Figure 2 Top: Measurements of CSLA at end diastole and end systole during the same cardiac cycle are displayed. Electrocardiogram is shown at the bottom of the screen after the on-off signal. Bottom: Electrocardiogram and P1 (through the guiding catheter) with simultaneous P2 (obtained by the pressure wire) are displayed on the strip chart of the Electronics for medicine DR-12 system, after the on-off signal. CSLA = cross-sectional lumen area; ECG = electrocardiogram; P1 = aortic pressure; P2 = intracoronary pressure.
