目的探讨实时三维超声心动图（RT-3DE）全容积成像及双平面法测量左心室容积的可行性和准确性。
Objective To evaluate the feasibility and accuracy of real-time three-dimensional echocardiography (RT-3DE) full volume and X-plane for quantifying the volume of left ventricular (LV) models.
BNP的释放与左心室容积扩张直接成比例。
The release of BNP is directly proportional to left ventricular pressure and volume expansion.
结果：福耳心痛散有明显增加正常家猫射血分数、每分心输量、左心室舒张末期容积的作用。
Results:FEXT powder has obvious effects to increase ejection fraction and heart output and the diastole late term volume of ventricular Sinister.
