The left ventricular (LV) posterior wall in @entity1 with @entity14087 or prior @entity583 ( @entity583 ) frequently demonstrates normal or supernormal motion to compensate for hypokinesis of the interventricular septum. This study evaluated the systolic motion velocity of the posterior wall in these conditions using a pulsed tissue Doppler imaging system. The study population consisted of 30 @entity1 with @entity1121 ( @entity1121 ) and @entity14087 , 25 with prior @entity583 and 30 normal controls. The systolic excursion of the posterior wall was obtained by M-mode echocardiography. The endocardial motion velocities of the posterior wall were obtained by pulsed tissue Doppler imaging. The systolic excursion of the posterior wall was significantly greater in the @entity583 and @entity1121 groups than in the control group, and was significantly greater in the @entity583 group than in the @entity1121 group. The peak systolic velocity of the posterior wall was significantly lower in the @entity1121 group than in the control and @entity583 groups, and the time from the electrocardiographic Q wave to the peak of the systolic wave of the posterior wall was significantly longer in the @entity1121 group than in the other groups. There were rough negative and positive correlations between the LV end-diastolic pressure and the peak systolic velocity and time from the Q wave to the peak of the systolic wave, respectively. In conclusion, LV myocardial contractility in @entity1121 @entity1 was impaired when compared to @entity583 @entity1 despite similar posterior wall motion on the M-mode echocardiogram. Pulsed tissue Doppler imaging method may provide new insights and allow further evaluation of @entity296 .
