In the treatment of atrioventricular block, dual-chamber cardiac pacing is thought to confer a clinical benefit as compared with single-chamber ventricular pacing, but the supporting evidence is ...

Cardiac implantable electronic devices (CIEDs) constitute a major breakthrough in the management of heart rhythm disorders. These devices largely include bradycardia pacemakers, biventricular ...

A joint task force from the American College of Cardiology and American Heart Association published a set of guidelines in 1998, [33] based on currently available data to establish a uniform set of ...

In the normal heart, the lower chambers (ventricles) pump at the same time and in sync with the heart's upper chambers (atria). Cardiac resynchronization therapy (CRT), also called biventricular ...

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 ...

A pacemaker is an electric medical device that’s generally about the size of a matchbox. A surgeon implants it under your skin to help manage irregular heartbeats called arrhythmias. Pacemakers can ...

Abstract A pacemaker is a device implanted into a patient’s chest; it sends small electrical signals via leads placed in the heart and is used to treat clinically significant bradyarrhythmias. This ...

A new study published in the Journal of Physiology on November 14, 2019, reports the development of a radically different type of cardiac pacemaker which could change the prognosis of patients with ...

Sinus node disease (SND), a common indication to implant a pacemaker, is associated with atrial tachyarrhythmias, specifically atrial fibrillation (AF), present either at implantation or detected ...
