Evaluation of heart sounds and murmurs in children
Insights
Pediatric cardiovascular evaluation relies on auscultation, a routine focusing on heart sounds, clicks, and murmurs. Proper identification aids in diagnosing congenital heart disease and understanding cardiac conditions.
Area of Science:
- Pediatric Cardiology
- Clinical Auscultation
- Diagnostic Techniques
Background:
- Auscultation is fundamental for pediatric cardiovascular assessment.
- A systematic approach is crucial for accurate evaluation.
- Understanding normal and abnormal heart sounds is key.
Purpose of the Study:
- To outline a routine for pediatric cardiovascular auscultation.
- To emphasize the diagnostic significance of specific sounds.
- To provide a framework for characterizing cardiac murmurs.
Main Methods:
- Performing auscultation following a structured routine.
- Systematically identifying the four heart sounds in their usual locations.
- Listening for clicks (systolic, pulmonary, aortic, midsystolic).
- Detecting and characterizing murmurs (systolic, diastolic, continuous).
Main Results:
- The second heart sound holds significant diagnostic value, especially in congenital cyanotic heart disease.
- Clicks can occur at different points in the cardiac cycle.
- Murmurs require detailed characterization including timing, intensity, frequency, location, and radiation.
Conclusions:
- A routine auscultation process enhances pediatric cardiovascular evaluation.
- Detailed characterization of heart sounds, clicks, and murmurs is essential for diagnosis.
- This systematic approach aids in identifying congenital heart disease and other cardiac abnormalities.
Abstract:
Auscultation is the core of pediatric cardiovascular evaluation and should be performed according to a routine. The four heart sounds should be sought in order at their usual locations, with particular attention to the second sound because of its important diagnostic role in congenital cyanotic heart disease. The next sounds to listen for are clicks, which can be systolic, pulmonary, aortic, or midsystolic. Finally, murmurs should be sought in systole and then diastole. Besides being identified as systolic, diastolic, or continuous, murmurs should be characterized according to their relationship with the first and second heart sounds, intensity, frequency, and maximum location and radiation.

Heart 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) valves at the...

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.
