Cardiac Tests
 
ECG
  This Measures the electric activity of the heart. A change in the ECG pattern can be indicative of presence of heart disease.
   
Stress Test
  The Stress test provides more information than a rest ECG since the oxygen demand on your heart is greater while exercising.
   
Thallium Stress Test/ Nuclear Medicine Stress Test
  1) It is a regular Stress Test, but a dye is injected into the heart and pictures are taken of the heart, before and after the Stress Test.
  2) This can detect areas of the heart muscle that have been damaged by a heart attack and areas that are not getting enough oxygen due to      partial blockages of the coronary arteries.
   
Echocardiography
  This tests the pumping action of the heart. It also helps to study the motion of the heart valves that control the flow of blood in and out of the heart. During the test, sound waves are bounced off the surface of the heart to produce a picture on the screen.
   
Coronary Angiography
  An angiogram is a specialized X-ray test that monitors blood flow in the arteries. The test can diagnose coronary artery disease, which causes heart arteries to narrow from fat or calcium build-ups on artery walls.
