Left Ventricular Lead Localization. Biplane venograms (A, C) and lead localizing biplanes (B, D) were used to map LV pacing lead locations (black circle) onto the AHA 17-segment model (E). LAO images were used to determine the circumferential location while RAO images were used for longitudinal position. Mechanical delay times in a region surrounding the lead location (shaded region) can be determined directly from the 17-segment model (F).
