Cardioverter A machine that restoration of the heart's rhythm to normal by electrical countershock. The study of the heart. Cardiopathy Any disease of the heart. Congestive Heart Failure A weakness of the heart that causes an insufficient blood supply which results in an excessive build up body fluids in the body or the lungs. The area of that heart that is weak determines the location of the build up of body fluids.
Fluids build up in the lower limbs and abdomen when the right side of the heart is weak.
If the left side of the heart is weak, the lungs fill up with fluid. Without treatment, fluid build up in the lungs results in suffocation, or the literal drowning in one's own body fluids. Coronary Artery Disease A narrowing of the coronary arteries that reduces blood supply to the heart muscles. The most common cause is arteriosclerosis. In severe cases, the lack of blood supply may result in damage to the heart muscles.
