본 증례는 흉통과 심계항진을 호소한 환자에서 우관상동맥 근위부에 위치한 심근고리가 우연히 진단되었던 환자로서 심방세동 및 완전 방실 차단이 동반되었던 환자이었다. Myocardial bridge is characterized by systolic compression of a portion of the coronary artery by a segment of overlying myocardium, commonly involves the middle segment of left anterior descending coronary artery. We present a case report of coronary angiographic evidence of systolic short segmental constriction in the proximal right coronary artery (RCA). A 42 year-old man presented with atypical chest discomfort and palpitation. Electrocardiography showed complete AV block with complete AH block on intracardiac electrocardiogram. Myocardial SPECT imaging demonstrated a mild reversible anterior and inferior wall perfusion defect. Diagnostic coronary angiogram revealed short segmental myocardial sling with wedge-shaped systolic compression in the proximal RCA.(Korean J Med 62:675-679, 2002) KCI Citation Count: 0
