By following these steps, healthcare providers can chart heart sounds with precision and accuracy, contributing to a comprehensive assessment of the patient’s cardiovascular health.
A phonocardiogram (PCG) plots recordings of a heart sound and murmur during the cardiac cycle, and analysis of a PCG signal is useful in detecting abnormalities of a heart by using time-frequency analysis and classifications of the heart signals (Milani, Emeroylariffion, Silva, & Nanayakkara, 2021).
The first heart sound (S 1) contains two components: the mitral valve closure sound (M 1) and the tricuspid valve closure sound (T 1). The second heart sound (S 2 ) contains two components: the aortic valve closure sound (A 2 ) followed by the pulmonary valve closure sound (P 2 ).
Most children with a small PDA have normal first and second heart sounds and peripheral pulses. A grade 1 to 3/6 continuous murmur is heard best in the upper left sternal border (see table Heart Murmur Intensity). The murmur extends from systole to beyond the second heart sound (S2) into diastole and typically has a different pitch in systole ...
The clinician focuses attention sequentially on each phase of the cardiac cycle, noting each heart sound and murmur. Intensity, pitch, duration, and timing of the sounds and the intervals between them are analyzed, often providing an accurate diagnosis.
