Some heart problems only show up when the heart is working hard. A TMT has you walk on a treadmill at gradually increasing speed and incline while your ECG, heart rate, and blood pressure are monitored continuously. This reveals blockages or rhythm problems that a resting ECG can miss, and it's a standard way to check whether it's safe for you to return to normal physical activity after a cardiac event.
How It Works
- 1Sensors are placed on your chest to monitor ECG throughout the test.
- 2You walk on a treadmill that gradually increases in speed and incline in stages.
- 3Heart rate, rhythm, and blood pressure are tracked continuously until you reach a target heart rate or report symptoms.
- 4The test stops and you're monitored during recovery to see how quickly your heart returns to normal.
When it's usually needed
- Chest discomfort that occurs specifically during exertion
- Evaluating fitness to resume exercise after a cardiac event
- Assessing unexplained breathlessness on exertion
