Overview
Electrocardiogram
The EKG below is an interesting recording that shows a supraventricular tachycardia. The heart rate is around 185 bpm. It is somewhat unusual presentation for someone with angina. The arrhythmia terminated with adenosine which has a powerful cholinergic effect that blocks conduction through the AV node.

The EKG below is the recording of the patient who goes from sinus rhythm to a wide complex tachycardia at about 130/min. The wide QRS though disappears after nine complexes and is replaced by narrow complexes at a slightly slower rate. No p wave activity is seen. This is a supraventricular tachycardia with a form of abberancy. In this case we are probably seeing a rate dependent left bundle branch block or the effect of a left bundle branch block which persists for the nine complexes because of continued block in the left bundle from the depolarizations from the intact right bundle.
