[|Human|] I have been having a fluttery feeling in my chest on and off today. I have not been weak, dizzy or faint. I have bot been running a fever or sweating. I have however had to stop to catch my breath a few times today after walking up stairs or reading out loud to my class. I have had a cough and cold for over a week now. What could it be?
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! Your symptoms could be related to a cardiac arrhythmia. But a lung infection can not be excluded either, considering the fact that you have been having fever. Coming to this point, I would recommend consulting with your attending physician for a careful physical exam and some tests: -a resting ECG- a chest X-ray study and pulmonary function tests- a cardiac ultrasound-complete blood count, PCR, ESR for infection-thyroid hormone levels - blood electrolytes. An ambulatory 24-48 hours ECG monitoring would help investigate for possible cardiac arrhythmia if suspicions are raised by the above-mentioned tests. Hope you will find this answer helpful! Kind regards,
