Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, either primary or secondary to another cardiac or systemic disease. There is a congenital form which occurs in calves and an acquired form. Skeletal muscle is usually affected concurrently. Restrictive cardiomyopathy is rare in cattle but any disease that leads to fibrosis of the cardiac muscle can result in restrictive cardiomyopathy.

Cardiac murmurs

Cardiac murmurs are audible sounds that occur during the cardiac cycle and result from turbulence in laminar blood flow or vibration of certain cardiac structures (chordae). Cardiac murmurs are distinct from the normal heart sounds caused by passive valve closure and should also be distinguished from systolic clicks, gallop rhythms, and normal and abnormal respiratory sounds. Murmur analysis by auscultation or by examination of a phonocardiogram can provide useful diagnostic information.

Electrocardiogram (ECG)

An electrocardiogram (ECG) is a recording of the changes in the electrical potential difference of the heart, which occur during depolarization and repolarization of the myocardial cells and are plotted against time. The body itself is a conduction system therefore this activity can be monitored from electrodes placed on the surface.
