作者等通过实验研究,观察酸碱紊乱对心肌起搏刺激阈值的影响,并探讨刺激时值能否作为酸硷紊乱时表示心肌应激性的标准。方法:20条杂种犬,用戊巴比妥钠(30毫克/公斤)麻醉,保持38℃恒温。以正压呼
Through experimental research, the authors observed the impact of acid-base disorders on myocardial pacing stimulus threshold, and to explore whether the value of stimulation can be used as a standard for myocardial stress when pH is disturbed. METHODS: Twenty canine dogs were anesthetized with sodium pentobarbital (30 mg / kg) and kept at a constant temperature of 38 ° C. To positive pressure call
