Fixed Splitting Second Heart Sound | Lesson
Virtual Auscultation
The patient's position should be supine.
Lesson
When the separation of the two components of the second heart sound remains unchanged through inspiration, the split is called a fixed split.
The inability of the ventricles to change their volume with respiration causes the splitting. Fixed splitting of the second heart sound (along with murmurs) indicates the presence of heart disease or a heart defect.
