Cardiac Sounds

Heart sounds (eg, pitch, volume, rate, rhythm) can provide a great deal of information about the condition of a patient’s heart. Being able to interpret what those sounds mean is a skill that requires practice. This section of the cardiac library provides audio clippings of heart sounds to help clinicians learn what to listen for.

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.

Vertebral left atrial size (VLAS) is an objective radiographic measurement that can help determine whether left atrial enlargement is present with suspected or diagnosed myxomatous mitral valve disease. Review how to calculate VLAS in dogs.
