Which statement best describes innocent murmurs in children?

• A. The murmur is holosystolic
• B. Prompt referral to a cardiologist is indicated
• C. A precordial thrill is present
• D. The murmur is low intensity, grade 1-3

Answer: (C)

Innocent murmurs in children are a normal finding and do not indicate heart disease. They are typically systolic, short in duration, and softly heard, usually graded as I or II (low intensity). They often occur without any accompanying abnormal findings such as a thrill, abnormal pulses, or signs of congestive heart failure, and they may vary with position or disappear with age. The hallmark of an innocent murmur is that it is quiet and transient, not loud or structural in origin. A holosystolic murmur would raise concern for an underlying defect like a VSD or MR; a palpable precordial thrill would indicate a louder, more concerning murmur due to significant flow or structural abnormality; and while many innocent murmurs do not require referral, red flags or persistent findings would prompt further evaluation. Therefore, describing the murmur as low intensity and grade 1-3 best fits the benign nature of innocent murmurs.
