患者女性,31岁。因间断出现心悸、低热、盗汗伴全身关节酸痛、乏力一月而于1988年5月28日入院。查体:血压14.3/9.1kPa(110/70mmHg)。发育营养一般。心界不大,心率72次/分,心律齐,心音低钝,心尖部可闻及Ⅰ～Ⅱ级收缩期吹风样杂音,无奔马律和心包摩擦音。实验室检查:ASO800u,ESR30mm/h,ECG示P—R间期0.22s、轻度ST—T改变。胸片示双肺纹理增粗,升主动脉无扩张,各房室无扩大,心胸比率0.52。次日下午在X光透视下穿刺右股静脉将三根导管电极分别置于高位右房,三尖瓣环及右室心尖部,测定窦房结功能和描记希氏束电图。术中病人突然发生心房纤颤,静脉注射心律平69mg后当即出现窦性停搏、室性逸搏性心律,心率30～40次/分。病人大汗淋漓、张口呼吸、血压下降,立即进行心房起搏。半小时后恢复为窦性心律,
Patient female, 31 years old. Due to intermittent palpitations, fever, night sweats with systemic soreness, fatigue in January and was admitted to hospital on May 28, Physical examination: blood pressure 14.3 / 9.1kPa (110 / 70mmHg). Developmental nutrition in general. Heart, heart rate 72 beats / min, heart rate Qi, heart sound low blunt, apex can be heard and Ⅰ ~ Ⅱ systolic hair-like murmur, no gallop and pericardial friction fricative. Laboratory tests: ASO800u, ESR30mm / h, ECG showed P-R interval 0.22s, mild ST-T changes. Chest radiograph showed thickening of lungs, ascending aorta without expansion, no atrioventricular antrum, cardiothoracic ratio 0.52. The next afternoon under the X-ray puncture of the right femoral vein will be three catheter electrodes were placed in the high right atrium, tricuspid annulus and right ventricular apex to determine the function of the sinoatrial node and Described His bundle. Intraoperative patients with sudden onset of atrial fibrillation, intravenous rhythm immediately after 69mg sinus arrhythmia, ventricular escape rhythm, heart rate 30 to 40 beats / min. Patient sweating, mouth breathing, blood pressure, immediately atrial pacing. Half an hour later returned to sinus rhythm,
