2D Echo, TMT, PFT
One must remember that the ECGs are taken at rest when the heart is beating at its lowest rate. In some of cases the patient would also agree that at the time of rest there is no pain in the chest, the angina symptoms would only come when they increase the heart rate, while doing some physical exertion like walking. In this condition,where we need a TMT test.
The patients might gradually increase their heart rate, thus increasing the blood requirement of the heart muscles. Simultaneously ECG records are taken.
