我科自1989年以来,用硫酸镁治疗各种心律失常,有一定疗效。现将三例典型患者报道如下: 例1:男,53岁。因反复发作阵发性心动过速8年,多次在我科住院抢救,经介入性电生理检查证实为房室结双径,隐匿性预激综合症,左侧Kent氏束旁道,电刺激可诱发出房室折返型及房室结折返型心动过速及快速房颤,长期服用异搏停、胺碘酮、安搏律定等多种抗心律失常药,但快速心律失常仍经常发作。本次因快速房颤发作10~+小时入院。当时心率180~+次/分,血压测不到,立即静脉滴注10％G.S500ml+25％硫酸镁40ml,滴速30mg/分。1~+小时后心率开始减慢,2小时后心率减至90~+次/分,患者自我感觉良好,心悸、胸闷感消失,血压升至12/9kPa,6小时后转复为窦律。以后每日静滴硫酸镁6g,共10天,未再发生房颤或室上速。
Our department since 1989, with magnesium sulfate treatment of various arrhythmias, have a certain effect. Now three cases of typical patients are reported as follows: Example 1: Male, 53 years old. Due to recurrent paroxysmal tachycardia for 8 years, many times in our hospital for rescue, confirmed by interventional electrophysiological examination for atrioventricular node dual pathology, occult pre-excitation syndrome, left Kent bundle bypass, electricity Stimulation can induce atrioventricular reentrant type and atrioventricular nodal reentrant tachycardia and rapid atrial fibrillation, long-term use of verapamil, amiodarone, ambroxol and many other anti-arrhythmic drugs, but tachyarrhythmia is still often attack. The episode due to atrial fibrillation 10 ~ + hours admitted. At that time heart rate 180 ~ + times / min, blood pressure can not be measured, immediately intravenous infusion of 10% G.S500ml + 25% magnesium sulfate 40ml, drip rate 30mg / min. 1 ~ + hours after the heart rate began to slow down, 2 hours after the heart rate reduced to 90 ~ + times / min, patients feel good, palpitations, chest tightness disappeared, blood pressure rose to 12 / 9kPa, 6 hours after the turn into sinus rhythm. After a daily intravenous infusion of magnesium sulfate 6g, a total of 10 days, no further occurrence of atrial fibrillation or supraventricular tachycardia.
