Complete Atrioventricular Block and Cardiopulmonary Involvement in Rapidly Progressive Systemic Sclerosis

Abstract The heart and lung are target organs in systemic sclerosis (SSc) and similar symptoms (dyspnea and cough) may make the differential diagnosis between the two lesions difficult. In addition, complete atrioventricular block (CAVB) is a rare complication of this disease. This case report is about a patient with SSc and pulmonary fibrosis who was admitted to the emergency room with CAVB, heart failure (HF) and progressive worsening of the underlying disease.

【摘要】系统性硬化症（systemic sclerosis, SSc）可累及心、肺两大靶器官，其引发的相似临床症状（呼吸困难与咳嗽）易导致二者病变的鉴别诊断困难。此外，完全性房室传导阻滞（complete atrioventricular block, CAVB）是该病的罕见并发症。本病例报告的患者为系统性硬化症合并肺纤维化者，因出现完全性房室传导阻滞、心力衰竭（heart failure, HF）及基础疾病进行性加重而被收入急诊室。
