Hi, You need not do TMT repeatedly. If during exercise you don’t have pain then there is nothing to worry Sometimes musculoskeletal pain mimic cardiac pain. But cardiac pain also comes out positive with ECG ECHO or TMT. For a 26 yrs Active person there is no need to do regular TMT TMT is a valid test bcz it is a dynamic stress test for heart while you walk. So if there is any demand- supply miss-match of blood to heart muscle it will be reflected in ECG.
