A six-month-old child is being evaluated for a ventricular septal defect. Which of the following murmurs would you most expect on physical examination?

A. Continuous machine-like murmur

B. Crescendo–decrescendo systolic ejection murmur

C. Holosystolic murmur

D. Late diastolic murmur

E. Systolic murmur with a midsystolic click






why? please explain it ? Thanks


hi...murmur means...abnormal flow thro normal structure or normal flow thro abnormal structure....flow occurs when there is considerable pressure gradient..say in systole..LV Pr IS 120mm Hg..RV Pr is 25mm Hg..BUT IN DIASTOLE BOTH HAVE AROUND 0 mm Hg....implies murmur in VSD will be systolic..and pan systolic..becos pressure gradient exists thro out systole
