Pet Diastolic Murmur Symptom Guide | What to Watch For and When to Seek Care
Understand possible causes of Diastolic Murmur and key home observations
A diastolic murmur heard at rest is a finding that should be observed. Record frequency, persistence, and changes to support evaluation.
What this symptom means clinically
A diastolic murmur is a sound caused by turbulent blood flow during ventricular relaxation, or diastole. It is usually associated with abnormal valve closure, valve regurgitation, or altered intracardiac blood flow pathways. This type of murmur reflects pressure gradients or blood flow instability during diastole, and its pitch, timing, and location help characterize the source.
🐱 In cats
Clear diastolic murmurs are less common in cats, are often quiet, and require careful auscultation in a calm environment. Causes may involve valve closure function or congenital blood flow abnormalities.
🐶 In dogs
In dogs, diastolic murmurs vary in location and sound quality and may relate to great vessel valves or changes in cardiac chamber pressures. They may be easier to detect in specific cardiac areas.

Possibly Related Conditions
Conditions owners commonly find associated with this symptom — tap to learn more.
Aortic Stenosis
Structural or electrical cardiac abnormalities impair pump function. This cardiac dysfunction manifests as diastolic murmur.
Atrioventricular Valve Dysplasia
Cardiac pathology impairs contractility, rhythm, or valve function. This cardiovascular dysfunction manifests as diastolic murmur.
Atrioventricular Valvular Stenosis
Heart disease reduces cardiac output and tissue perfusion. The circulatory compromise presents as diastolic murmur.
Endocarditis, Infective
Structural or electrical cardiac abnormalities impair pump function. This cardiac dysfunction manifests as diastolic murmur.
Patent Ductus Arteriosus
Cardiac pathology impairs contractility, rhythm, or valve function. This cardiovascular dysfunction manifests as diastolic murmur.
Sepsis and Bacteremia
Sepsis-induced myocardial depression and vasodilation impair cardiac output. This cardiovascular compromise manifests as diastolic murmur.
