在低温麻醉下阻断循环进行心内手术,对心血管系统有重要影响,尤易发生心律不齐.低温麻醉时人类与动物的心电图改变已有报告.由于临床上成功地将低温麻醉及阻断循环用于心内直视手术,二者所致心电图改变近来国内亦有报告,但有关深低温麻醉阻断循环对心电图改变的报告不多,兹将本院深低温麻醉阻断循环实验的心电图改变初步总结如下. 材料及方法 In low-temperature anesthesia block the circulation of intracardiac surgery, the cardiovascular system has an important impact, especially prone to arrhythmia.Human and animal electrocardiogram changes have been reported at low temperature anesthesia.Because clinically successful low-temperature anesthesia and resistance Off-cycle for open heart surgery, ECG changes caused by both have also been reported in China, but the report on the ECG changes in the blockade of deep hypothermia anesthesia is not much, we will block the deep hypothermia anesthesia cycle experiments ECG changes are summarized as follows.
