Final answer:
Auscultation findings in chronic mitral regurgitation include a holosystolic murmur, an S3 heart sound, and possibly an S4 heart sound.
Step-by-step explanation:
When auscultating a patient with chronic mitral regurgitation, certain findings can be observed. One common finding is a heart murmur, which is an unusual sound caused by the turbulent flow of blood. The murmur associated with chronic mitral regurgitation is usually holosystolic, meaning it occurs throughout systole, and is best heard over the apex of the heart. It is typically described as a blowing or high-pitched sound. Additionally, other auscultatory findings may include an S3 heart sound, indicating volume overload of the ventricle, and possible S4 heart sound, indicating left ventricular hypertrophy or stiffness.
