患者男、38岁,无明显诱因发作晕厥5年,先后黑朦或晕厥13次,因住院后各种检查阴性,故诊断为不明原因的晕厥。后在我院仍未查出晕厥原因,而行植入式Holter检查。住院时12导联心电图在Ⅱ,Ⅲ,aVF导联存在“早复极综合征”的表现(图1A),运动后该图形消失(图1B),半年后植入式Holter的随访记录证实患者存在多形性室速,进而推断其症状较重时的晕厥为室颤所致,进而诊断为“特发性室颤”(图1C),随后植入ICD治疗(图2)。
Male patient, 38 years old, no obvious incentive episode syncope 5 years, successively dark or fainted 13 times, due to various tests after the hospital was negative, so the diagnosis of unexplained syncope. After in our hospital has not yet detected the cause of syncope, and implantable Holter examination. The 12-lead electrocardiogram showed “early repolarization syndrome” in leads II, III and aVF during hospitalization (Fig. 1A), disappeared after exercise (Fig. 1B), and follow- Confirmation of pleomorphic ventricular tachycardia and subsequent extrapolation of syncope as a consequence of ventricular fibrillation were diagnosed as “idiopathic ventricular fibrillation” (Figure 1C) followed by ICD therapy (Figure 2) .
