高血钾能引起室性自搏心律,多巴酚丁胺转复室性自搏心律国内尚未见报道,现报告一例如下。男患,63岁。因纳差、乏力半月于1990年3月7日入院。既往无心脏病史。入院时查体:T36℃,R21次/分,P82次/分,Bp16/10.7kPa,一般状况好,心肺(+),腹部饱满,肝肿大,下肢无浮肿。尿常规及肾功能正常,血清钾4.6mmol/L,肝功:TTT、TFT正常,ALT80 IU/L、AST70IU/L,表面抗原(+),凝血酶原时间17.9秒,凝血酶原活动度52.2%,ECG、超声心动图均正常,腹部B超、CT及选择性肝动脉造影检查证实肝癌诊断。入院经肝动脉栓塞治疗1月后,患者凝血机能明显下降,于4月26日晨突然出现腹痛、便血、血压下降至8.0/6.0kPa,心率由每分钟74次降至48次,反复出现阿斯综合征表现,急查血钾为7.4mmol/L,钠、氯、钙值正常,心电监测示室性自搏心律。给多巴胺以400微克/分浓度维持静点,仍为室性自搏心律,心室率48次/分,Bp9.33～10.7/5.33～6.67kPa,遂给多巴酚丁胺加入多巴胺液中以200 Hyperkalemia can cause ventricular stroke heartbeat, dobutamine recovery ventricular stroke heartbeat has not been reported in China, the report is as follows. Male suffering, 63 years old. Due to anorexia, fatigue half a month on March 7, 1990 admission. No previous history of heart disease. Admission examination: T36 ℃, R21 beats / min, P82 beats / min, Bp16 / 10.7kPa, the general condition is good, cardiopulmonary (+), full belly, hepatomegaly, lower extremity without edema. Urine routine and normal renal function, serum potassium 4.6mmol / L, liver function: TTT, normal TFT, ALT80 IU / L, AST70IU / L, surface antigen (+), prothrombin time 17.9 seconds, prothrombin activity 52.2 %, ECG, echocardiography were normal, abdominal B ultrasound, CT and selective hepatic artery angiography confirmed liver cancer diagnosis. After admission to the hospital for treatment of hepatic arterial embolism in 1 month, the coagulation function of the patient decreased significantly. On the morning of April 26, abrupt abdominal pain, blood in the stool and blood pressure dropped to 8.0 / 6.0kPa and the heart rate dropped from 74 to 48 times per minute. Syndrome syndrome, acute check potassium 7.4mmol / L, sodium, chloride, calcium value is normal, ECG monitoring showed ventricular stroke heart rate. To dopamine at a concentration of 400 micrograms / min to maintain the static point, still ventricular stroke is heart rate, ventricular rate 48 beats / min, Bp9.33 ~ 10.7 / 5.33 ~ 6.67kPa, was added dobutamine to dopamine solution 200
