To the Editor: We read with interest the article titled “Cardiovascular Abnormalities in Late Onset Pompe Disease and ERT” by Forsha et al. 1. Ninety patients were randomized 2:1 to enzyme replacement ...

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 ...

The diagnosis is sinus tachycardia, short PR interval (enhanced AV conduction), and Duchenne muscular dystrophy. The rhythm is regular at a rate of 100 beats/min. A P wave occurs before each QRS ...

The correct diagnosis is sinus bradycardia and accelerated idioventricular rhythm (Figure 2). Figure 2. Courtesy of Philip J. Podrid, MD. The rhythm is slightly irregular at a rate of 50-54 beats/min.

What increases or decreases the intensity of the first heart sound? Four factors affect the intensity of the first heart sound. Since the M1 portion of S1 is much louder than T1, it is only important ...

American Heart Association researchers found heart rhythms in the first pig-to-human heart transplant changed from what is expected from a pig heart. The first pig-to-human heart transplant was ...

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 ...
