[|AI|]  Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you should consult cardiologist and get done1. ECG2. 2d echo3. Stress test (trade mill test)To rule out cardiac cause. There is high possibility of cardiac cause in your case, so we need to rule out this first. You are having palpitations, breathlessness on exertion (uphill walking) and age more than 50, all these favor cardiac cause more. So get done above-mentioned investigations first and rule out cardiac cause. So consult cardiologist and discuss all these.
