Studies from our laboratory have demonstrated the presence of a vagally mediated reflex in acute cardiac tamponade. To determine the effect of thisreflex on cardiac performance, we continuously recorded hemodynamic parameters during induction of tamponade in 16 closed-chest mongrel dogs anesthetized with alpha chloralose. The studies were done 1 to 7 days following the insertion of a catheter in the pericardial sac. With increasing pericardial volume, there was a progressive deterioration of cardiac performance, the most marked changes occuring in the late phases of cardiac tamponade...
我们实验室的研究已经证明在急性心脏压塞中存在一种迷走神经介导的反射。为了确定这种反射对心脏功能的影响，我们在16只使用α-氯醛糖麻醉的开胸杂种犬心包压塞诱导过程中持续记录血流动力学参数。这些研究在将导管插入心包腔后的1至7天进行。随着心包容积的增加，心脏功能逐渐恶化，最显著的变化发生在心脏压塞的后期……
