SUMMARYEchocardiographic waves from the posterior left ventricular endocardium were recorded in 30 normal subjects and in nine patients during 13 anginal episodes. At rest the normal maximal systolic endocardial velocity (SEVM) was 6.2 + 1.4 cm/sec, the mean systolic endocardial velocity (SEV) was 4.1 + 0.7 cm/sec, and the systolic endocardial excursion (SEE) There have been recent reports of abnormalities in LV compliance in patients with coronary artery disease4' 5 suggesting that diastolic changes can also occur with ischemia. Since reflected ultrasound is suited to studying both systolic and diastolic events, we applied these technics to study the motion of the posterior LV wall during induced angina pectoris.

Posterior wall velocities have been advanced as a useful technic for the assessment of left ventricular function. To evaluate the echocardiographic effects of regional myocardial infarction on posterior wall motion (PWM), measurements were obtained in 22 open-chest dogs. Coronary artery ligation produced infarction of the apex in 11 dogs (group I) and the posterior wall in 11 dogs (group II). Echoes were thus received from noninfarcted myocardium in group I and from infarcted myocardium in group II. Postinfarct recordings in group I showed no significant changes in posterior wall velocities or excursion. In contrast, group II showed striking changes in the contour of PWM with a large initial posterior displacement (aneurysmal bulging) during isometric contraction, followed by a slow anterior movement during ventricular ejection and then a rapid anterior recoil motion during isometric relaxation. Mean posterior wall velocity fell from 31 + SE 3 mm/sec preinfarct to 13 + 4 postinfarct (P <0.01); from 33 + 4 to 21 + 5 mm/sec during atrial pacing pre-and postinfarction (P < 0.05); from 30 + 3 to 18 3 mm/ sec during volume loading with dextran 20 ml/kg (P < 0.01); and from 32 4 to 5 ±2 mm/ sec during aortic constriction (P < 0.01). Corresponding reductions in posterior wall systolic excursion were observed.Simultaneous hemodynamic measurements revealed moderate depression of ventricular performance in group II, but there was no significant correlation between the changes in hemodynamic parameters and echocardiographic velocities following infarction.We conclude that the marked changes in PWM following posterior infarction were due to echocardiographic detection of dyskinesis in the infarcted area rather than to generalized changes in ventricular function. Posterior wall velocities are not a reliable index of left ventricular performance when localized dyskinesis, as indicated by abnormal PWM, is present. Additional Indexing Words: Ultrasound Dyskinesis Ventricular aneury< D IAGNOSTIC ultrasound has been utilized in the measurement of ventricular volumes and wall thickness." 2 More recently, attention has been directed specifically toward the left ventricular posterior wall echo. The velocity of anterior displacement of this echo during systole has been related to the rate of decrease in ventricular sm Asynergy Posterior wall velocity the left ventricle produces a "cloud" of bubbles (arrow), otutlininig the borders of the ventricular cavity.

The ultrasound reflection technique was introduced into cardiology in 1953, and in 1955, the ultrasonic Doppler technique was introduced. The dawning stage of ultrasound diagnostics of the heart was the ten year period prior to 1965.During this stage, besides the afore mentioned techniques, there were only a few attempts to use ultrasound for heart diagnostics.In the next age, from about 1965 to 1975, the leading type of the cardiac ultrasound was M-mode echocardiography.M-mode echocardiography was the first generation of ultrasound diagnostics of the heart used in routine practice. This period may be called the age of M-mode echocardiography. During 1975 to 1985, the leading technique was real-time two-dimensional echocardiography, with and without the Doppler mechanism, which was the second generation in routine. This period can be called the age of the two-dimensional echocardiography. The period from 1985 to the present time may be called the age of the color Doppler, which has been the third generation of the cardiac ultrasound.However, since the middle of this last age the cardiac ultrasound has been showing the most diversification of techniques and usages. Therefore, it is uncertain whether the age division as mentioned above can be continued. The period extending over the last age and present time may be the second dawn of the cardiac ultrasound.
