Insights
Most childhood heart murmurs are innocent and not indicative of serious heart problems. These benign murmurs are common in healthy children, particularly after infancy, and require context from the child
Area of Science:
- Pediatric Cardiology
- Diagnostic Medicine
- Child Health
Background:
- Heart murmurs are frequently detected during routine physical examinations in children.
- Distinguishing between innocent and pathological murmurs is crucial for accurate diagnosis and management.
Purpose of the Study:
- To clarify the nature of heart murmurs found in healthy children.
- To differentiate benign murmurs from those indicative of cardiac dysfunction or defect.
Main Methods:
- Review of pediatric physical examination findings.
- Analysis of historical context and associated symptoms.
- Correlation of murmur discovery with age and health status.
Main Results:
- Innocent or benign murmurs are common in children, especially between ages 3-6 and in young adulthood.
- Pathological murmurs associated with heart defects are most prevalent in infancy.
- Murmur evaluation must integrate patient history and other physical findings.
Conclusions:
- The majority of heart murmurs identified in children are benign.
- Early identification and contextual assessment are key to avoiding unnecessary concern for cardiac dysfunction.
Abstract:
Many healthy children may be found to have a murmur on physical exam. Whether this murmur is discovered at a routine health maintenance visit or as a result of a focused exam on a child with illness, it is just one finding and must be considered in the context of the child's history and other physical exam findings. Murmurs associated with heart defect or dysfunction occur most often in infancy. Most murmurs discovered in children, especially after infancy, between ages 3 to 6 and in young-adulthood, are innocent or benign murmurs and less likely a symptom of cardiac dysfunction or defect.

01:15Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...

Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
