[|Human|] Hi my name is Stephen I have a question earler today I had a episode where I was driving and I noticed my heart starting to beat faster and faster then I started geting tingling down both arms and hands I went to a friends house and layed down within 20 min my heart rate was down and tingling was gone
[|AI|]  Hello! Thank you for asking on Chat Doctor! I carefully passed through your question and would explain that your symptoms could be related to anxiety. Anyway, I would recommend performing some tests to exclude possible cardiac arrhythmia: - a resting ECG and cardiac ultrasound in order to examine your cardiac function and structure- an ambulatory 24-48 hours ECG monitoring in order to examine your heart rhythm trends for a more prolonged time and exclude possible cardiac arrhythmia-some blood lab tests (complete blood count for anemia, thyroid hormone levels for possible thyroid dysfunction, blood electrolytes for possible imbalance). You should discuss with your doctor on the above tests. If all the above tests result normal, you should consider anxiety as the main cause of this clinical scenario. Hope you will find this answer helpful! Best wishes,
