The pacemaker is a tiny device weighing 25 to 35 grams, used for sending an electrical impulse to heart muscles to induce artificial heartbeat in patients whom the heart rate is very slow. The normal ...

SAN FRANCISCO, CA — Diagnostic MRI images to assess cardiac function, perfusion, and viability could be obtained in almost all patients with MR-conditional pacemakers in a prospective study [1]. The ...

Introduction: The cardiovascular system (CVS) is heavily influenced by the autonomic nervous system. Additionally, there is a functional alteration during the various stages of sleep. In nonrapid eye ...

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 ...

In the normal heart, the heart's lower chambers (ventricles) pump in sync with the heart's upper chambers (atria). When a person has heart failure, often the right and left ventricles do not pump ...

Generally, pacemakers improve quality of life for individuals who have a condition causing bradycardia, or a slowed heart rate. However, because there is an electrical device implanted near your heart ...

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 ...

Doctors use RF signals to adjust pacemakers so that instead of slicing a patient open, they can change the pacemakers parameters which in turn avoids unnecessary surgery. A study on security ...

M.B. Bose, a dental surgeon with an active practice, was suddenly getting breathless with little exertion like climbing a flight of stairs, and felt “extremely claustrophobic” even in a small crowd.

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 ...

A pacemaker can help your heart maintain a consistent rhythm. The procedure to insert a pacemaker typically involves a doctor making an incision in the skin that creates a “pocket” where the pacemaker ...
