From the perfusion experiments with isolated rabbit heart and vessels were obtained the follow- ing results:(1)Potassium antimony tartrate produced depression of the isolated rabbit heart,and this depressant action became more marked when the pH of the solution was raised from the original value of 5.4 to that of 7.2;(2)At the same pH levels,the cardiac action of the potassium salt was slightly stronger than that of the corresponding sodium salt;(3)The slight vase-dilator effect of potass- ium anti...

从离体器官的灌注实验得到下列结果：(1)酒石酸锑钾对离体兎心有抑制作用，将其pH 从5.4调整到7.2时，作用亦随以增加。(2)在相同 pH 时，酒石酸锑钾的心臓抑制作用较酒石酸锑钠略强。(3)酒石酸锑钾对离体兎耳血管的轻微扩张作用，系由于该药溶液的微酸性反应，当将药液 pH 调整至7后即无作用。(4)对于离体兎肺血管则不问 pH 为4.8或7，均产生轻微的血管收缩作用。

Quantitation of the ventricular systolic and diastolic functions in the longitudinal axis is clinically relevant since the contraction of the ventricle in this direction is mainly due to subendocardial fibers.

心室长轴方向上的收缩和舒张由心内膜下心肌纤维的运动引起，可客观反映心脏整体舒张和收缩的程度。

Inhibition of 〓 exchange decreases the systolic and diastolic function of perfused hearts, whereas stimulating 〓 exchange improves the cardiac function, indicating that potentiating 〓 exchange may be a new pathway to improve the pump function of heart.

抑制〓交换可降低正常大鼠心脏的收缩和舒张功能，激动〓交换可增强正常大鼠心脏的收缩和舒张功能，提示增强〓交换可能是提高心泵功能的一个新途径。

And it still can increase coronary artery blood flow and reduce the oxygen consumption of cardiac muscle,thus making a cardiotonic effect and preventing Angina pectoris.

强心、降血脂、降血压：临床研究证实，山楂能显著降低血清胆固醇及甘油三脂，有效防止动脉硬化；山楂还能通过增强心肌收缩能力，增加心血输出量，扩张冠状动脉血管，增加冠脉血流量，降低心肌耗氧量等起到强心和预防心绞痛的作用。
