A patient in whom mixed connective tissue disease in association of Sjögren's syndrome had previously been diagnosed, experienced a syncopal attack. Electrocardiographic monitoring revealed periods of profound sinus bradycardia, sinus arrest with slow junctional escape rhythm, and first degree atrioventricular block during several episodes of dizziness. Complete right bundle branch block was a constant finding in this patient. Sinoatrial conduction time and sinus node recovery time were prolonged. Coronary heart disease was excluded by normal coronary arteriographic findings. This patient represents a rare case of cardiac involvement in mixed connective tissue disease.
一名先前被诊断患有混合性结缔组织病合并干燥综合征的患者发生了一次晕厥发作。心电图监测显示,在几次头晕发作期间,出现了严重窦性心动过缓、窦性停搏伴缓慢交界性逸搏心律以及一度房室传导阻滞。完全性右束支传导阻滞在该患者中持续存在。窦房传导时间和窦房结恢复时间延长。冠状动脉造影结果正常排除了冠心病。该患者代表了混合性结缔组织病累及心脏的罕见病例。
