1. Radiograph in the right anterior oblique projection showing catheters positioned for a standard diagnostic electrophysiology procedure. Three nonsteerable diagnostic catheters are introduced from the inferior vena cava into the right heart. Two 4-French catheters with four electrodes are positioned in the region of the right atrial appendage (RA) and right ventricular apex (RV apex). A 5-French catheter with six electrodes is positioned across the tricuspid annulus to obtain a His bundle recording (His). A nonsteerable 6-French catheter is introduced via the right internal jugular vein into the coronary sinus (CS) to obtain left atrial and ventricular recordings. Finally, a deflatable 7-French ablation catheter is positioned in the region of the low right atrium.
