TMT or Treadmill Test is a stress test, used to determine how well your heart responds during times when it’s working its hardest. During the test, you’ll be asked to exercise — typically on a treadmill — while you’re hooked up to an electrocardiogram (ECG) machine. This allows your doctor to monitor your heart rate.
ECG or Electrocardiography is a test conducted to record the status of your heart. It gives information on the functioning of your heart and is one of the most commonly used tests to detect a heart attack or missing beats.
