What is cardiomyopathy?

Cardiomyopathy is a diminished effectiveness of the heart muscle (myocardium).

Diagnosis of Cardiomyopathy

Cardiomyopathy diagnostic methods include EKG, chest x-ray, MRI, echocardiogram, blood tests and auscultation (see below).

Auscultation of Cardiomyopathy

This is auscultation of cardiomyopathy taken at the apex. Note that S1 is softer than normal due to decreased LV contractility. S2 is normal at the Apex. An S3 is present due to left ventricular failure. A rectangular, medium-pitched murmur of mild mitral insufficiency is due to a dilated mitral valve annulus.
