[Paroxysmal tachycardia with long QRS (left branch block type) in a female patient with accessory nodo-ventricular pathway. Role of the anomalous pathway in the electrogenesis of the arrhythmia].
The authors report a case of paroxysmal tachycardia with widened QRS (left bundle branch block morphology), where the electrophysiologic investigation shows an accessory nodo-ventricular pathway and suggests its involvement, as descendent (anterograde) pathway in a circular movement, the ascendant (retrograde) limb of which is the nodo-hisian pathway.
