由于某些麻醉剂的药理性质,麻醉的操作以及手术时的刺激是引起麻醉下心律不齐的主要原因。尤其是胸腔内的手术心律不齐的发生远较其他手术为多。全身麻醉下有70—80％的病人都有轻重不同的心律的改变,但临床上用一般方法能查出的仅为6.5％。麻醉下心律不齐多为一过性的。持续的心律不齐,甚至影响血液动力改变的并不多见,除非有严重的心脏病或需行心脏大血管手术时,观察心电图才有必要。麻醉工作者应具辨 Due to the pharmacological nature of certain anesthetics, anesthesia and surgery are the main causes of arrhythmias under anesthesia. In particular, pleural arrhythmia occurred more frequently than other surgeries. 70-80% of patients under general anesthesia have different heart rate changes, but only 6.5% can be detected clinically by conventional methods. Under anesthesia arrhythmia mostly transient. Continuous arrhythmia, and even affect the hemodynamic changes are rare, unless there is a serious heart disease or need cardiac surgery, the observation of ECG is only necessary. Anesthetic workers should identify
