Although between 50% and 85% of children may have a heart murmur, most heart murmurs are innocent. Murmurs can occur because of children’s high cardiac output and small vessels, branching at acute angles, which promote turbulent flow. Innocent murmurs can be described according to seven characteristics, but not all murmurs adhere to these rules.

Diastolic murmurs begin with or after the associated component of S 2 and end at or before the subsequent S 1. Continuous murmurs are not confined to either phase of the cardiac cycle but instead begin in early systole and proceed through S 2 into all or part of diastole. The accurate tim-ing of heart murmurs is the first step in their ...

•Most murmurs decrease their intensities after Valsalva maneuver (i.e. with decreased preload) with the exception of the murmurs of hypertrophic cardiomyopathy (sub-aortic left ventricular outflow obstruction) and mitral valve prolapse (MVP). As a general rule increasing preload increases flow

•Valsalva –Straining increase intrathoracic pressure and decreases venous return to the heart –Results in heart rate increase and decrease intensity of most systolic murmurs –Murmur related to hypertrophic cardiomyopathy increases as obstruction worsens with lower stroke volume

Low-pitched murmurs are heard best with a bell, and high-pitched murmurs are heard best with a diaphragm. Some frequency ranges are inaudible by the human ear, and thus palpating for thrills is another means of detecting murmurs.
