Heart murmur is the most common reason for a referral to a pediatric cardiologist. Virtually all children have a heart murmur during their childhood. Less than 1% of murmurs are pathological in children. Innocent/functional heart murmur is the most common type of heart murmur. There are multiple theories proposed to identify etiology of innocent heart murmur with varying consensus, but everybody agrees that innocent heart murmur does not carry any morbidity or mortality risk. Even today, heart murmur is associated with high physician uncertainty and parental anxiety. Extensive cardiac evaluation for such a benign finding is also associated with high health care utilization and cost. This article attempts to review this long-known finding which continues to remain a diagnostic challenge.
心脏杂音是转诊至儿科心脏病专家的最常见原因。实际上，所有儿童在童年时期都会出现心脏杂音。儿童中不到1%的杂音是病理性的。无害性/功能性心脏杂音是最常见的心脏杂音类型。关于确定无害性心脏杂音病因提出了多种理论，共识不一，但大家都认为无害性心脏杂音不会带来任何发病或死亡风险。即使在今天，心脏杂音仍会导致医生高度不确定和家长焦虑。针对这样一个良性发现进行广泛的心脏评估也会导致高医疗利用率和高成本。本文试图对这一早已为人所知但仍然是诊断难题的发现进行综述。
