心脏性猝死中,75%～85%为室性心动过速及心室颤动所致。扭转型室速是介于室速及室颤之间的过渡型心律失常,在心脏性猝死中,扭转室速的发生率高达32%。本文报道1例应用苯妥英钠成功地治疗扭转型室速。患者女性,37岁,主诉胸痛,继之心跳停止。家人发现患者无反应,但十分钟内未行复苏努力。急诊人员检查时无脉搏、呼吸停止,心电图示室颤、心脏静止及自主性室性心律。立即采取气管插管,心肺复苏术,去颤,并应用阿托品、肾上腺素、纳洛酮、补 Sudden death in the heart, 75% to 85% due to ventricular tachycardia and ventricular fibrillation. Torsades ventricular tachycardia is a transient arrhythmia between ventricular tachycardia and ventricular fibrillation. In sudden cardiac death, the incidence of torsed ventricular tachycardia is as high as 32%. This article reports the successful treatment of torsades de pointes in 1 case with phenytoin sodium. Female patient, 37 years old, complains of chest pain, followed by heartbeat. The family found that the patient did not respond, but failed to recover within 10 minutes. Emergency personnel check without pulse, stop breathing, ECG-ventricular fibrillation, cardiac arrest and autonomous ventricular rhythm. Immediate tracheal intubation, CPR, tremor, and the application of atropine, epinephrine, naloxone, make up
