Echocardiography:Posterior left ventricular wall outer contour variation (w) in PI_w and PII_w (Fig. 3-9C), obtained by video and frozen image sector technique, and analysed under "video w" and "frozen image w".

Measurements in millimetres (negative numbers means a movement of the outer contour towards left ventricular cavity).
m = mean value, and I = 97,5 % confidence interval.
