Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that a thyroid dysfunction may be the cause of your symptoms. Nevertheless, a cardiac disorder can not be excluded. I recommend consulting with your GP for a careful physical examination and some tests: - resting ECG and cardiac ultrasound to examine your cardiac function and structure-chest X-ray study -blood lab tests (complete blood count, thyroid hormone levels, blood electrolytes, fasting glucose, vitamin B12 levels, kidney and liver function tests, fasting glucose, PCR, sedimentation rate). An ambulatory 24-48 hours ECG monitoring is necessary to examine your heart rate trends during the day. You should discuss with your attending physician on the above issues. Hope to have been helpful! Greetings!
