Short P-R Syndrome with Normal QRS and Paroxysmal Tachycardia

Syndrome de P -R court et QRS normal avec les crises de tachycardie Paroxystique ou le syndrome de (Lown-Ganong-Levine). Dans une enqete epidemiologique sur les ma­ladies cardiovasculaires chez deux populations rurales de Roudsar et Azarbaidjan oriental nous avons retrouve 6 cas de P -R court avec QRS normal. Dans cet article nous avons brievement passe en revue les vois de conduction auriculov...

The syndrome of short P-R interval, normal QRS complex and paroxysmal rapid heart action.

Syndrome of short P-R interval with abnormal QRS complexes and paroxysmal tachycardia (Wolff-Parkinson-White syndrome).

Short PR interval and narrow QRS complex associated with pheochromocytoma: electrophysiologic observations.

A patient with a short (0.10 second) PR interval, narrow QRS complex and palpitation is described. Electrophysiologic studies demonstrated the presence of accelerated atrioventricular (AV) nodal conduction. Subsequently, a pheochromocytoma was found. Surgical removal of the tumor resulted in normalization of the PR interval. These findings suggest that the short PR interval and the accelerated ...
