Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you're all symptoms are mostly due to uncontrolled stress, anxiety and panic disorder. But better to rule out heart diseases like arrhythmia (rhythm disturbances in heart) because heart flutters are common with arrhythmia. So better to get done ECG, 2d echo and Holder monitoring (24 hours continuous recording of ECG). If all these are normal then no need to worry about arrhythmia or other heart diseases. Uncontrolled stress and anxiety are likely in your case. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need additional anxiolytic Chat Doctor.  Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
