Experimental cardiac tamponade was induced in anesthetized dogs by injection of isotonic solution of sodium chloride into the pericardium via a polyethylene catheter which was implanted before. Myocardial contractility was continuously recorded by using analog and digital computers. The pressure rise in the pericardium was accompanied by a significant growth of myocardial contractility indices. However, the increase in myocardial contractility under experimental cardiac tamponade did not make for complete compensation of cardiac pump function failure caused by restriction of the heart blood content on dilatation.
通过经先前植入的聚乙烯导管向心包内注射等渗氯化钠溶液,在麻醉犬身上诱发实验性心脏压塞。使用模拟计算机和数字计算机连续记录心肌收缩力。心包内压力升高伴随着心肌收缩力指标的显著增长。然而,实验性心脏压塞情况下心肌收缩力的增加并不能完全代偿因心脏扩张时血容量受限所致的心脏泵功能衰竭。
