Cardiac dystrophy

Myocardial muscle (cardiac muscle) A muscle tissue composed of cardiac muscle cells. Broadly defined cardiomyocytes include the specially differentiated cardiomyocytes that make up the sinoatrial node, intraatrial bundle, atrioventricular junction, atrioventricular bundle (that is, the Heath bundle), and Purkinje fibers, as well as general atrial and ventricular muscles. Working cells. The first five make up the cardiac pacing conduction system. They contain very little or no myofibrils, so they have no contractile function; however, they have autonomy and conductivity, and are the functional basis of cardiac autonomic activity; Both are contractile and are the functional basis of cardiac diastolic activity. Myocardial tissue nutritional disorders are more common in cardiomyopathy.
