Mechanical and electrical energy are linked and can be exchanged back and forth. Just like ultrasound converts electrical voltage into pressure or sound, we can engineer similar materials onto ...

Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the tip of a syringe—and be noninvasively injected into the body. Although it can work with hearts of all ...

A pacemaker is a small electronic device that helps keep the heart beating regularly. It can represent a life-changing treatment for heart conditions such as arrhythmias. It is generally not too ...

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 ...

Last week, Abbott began the commercial launch of its new leadless pacemaker, which it believes is a historic development in the world of cardiac rhythm devices. Aveir DR is a better option than ...

A pacemaker may be useful for atrial fibrillation (AFib) involving a slow heart rate or other heart conduction disorders. However, doctors may recommend lifestyle changes to manage AFib before a ...

CRT is a surgical procedure in which doctors implant a pacemaker in both the right and left sides of the heart to help your heart’s chambers beat together. The goal is to improve heart pumping ...

Normal cardiac function depends on the adequate timing of excitation and contraction in the various regions of the heart and on an appropriate pacemaker rate. This complex task is implemented by the ...
