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.
TMT test +ve for reversible ischaemia, normal BP response, good exercise tolerance, LVEF=65%. What does this mean for the patient? Eco cardiogram parameters are all within normal range except observation-Aortic valve thickened. Aortic sclerosis without any evidence of aortic stenosis.
My father s TMT test report says CARDIAC STRSS ANALYSIS NEGATIVE FOR INDUCIBLE MYOCARDIAL ISCHEMIA AT AVERAGE WORK LOAD 93% OF MAXIMUM HEART RATE RESPONSE . But a Cardiologist Interventional has written POSITIVE TMT for inducible ischemia. Can you please clarify what this means and action that needs to be taken?
Hi, I am 43 Yrs, LDL - 163/ HDL - 62, No Sugar, No Triglyceride, Slim, smoker. TMT report says positive, however one cardiologist looked at the graph saying the abnormality of curve did not susain more than 6 seconds and hence TMT is negative. What does this mean?
