<bot>: Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms seem to be related to a cardiac arrhythmia. Anxiety or a muscle skeletal cause could not be excluded too. I recommend consulting with your GP for a careful physical examination and some tests : - resting ECG and a cardiac ultrasound-chest X-ray study - blood lab tests (complete blood count, thyroid hormone levels, blood electrolytes, PCR, sedimentation rate, kidney and liver function tests). An ambulatory 24-48 hour ECG monitoring is necessary to rule in/out possible cardiac arrhythmia. Meanwhile, I recommend you to closely monitor your blood pressure and heart rate and refer them to your attending physician. If all the above-mentioned tests result normal, the main cause of your symptoms would be just anxiety. Hope to have been helpful! Best wishes!
