Second Heart Sound with Fixed Splitting | Auscultation #22 | Lesson with Audio

patient position during auscultation
The patient was supine during auscultation.

Description

This example shows fixed splitting of the second heart sound. The second heart sound remains unchanged through inspiration and expiration at sixty milliseconds. Fixed splitting of the second heart sound (along with murmurs) indicates the presence of an Atrial Septal Defect, a congenital heart defect in which the intra-atrial septum is incomplete resulting in a hole between the left and right atria. The murmurs have been eliminated in this lesson so that you can concentrate on the fixed splitting of the second heart sound. In a later lesson you will hear the fixed splitting of S2 along with the murmurs of Atrial Septal Defect.
