Left ventricular lead localization. Biplane venograms (a; right anterior oblique 30°, b: left anterior oblique 30°) and lead localizing still frame (c; right anterior oblique 30°, left anterior oblique 30° not shown) to map left ventricular pacing lead locations (green ellipse on c) onto the modified American Heart Association model (d; green circle denotes lead location). Left anterior oblique images were used to determine the circumferential location while right anterior oblique images were used for longitudinal position
