3. Figure 2
Electrophysiologic study in the second patient. Surface leads 1, 2, and V1 are recorded simultaneously with intracardiac leads in the right atrium (RA) and right ventricle (RV). During ventricular drive (S1), premature stimuli (S2, S3) are introduced which initiate a ventricular tachycardia of variable morphology.
