患者男,50岁,于1991年6月20日晨6时突感胸闷、心慌、气短,随即晕厥数秒钟后清醒.在单位医务所经一般处理无效,送湖州市第一医院急诊.患者平时体健.无心脏病病史、体检:神清,呼吸22次:分,血压16/10kpa.无紫绀,颈静脉无怒张,两肺呼吸音清,心界叩诊正常范围、心率72次/min.频发早搏时呈二联律,未闻杂音.心电监护(摸拟V_5导联)示频发室性早搏.呈二联津时伴多形性室性心动过速,室早联津间距为260～300ms,其前无长间歇.室连QRS波幅及方向不一致.围绕轴心上下扭转,频率300次/分;窦性心津时Q-T间期为0.32s.最短的空速QRS波仅连续出现14次,最长持续69s,40s后蜕变为室颤.多形室速持续数次或数秒者均能自行终止或拳击后终止,最长一次经心外按压和异搏定治疗才终止.
Male, 50 years old, at 6:00 on June 20, 1991 suddenly felt chest tightness, palpitation, shortness of breath, and then sobbed a few seconds after the onset of syncope. In general, the unit medical office invalid, sent to Huzhou City First Hospital emergency. No history of heart disease, physical examination: Shen Qing, breathing 22 times: points, blood pressure 16 / 10kpa. No cyanosis, no jugular vein engorgement, lung breath sounds clear, heart percussion normal range, heart rate 72 beats / min. Frequent premature beating was two law, no noise .Electrocardiogram monitoring (simulation V_5 lead) showed frequent premature ventricular contractions .Two tianjin with pleomorphic ventricular tachycardia, room early Tianjin Jin distance For 260 ~ 300ms, there is no long intermittent before .Electroventricular QRS amplitude and direction inconsistent around the axis up and down the reverse, the frequency of 300 beats / min; sinus QT period was 0.32s. The shortest airspeed QRS wave only appeared continuously 14 times, the longest sustained 69s, after 40s transformed into ventricular fibrillation polymorphic ventricular tachycardia continued for several or a few seconds can be terminated on their own or after the boxing, the longest time by extrahepatic pressure and verapamil treatment was terminated.
