To assess myocardial electric potentials late after coronary involvement secondary to Kawasaki disease (KD) we measured signal-averaged electrocardiography (SAECG) and QT dispersion parameters. Study ...

Membrane depolarization promotes extracellular signal-regulated kinase activation and cell proliferation via phosphatidylserine dynamics.

An arrhythmia (also termed cardiac dysrhythmia) is described as an irregular heartbeat caused by aberrant electrical activity in the heart. There are multiple categories of arrhythmia, each of which ...

A specialist tells how to interpret subtle changes on the ECG, including those caused by two life-threatening syndromes you might otherwise miss. Reading ECGs is like learning to appreciate art—it is ...

The rapid reduction in cell electropotentials induced by metabolic inhibitors is strong evidence for an electrogenic ion pump. According to Ohm's law, such a depolarization might be explained by a ...

PARIS — Use of periodic repolarization dynamics, a marker for repolarization instability associated with sympathetic activity, appeared to identify patients whose mortality risk would be reduced with ...

A patient in the hospital for metastatic Hodgkin lymphoma with significant abdominal distention displayed sudden onset of ST-segment elevations--often an indicator of a heart attack--however the heart ...
