<s>[INST] Dear Sir I had experienced sweating and some easiness on few occassions in last 2-3 months. On investigations, the ECG had shown variations. But then I was able to withstand TMT for about 7-8 minutes. When I experience the above symtoms, my pulse rate goes up to about 95-100. The BP rate is about 95-97 on lower side to 145-150 on the higher side. After some time it comes back. The pulse rate falls back to about 70. BP too ranges back to 85-125 or so. I don t take any medicines for BP. The sweating normally occurs at night sometime late in my sleep at 2.30 AM or even 4 AM. Please advice. [/INST] See TMT has a sensitivity rate of only 65-70% depends on the accuracy of sensors used in machine your symptoms can be because of angina also so I would suggest you to go for a 2d echo it observes the motion of wall of heart and if there is any regional motion wall abnormality in that case it will be revealedconbined together echo and TMT has a sensitivity rate of more than 80%stress thallium is also a non-invasive test which has a sensitivity rate if about 97%, so you can go for these test to get a diagnosis gastritis acid peptic disease anxiety can also bring about the same symptoms!!! </s>
