Schizophrenia was associated with cardiac electrical instability, suggesting arrhythmic vulnerability was an intrinsic disease feature.

Young, trained athletes may have abnormal 12-lead electrocardiograms (ECGs) without evidence of structural cardiac disease. Whether such ECG patterns represent the initial expression of underlying ...

Numerous factors can contribute to sudden cardiac death, from underlying disease after myocardial infarction to genetic variants that can claim young lives. In 'Bedside to Bench', Stanley Nattel ...

Early repolarization, which is characterized by an elevation of the QRS–ST junction (J point) in leads other than V 1 through V 3 on 12-lead electrocardiography, has been associated with vulnerability ...

Early repolarization is a common finding in young, healthy individuals. It appears as mild ST segment elevation that can be diffuse; however, it is more prominent in the precordial leads. The ST ...

Repolarization dispersion has been linked to echocardiographic measures of diastolic dysfunction in past research, and a recent study found it potentially indicative of pulmonary arterial hypertension ...
