In a given case the diagnosis of such soft blowing murmurs calls for most careful judgment, for the evaluation of the type of murmur is of extreme importance as regards the subsequent treatment of the child.

Various diagnostic criteria have been proposed to aid in distinguishing between organic and functional murmurs. Briefly stated, they are as follows:

Time in Cycle.  —A functional murmur is almost invariably systolic, rarely diastolic, in time.
