Abstract
A patient undergoing double aortocoronary bypass grafting had Wolf-Parkinson-White syndrome without troublesome arrythmia preoperatively. Electrocardiographic, vectorcardiographic, and electrophysiological studies defined the functional properties of the anomalous bypass tract and suggested a posterior left ventricular insertion. Epicardial mapping identified early activation of the posterobasal portion of the left ventricle just to the left of the interventricular sulcus, beginning simultaneously with the onset of the delta wave.
