The coronary slow flow phenomenon (CSFP) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. Although the relation between the CSFP and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the CSFP and the conduction system disorder. In this case report, we describe a patient with the CSFP presenting with complete heart block (CHB). The patient was a middle-aged woman with a history of diabetes, hypertension, and prior Coronary Care Unit admission presenting with dizziness, lightheadedness, and presyncope. Electrocardiography revealed CHB with no significant ST-T change. Cardiac enzymes and other routine lab tests were normal. The patient underwent temporary pacemaker implantation. Due to persistent atrioventricular block and suspicion of ischemic heart disease, she underwent coronary angiography, which showed the CSFP and no significant stenosis. The patient was discharged after permanent pacemaker implantation and remained asymptomatic at 3 months' follow-up.
冠状动脉慢血流现象（CSFP）的特征是在无阻塞性冠状动脉疾病的情况下冠状动脉血流延迟。虽然此前已有关于CSFP与心肌缺血关系的报道，但对于CSFP与传导系统紊乱之间的关系尚无了解。在本病例报告中，我们描述了一名患有CSFP并伴有完全性心脏传导阻滞（CHB）的患者。该患者为中年女性，有糖尿病、高血压病史，既往曾入住冠心病监护病房，此次因头晕、头重脚轻和先兆晕厥就诊。心电图显示为CHB，ST-T无明显改变。心肌酶及其他常规实验室检查均正常。患者接受了临时起搏器植入术。由于持续性房室传导阻滞且怀疑有缺血性心脏病，她接受了冠状动脉造影，结果显示为CSFP且无明显狭窄。患者在植入永久性起搏器后出院，随访3个月时仍无症状。
