[The Lown-Ganong-Lewin syndrome--a rhythmologic unit?].
13 patients with the clinical diagnosis of a LGL-syndrome underwent a comprehensive analysis on account of therapeutically problematical tachycardias. In all cases the electrophysiological findings at most spoke for a partial av-node-shunt or for a small av-node, never for a complete bypass. The analysis of the tachycardia possible in 12 cases showed various mechanisms which by a stimulus circulating over a partial av-node-shunt could be explained in the sense of tachycardia only in 3 patients. It is concluded that different mechanisms underlie the clinically homogeneous picture of the LGL-syndrome concerning the development of a tachycardia.
