What is a Treadmill Test (TMT) or Stress Test, and what does it tell about heart health?

In non-technical language, a Treadmill Test (TMT) or Cardiac Stress Test is a controlled test where you walk on a treadmill while being connected to the ECG leads. While the speed and grade on the treadmill increase gradually, physicians will monitor how your heart rate and rhythm, as well as your blood pressure, respond to exertion. https://www.saaoldelhi.com/blogs/what-is-a-treadmill-test-tmt-or-stress-test-and-what-does-it-tell-about-heart-health/
