###Human: Is flattened T wave something to be worried about? ###Assistant: Hello. Yes, there are changes in the ECG (attachment removed to protect patient identity). But, your evaluation is normal including echo and treadmill test. Now, the changes in the ECG are likely due to high BP and not any blockages. I guess you do not have any symptoms like chest pain or chest heaviness on exertion or during the treadmill test. So I do not think there is anything to worry about now. Is your blood pressure well controlled? You have to check your BP frequently, thrice a day at least for a week so as to know the pattern of BP. Have a low salt diet. It is important that gradually you quit smoking because smoking is much harmful than alcohol and alcohol occasionally is acceptable but not smoking. Hope this helps you and get back if you have any doubts. For more information consult a cardiologist online -->
