Echocardiography or echo, is actually colored ultrasound of the heart, a painless test that gives a moving picture of your heart. The test gives information about the size of your heart and how well your heart’s chambers and valves are working. Echo also can be done to detect heart problems in infants and children. The test also can identify areas of heart muscle that aren’t contracting normally due to poor blood flow or injury from a previous heart attack. In addition, a type of echo called Doppler ultrasound shows how well blood flows through the chambers and valves of your heart. Echo can detect possible blood clots inside the heart, fluid buildup in the pericardium (the sac around the heart), and problems with the aorta. The aorta is the main artery that carries oxygen-rich blood from your heart to your body.


In TMT, an ECG is done while you are doing exercise. In this test, the patient walks on a treadmill as per the protocol of the test. Most often, it is done in healthy individuals as a preventive check up or in a post myocardial infarction patient. It is a test used to induce provocable myocardial ischemia for diagnostic evaluation of coronary artery disease.
