Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that it is necessary performing some tests to differentiate between different possible causes that may mimic this clinical scenario: cardiac arrhythmia, a lung disorder, thyroid dysfunction, electrolyte imbalance or anxiety. For this reason, I recommend consulting with his doctor and performing the tests below: - a cardiac ultrasound and a resting ECG- an ambulatory 24-48 hours ECG monitoring in order to examine his heart rhythm trends for a prolonged time and exclude possible cardiac arrhythmia- a chest X-ray study and pulmonary function tests-complete blood count for anemia-thyroid hormone levels for thyroid dysfunction- blood electrolytes for electrolyte imbalance. If all the above-mentioned tests result normal, you should consider anxiety as the main cause of his complaints. Hope you will find this answer helpful! Wishing good health,
