Cardiac Library
Evaluation of the cardiovascular system involves more than simply listening through a stethoscope. Thorough evaluation also requires visual assessment of potential clinical signs, palpation to assess pulses and thrills, and clinical reasoning when evaluating patient history and signalment. This resource can aid clinicians seeking to elevate their knowledge of cardiac assessment, diagnosis, and management.

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.
