The diagnosis of many arrhythmias is difficult or impossible from the surface electrocardiogram. Often the use of special leads, including intra-esophageal recording, may contribute little additional information. The improved definition of atrial activity, conduction patterns, and timing of electrical activity made possible by recording from intracavitary sites is helpful in analyzing arrhythmias. Steinberg, Kroop, and Grishman (1) described the use of intracavitary leads in the diagnosis of several complex arrhythmias. Caceres, Calatayud, Nutter, and Kelser (2) (1962) employed this technique to study atrial fibrillation and commented on its potential diagnostic and therapeutic applications. However, the requirement of facilities and time
