Fig. 1From: Global Bi-ventricular endocardial distribution of activation rate during long duration ventricular fibrillation in normal and heart failure caninesGlobal electrical mapping of the RV and LV endocardium. Panel I shows a fluoroscopic image of a posterior–anterior view of two basket catheters in the LV and RV and the RV defibrillation catheter. Panel II shows the basket orientation in the LV and RV. R, right free wall; A, anterior free wall; L, left free wall; P, posterior free wall; and S, septum. Apical electrodes are placed toward the center of the display, and basal electrodes are located near the peripheryBack to article page
