Diagnostic tests for heart conditions include electrocardiogram, stress test, echocardiogram, positron emission tomography scan and tilt table test options. Others include magnetic resonance imaging of the heart and cardiac CT scans, according to Johns Hopkins Medicine. These tests help determine and understand the complexity of a patient’s cardiovascular disease.
An electrocardiogram test records the electrical activity of the heart such as the speed of heart beat and its rhythm, states the National Heart, Lung and Blood Institute. Stress test monitors the hearts condition before and during exercise. It detects abnormal changes in the heart rate and rhythm. Echocardiogram, as reported by Johns Hopkins Medicine, uses sound waves to evaluate the heart’s chambers and valves. Doctors determine which of these tests is necessary based on the patient’s physical exam, medical and family histories.
