人工心脏起搏器在我国已日趋普及。其治疗作用机制之一,是能提高心室频率,增加心输出量(CO)。现将完全性房室传导阻滞(CHB)右室起搏前、后的血液动力学对比研究结果简报如下: 实验研究健康成年杂种狗12条,雌雄不拘,体重7.5～18kg。3%异戊巴比妥钠(30mg/kg)静脉麻
Artificial pacemaker in our country has become increasingly popular. One of its mechanisms of action is to improve ventricular frequency and increase cardiac output (CO). Now complete atrioventricular block (CHB) right ventricular pacing before and after the results of the comparative study of hemodynamics are as follows: Experimental study of 12 healthy adult mongrel dogs, male and female, weighing 7.5 ~ 18kg. 3% sodium pentobarbital (30mg / kg) intravenous anesthesia
