TMT - Treadmill Test -- Stress induced Electrocardiogram
TMT is the most widely used test in the diagnosis of ischemic heart disease
. It involves recording the 12-lead ECG before, during, and after exercise on a treadmill.
The test consists of a standardized gradual incremental increase in external workload while the patient's ECG, symptoms, and arm blood pressure are continuously being monitored. The test is discontinued upon evidence of chest discomfort
, severe shortness of breath
, dizziness, fatigue, ST-segment depression
of greater than 0.2 mV (2 mm), a fall in systolic blood pressure exceeding 10 mmHg, or the development of a ventricular tachyarrhythmia.
This test helps to discover any relation between exercise and chest discomfort and the typical ECG signs of myocardial ischemia
