The sinoatrial (SA) node is the natural pacemaker of the heart. It generates electrical impulses that cause the heart’s chambers to contract, setting the heart rate. The SA node typically ...

Dr. Roach: My husband had a stress test done several years ago, and at the time, it was discovered that he had a bundle branch block in his heart. No Doctor suggests an ICM instead of a pacemaker ...

Because the sinus node keeps the heart beating normally, it is often referred to as a natural pacemaker. By helping your heart to beat, the conduction system also helps your heart send blood ...

An international team of researchers has revealed a game-changing, self-sustaining, and biodegradable pacemaker, the size of a grain of rice, that may transform post-surgical cardiac care ...

Nearly 14 million Americans live with arrhythmias. Learn to identify the warning signs of these common heart rhythm disorders and the breakthrough treatments offering 94% success rates.

“The electrodes of the pacemaker serve not only as the electrical interface to the heart, but they also establish — through the naturally occurring biofluids — a galvanic cell that acts as a ...

That’s a pacemaker – the world’s smallest in fact, which has just been revealed in a new study. Cardiac pacemakers are up there with some of the most impressive innovations in modern medicine.

A dissolvable pacemaker that’s smaller than a grain of rice and powered by light could become an invaluable tool for saving the lives of newborn infants., The device can be implanted ...

The heart has an electrical system, starting up in the right atrium with the natural pacemaker of the heart. Special conduction tissue leads to another structure — the atrioventricular node, which ...
