Can auscultation diagnose heart disease by heart beating?

Auscultation heart beat can help screen for heart disease, but can not directly confirm the diagnosis.

Auscultation heart beat is a physical examination means, you can listen to the heart beat speed, sound intensity, abnormal sound, but also can count the rhythm, if found abnormal, suggesting that there may be heart disease. But the diagnostic value of auscultation is limited, because some heart diseases may not lead to changes in heart rhythm, heart sounds, etc., so auscultation may not be abnormal. Generally, heart disease is not judged solely according to the results of auscultation, but also need to further do ECG, cardiac ultrasound and other examinations.
