[|Human|] Hello SirI am Jatinder Kumar and having Chest pain from Last few Months. I have Done 2 Time ECHO And 2 Times TMT Test. Impression of TMT in First Time PTA Achived THR and Second Time i have Shortness of breath Problem and TMT Reschudle Then Impression of TM is PTA Did not Achived THR. What is Difference of These Test. Heart Target Rate 89 % in First TMT and 79% in second TMT. Please Give me Best Suggestion.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Our heart rate increases with exercise. This is normal for every one. Depending on persons' height, weight, target heart rate (THR) is decided by TMT machine. If we achieve THR without getting breathless or rising BP or abnormal ECG then out TMT is good. But if we fail to achieve THR due to breathlessness or accelerated hypertension or ECG changes means our TMT is not good, and we need angiography to rule out coronary artery disease (CAD). Since your TMT was stopped due to breathlessness and hence THR was not achieved, possibility of CAD is more in your case. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
