Heart Muscle

Heart MuscleHeart walls are muscles that rhythmically accumulate about 100,000 times a day. If the heart muscle weakens, the heart rate (pulse) decreases, which leads to a poor circulation.
There are many forms of heart muscle disorders (cardiomyopathy). Muscle fibers may be inflammed or swollen, and muscle may weaken due to internal chemical changes. In some cases the disease is limited to the heart, and in others the heart is only one of the affected organs. Cardiomyopathies are generally not as common as other cardiac diseases.
