Standard ADC components seldom provide enough flexibility to meet the conflicting needs of today’s medical designs. By Ian ...

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 ...

For the “QT interval”, which reflects the time for ventricular depolarization and repolarization, the team discovered 115 new genetic loci, and by combining all lead variants for this trait, they can ...

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 ...

The QT interval is the time from the beginning of the QRS complex (ventricular depolarization) to the end of the T wave (ventricular repolarization). The normal QT interval is controversial and ...

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 ...

Sinus tachycardia at 150 beats/min is present. The downsloping PR segment and upsloping ST segment make a smooth scooped-out curvature and are typical of Ta wave. Just as with the ventricular ...

A 62 year old male with a history of hypertension presents to his primary care physician for a routine check-up. His blood pressure is 220/110. He admits to not taking his blood pressure medications ...
