The echocardiographic findings in two patients with type A Wolff-Parkinson-White syndrome with pre-excitation localized at the anterior left ventricular wall are reported. The M-mode echocardiogram demonstrated premature anterior systolic motion of the postero-basal left ventricular endocardium that preceded the normal systolic contraction of the left ventricle. Despite the fact that the bundle of Kent reaches the epicardium of the left ventricular wall and that ventricular contraction probably begins at the subepicardial surface, the echocardiographic observations of the premature contractions were limited to the subendocardial layers.
报告了两例A型预激综合征患者的超声心动图检查结果，其预激位于左心室前壁。M型超声心动图显示，左心室后壁心内膜在左心室正常收缩之前出现过早的收缩期前运动。尽管肯特束到达左心室壁的心外膜，且心室收缩可能始于心外膜下表面，但对早搏的超声心动图观察仅限于心内膜下层。
