DV多普勒血流波形心房收缩波形缺失提示心脏前负荷增加、右心功能不良。
The nearly absent atrial systole wave in DV Doppler flow imaging suggests presence of increased cardiac preload and right heart dysfunction.
结论两种药物联用降低心脏前负荷、后负荷,增加心脏每分输出量,改善心肺功能。
Conclusion Combination use of two drugs can decrease pre load and post load of heart, increase cardial minute ouput, improve the heart function.
结论血液透析有效降低心脏前负荷,增加心肌收缩力,改善心功能,同时也增加心脏后负荷。
Conclusion Hemodialysis treatment is effective in decreasing cardiac preload, increasing myocardial contractility and cardiac afterload, improving cardiac function.
小剂量时可扩张静脉,使静脉回流减少,左室舒末压下降,使心脏前负荷降低,降低心肌耗氧量。
If minor doses are used, they can expand veins, lessen the vein reflux, cut down diastolic pressure or left ventricular end and cut down the load of the heart, and reduce the oxygen consumption.
