Which heart murmur is often associated with innocent flow murmurs in children?

The systolic ejection murmur is commonly associated with innocent flow murmurs in children due to its characteristics and occurrence during the cardiac cycle. Innocent murmurs, also referred to as functional or physiological murmurs, are typically found in well-functioning hearts of children and are often benign in nature. They commonly occur during systole, which is when blood is ejected from the heart through the valves into the arteries.

These murmurs are produced by the increased velocity of blood flow, especially in conditions where blood flow is rapidly accelerated through normal structures, such as the aortic or pulmonary valves. The systolic ejection murmur is usually characterized by a soft, short, and often vibratory sound that occurs between the first heart sound (S1) and the second heart sound (S2), without any accompanying pathological signs.

Innocent murmurs are prevalent in the pediatric population and generally dissipate as the child grows older, making them a common and reassuring finding in children's assessments. This is in contrast to other types of murmurs, like diastolic murmurs or holosystolic murmurs, which suggest underlying cardiac conditions and are not considered innocent. A continuous murmur indicates a more complex hemodynamic issue, such as a
