麻醉和手术的病人常发生心律失常,而目前常用麻醉药和操作引起的心律失常的发生率尚不十分清楚,因此麻醉中ECG监测是必不可少的,用Holter(连续)监测可发现60％以上的病人在麻醉手术时显示心律失常。围术期发生的心律失常多数并不严重,但当损害心肌功能,进一步影响心肌供氧平衡或转变为潜在威胁生命的室性心律失常则相当严重。检查和诊断导联选择麻醉时可选用标准双极导联、加压单极导联或单极胸前导联。现常用两个改进双极标准肢体导联来监测心律失常,即:(1)
Anesthesia and surgery often arrhythmia patients, and currently used anesthetics and the incidence of arrhythmia caused by the operation is not yet very clear, so anesthesia ECG monitoring is essential, with Holter (continuous) monitoring can be found in 60% The above patients showed arrhythmia during anesthesia. Perioperative arrhythmias are mostly not serious, but when the damage to myocardial function, and further affect the myocardial oxygen balance or potential life-threatening ventricular arrhythmias is quite serious. Check and Diagnostic Lead Selection A standard bipolar lead, pressured unipolar lead, or unipolar lead can be used for anesthesia. Two commonly used bipolar standard limb leads are often used to monitor arrhythmias: (1)
