快速心率依赖型阵发性房室传导阻滞(AVB)常发生在伴有单支传导阻滞的器质性心脏病基础上,发生对侧的位相阻滞而出现Ⅲ°AVB。我院收治1例主动脉关闭不全伴快速心率依赖型阵发性AVB,现报告如下:病例介绍患者,女,37岁,因发作性意识障碍于1985年6月入院。检查:脉率42次,血压90/54,神清,颈动脉搏动明显,水冲脉,心界向两侧扩大,心尖搏动在第六肋间左锁骨中线外1cm,心率42次,主动脉瓣区闻及Ⅲ°喷射收缩期杂音及Ⅲ°舒张期杂音,周围血管征(+)。胸片示
Rapid heart rate-dependent paroxysmal atrioventricular block (AVB) often occurs on the basis of organic heart disease with single branch block, with contralateral phase retardation leading to Ⅲ ° AVB. Our hospital admitted to a case of aortic insufficiency with rapid heart rate-dependent paroxysmal AVB, are as follows: Case Description The patient, female, 37 years old, was admitted to hospital in June 1985 because of episodic disturbance of consciousness. Check: pulse rate 42 times, blood pressure 90/54, Shen Qing, obvious carotid pulsation, water pulse pulse, the heart bound to both sides of the enlarged apex beat in the sixth intercostal left subclavian midline 1cm, heart rate 42 times, aorta Flap valve smell and Ⅲ ° injection systolic murmur and Ⅲ ° diastolic murmur, peripheral vascular sign (+).
