Termination of Supraventricular Tachycardia Complicating the Wolff-Parkinson-White Syndrome with External Countershock

Abstract
A case that demonstrates the feasibility of using external electric countershock for termination of paroxysmal supraventricular tachycardia complicating the Wolff-Parkin-son-White syndrome is presented. The occurrence of fusion complexes between impulses originating in the sinoatrial and atrioventricular nodes was observed.
