1、立即停用洋地黄。 2、针对异位节律及心室率增快型心律失常的治疗: (1)钾盐 低血钾必须纠正,只要有心室易激性都应补钾。因为钾盐能使心肌的静息电位降低,舒张期除极速减慢,从而抑制异位节律点的自律性。可口服10％氯化钾10毫升,每日3—4次,必要时可静脉滴注,10％氯化钾10毫升溶于5％葡葡糖液250毫升内。同时应观察心电图,注意在心律失常纠正或出现高血钾心电图表现时立即停药。对高血钾,肾功衰及高度房室传阻滞者禁用
1, disable digitalis immediately. 2, for ectopic rhythm and ventricular rate of arrhythmia treatment: (1) potassium hypokalemia must be corrected, as long as the ventricular irritability should be potassium. Because potassium salt can reduce the resting potential of the myocardium, diastolic speed is slowed down, thereby inhibiting the autonomic rhythm of ectopic rhythm point. Oral 10% potassium chloride can be 10 ml, 3-4 times a day, if necessary, intravenous infusion, 10 ml of 10% potassium chloride dissolved in 5% glucose solution 250 ml. At the same time should observe the ECG, pay attention to the correction of arrhythmia or hyperkalemia electrocardiogram appears immediately stop the performance. Disable hyperkalemia, renal failure and atrioventricular block
