LVEF was 51 % - 72 % the thickness of interventricular septum and posterior left ventricular wall was 8-12 mm and transvalvular mean pressure gradient was 8-26 mm Hg by cardiac ultrasonic examination by Doppler 's method .

随访心脏超声LVEF为51%～72%，室间隔及左 室后壁厚度8～12mm，人工瓣跨瓣压 差8～26mmHg。

It is concluded that after AMI left atrial compensatory systolic function was enhanced to keep constant atrial ventricular pressure gradient ( AVPG ) which is important to increase left ventricular filling . This compensation mechanism of left atrium corresponds to Frank - Starling 'S law .

结论：急性心肌梗塞后，左房代偿性收缩功能增强，维持一定的左房与左 室间的压 差（ AVPG），对增加左室充盈量起重要作用，符合Frank&starling定律。

The Clinical Research of Ventricular Gradient Variability in Diagnosis of Coronary Heart Disease

心室 复极 梯度变异性对冠心病诊断价值的临床研究

With the development of ECG detection technology some new detection means constantly used in clinical including ventricular gradient .

近年来，随着心电检测技术的不断发展，一些新的检验手段不断的应用于临床，其中之一就是 心室 复极 梯度。

Enrichment of cardiomyocytes from neonatal rat ventricular tissues by discontinuous percoll gradient centrifugation

采用Percoll非连续密度 梯度离心法纯化大鼠乳鼠 心室肌细胞

METHODS : 6 patients with OHCM who had underwent VDD pacemaker implantation were oberserved with the chang of left ventricular outflow track gradient and blood speed during follow up .

方法：对6例肥厚梗阻型心肌病患者植入VDD起搏器，并进行随访观察，观测其左 室流出道压 差及血流速度的 变化情况。

Other 28 patients underwent TASH successfully . Just after operations and 7 days left ventricular outflow tract pressure gradient decreased at no less than 50 % .

余28例均成功消融，术后即刻及术后7d，左 室流出道压力 阶 差下降≥50%。
