Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should definitely rule out heart diseases for your symptoms. So better to consult cardiologist and get done blood pressure monitoring, ECG, 2d echo and stress test (trade mill test). If all these are normal then no need to worry about heart diseases. Sometimes undiagnosed stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relaxed and calm. Consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
