Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should first rule out heart diseases like heart failure and coronary artery disease (CAD). You're all symptoms like chest pain on exertion, sweating, rapid heart rate, breathlessness etc. are commonly seen with heart diseases. So immediately consult cardiologist and get done 1. ECG 2. 2d echo 3. Stress test 4. Coronary angiography (if required). You will need cardiac supportive Chat Doctor.  Don't worry, you will be alright with all these. First diagnose yourself and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
