A 67-year-old man with acute anterolateral myocardial infarction had recurrent ventricular fibrillation that required insertion of temporary pacemaker. When a permanent pacemaker was inserted stable ...

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 ...

When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...

Advances in knowledge of physiologic consequences of 3DAVB per se, and ventricular, as opposed to sequential AV pacemaking, with serial hemodynamic assessment and measurement of atrial natriuretic ...

PHILADELPHIA — Accelerometer-based atrial sensing with a novel, enhanced, automated algorithm in patients with atrioventricular block and a single-chamber leadless pacemaker in the right ventricle ...

At times it is difficult to distinguish atrial fibrillation from atrial flutter on the ECG. This example shows coarse "fibrillatory waves" in the setting of atrial fibrillation. This are of varying ...

THE question of how well the compensated human heart with a fixed rate in the physiologic range is capable of adapting to the demands for increased cardiac output has very practical implications for ...

This story is part of a series on the current progression in Regenerative Medicine. This piece discusses the regeneration of the cardiovascular system. In 1999, I defined regenerative medicine as the ...
