TO THOSE with extensive electrocardiographic experience, especially if it includes a large proportion of young adults, the finding of the pattern of a short PR interval and a prolonged QRS complex ...

2. Short PR interval and delta waves consistent with Wolff-Parkinson-White (WPW) syndrome Explanation: Wolff-Parkinson-White syndrome occurs when a person is born with an "accessory pathway" that can ...

Purpose: Electrocardiogram (ECG) abnormalities are universal in infantile Pompe disease or glycogen storage disease type II, a fatal genetic muscle disorder caused by deficiency of acid α-glucosidase ...

This ECG shows every other beat having a short PR interval and a delta wave. This is called WPW-alternans. The accessory pathway that is exists is refractory on an alternating basis creating this ...

There is regular rhythm at a rate of 42 beats/min. The first five QRS complexes are wide (0.14 sec), and no P waves are seen before or after these QRS complexes; however there appears to be a P wave ...

The diagnosis is normal sinus rhythm, WPW pattern, PACs in bigeminal pattern, and pseudo inferior wall infarction. The rhythm is irregular and there is a pattern of group beating (ie, two QRS ...

A RECENT review of experience with the syndrome of short PR interval and abnormal ventricular complex occurring in otherwise healthy persons prone to paroxysmal tachycardia disclosed that a third of ...
