D
Feedback:
Echocardiography is useful in the diagnosis and differentiation of heart murmurs, congestive heart failure, and the amount of blood each ventricle ejects (pumps out) with every heart beat. An electrocardiogram (ECG) provides essential information about the heart, including rate, rhythm, and the presence of certain disorders. The purpose of the stress test is to assess the severity of symptomatic and asymptomatic (without symptoms) cardiac disease. The electrophysiology study (EPS) provides valuable information about the electrical activity of the heart by locating the source of a dysrhythmia.
