DURING experimentally induced supraventricular tachycardia Moe and associates' observed in the dog heart aberrant conduction in one of the bundle branches, caused by retrograde invasion into that bundle branch, causing functional bundlebranch block. As far as we know no clinical record has been reported. Recently we saw a patient with supraventricular tachycardia and left aberrant conduction, p...

Symptomatic supraventricular tachycardia is a common indication for radiofrequency catheter ablation treatment. Often, supraventricular tachycardia is associated with sick sinus syndrome, which requires the implantation of a permanent pacemaker. Underlying structural heart diseases such as complex congenital anomalies or a history of prior cardiac surgery can hinder successful procedural treatm...

Electrophysiologic studies were performed on a 73-year-old man with swallowing-induced supraventricular tachycardia, in order to define the characteristics of this unique dysrhythmia in this patient. Swallowing reliably provoked an automatic atrial focus type of atrial tachycardia, which usually changed into an atrioventricular nodal reentrant tachycardia when a critical delay in atrioventricul...

Pacemakers were implanted in 10 of 14 patients with dizziness and syncopal episodes of long duration, due to sino-atrial block. Paroxysmal supraventricular tachycardia, notably atrial fibrillation, had occurred in 6 patients. Medical treatment was unsatisfactory in 3 of these and pacemaker therapy was given. This abolished both syncope and paroxysmal tachycardia. Sinoatrial block and supraventr...
