implantation is a procedure that helps regulate irregular heart rhythms. The common conditions leading to the procedure in women differ from those in men. Following pacemaker implantation, ...
