An electrocardiogram is a picture of the electrical conduction of the heart. By examining changes from normal on the ECG, clinicians can identify a multitude of cardiac disease processes.

Hypokalemia causes U waves in the ECG seen as a positive wave just after the T wave. Hyperkalemia causes peaked T waves initially, then an intraventricular conduction delay with a widened QRS ...

The resting electrocardiogram (ECG) furnishes essential information for the diagnosis, management, and prognostic evaluation of patients with congestive heart failure (CHF). Almost any ECG ...
