This collection is designed to offer veterinarians a library of heart sounds with known clinical diagnoses. These sounds can be used as a comparison tool for practitioners. Following patient auscultation in the clinical setting, practitioners can listen to the heart sounds below to help identify those encountered in practice.
These recordings, taken with an electronic stethoscope on actual patients, may include some background noise. The sounds have not been modified; headphones are recommended for optimal listening. Unless specified, all sounds are from canine patients.
