<bot>: Hello! Welcome on Chat Doctor! I carefully read your question and would explain that his symptoms seem to be related to a cardiac arrhythmia. Anxiety could also be related to this clinical scenario. I would recommend consulting with his attending physician and performing some tests: - a resting ECG- a chest X-ray study-lab blood tests (complete blood count, cardiac enzymes, thyroid hormone levels, fasting glucose, blood electrolytes, kidney and liver function tests)An ambulatory 24-48 hours ECG monitoring would be necessary to examine his heart rhythm trends during the day. Hope you will find this answer helpful! Best wishes,
