The three irregularly irregular rhythms are atrial fibrillation, atrial flutter with variable conduction and multifocal atrial tachycardia (similar to wandering atrial pacemaker). Atrioventricular (AV ...

An electrocardiogram (Fig. 1) of the Case Records of the Massachusetts General Hospital (in the September 18 issue) needs a few comments or corrections. First of all, the entire tracing in Figure 1 is ...

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. There are ...

An electrocardiogram, also called an ECG or EKG, is a simple and painless test that measures the electrical impulses of your heart to check for signs of heart disease. It's done through small ...
