ventricular gradient

Objective To analyze the clinical value of peak myocardial velocity gradient ( MVG) as a noninvasive indicator of left ventricular ( LV) systolic or diastolic function.

目的探讨心肌速率阶差MVG评价左室舒缩功能的价值。

With color-coded M-mode TDI, the endocardial 、 epicardial velocities and the myocardial velocity gradient ( MVG) were calculated within posterior wall from left ventricular long-axis view.

a）组织多普勒检查：M型彩色多普勒测量左室长轴切面T波顶点时左室后壁（心内膜、心外膜）的心肌运动速度（Vendo、Vpi）、心肌运动速度跨壁梯度（MVGm）；

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%。

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。
