Cardiology. Restrictive cardiomyopathy (RCM) is a form of cardiomyopathy in which the walls of the heart are rigid (but not thickened). [2][3] Thus the heart is restricted from stretching and filling with blood properly. It is the least common of the three original subtypes of cardiomyopathy: hypertrophic, dilated, and restrictive.
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1] An irregular heart beat and fainting may occur. [1]
Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure. [1][5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle ...
Specialty. Cardiology. Kussmaul's sign is a paradoxical rise in jugular venous pressure (JVP) on inspiration, or a failure in the appropriate fall of the JVP with inspiration. It can be seen in some forms of heart disease and is usually indicative of limited right ventricular filling due to right heart dysfunction.
Specialty. Cardiology. Arrhythmogenic cardiomyopathy (ACM) is an inherited heart disease. [1] ACM is caused by genetic defects of parts of the cardiac muscle known as desmosomes, areas on the surface of muscle cells which link them together. The desmosomes are composed of several proteins, and many of those proteins can have harmful mutations.
It is the most common form of non-ischemic cardiomyopathy and the dilatation of the heart results in larger chamber volumes & thinner myocardial walls, both of which decrease the ability to pump. Specific kinds of dilated cardiomyopathy are listed below, and other causes include Chagas disease , chemotherapeutic agents (e.g., doxorubicin ...
