患者,女,38岁.因反复心慌气短8年加重2d 昏厥2次,于1986年12月17日以病毒性心肌炎Ⅲ°房室传导阻滞、心源性脑缺氧入院。8年来间断心悸、气短,未曾确诊。查体:血压13.3/8kPa(100/60mmHg),心率52次/min.眼球稍突出(?)皮肤潮湿多汗,心界向左下扩大,心尖区可闻及Ⅲ级收缩期杂音,第一心音亢进,两肺呼吸音清晰,腹部(-)。入院时心电图示:Ⅲ度房室传导阻滞。3d 后心电图出现房(?)与Ⅱ度房室传导阻滞交替。心脏B 超示:左房扩大(47×50mm,前后径45mm),右室稍增大(36×70mm),余房室内径正常。心电向量图大致正 Patients, female, 38. Due to repeated palpitation shortness of breath 8d aggravate 2d fainting twice, on December 17, 1986 with viral myocarditis Ⅲ ° atrioventricular block, cardiogenic cerebral hypoxia admission. 8 years, continuous heart palpitations, shortness of breath, has not been diagnosed.
