<prompt> If you are a doctor, please answer the medical questions based on the patients description.in 2003 i was diagnised for cellular damage and high levels of protiens. my problem since then is i often get spreading sensation in my body and slightly get panicky.i have heart palpitations.i was on multiple vitamin treatment under a neurologist. my problem still persists. advice please.  <response>: Hi, This is Chat Doctor. Increased heart rate palpitations can have a lot of causes. It can be normal sinus tachycardia due to anxiety or stress, or it could be abnormal supra ventricular tachycardia. For the diagnosis, you need to do ECG at the time of palpitation tachycardia. If the duration of palpitations are short enough to reach a nearby hospital, we put a 24hr ECG monitoring Holder Monitor. You also need to do a 2D Echo thyroid function test to see for any associated abnormality if any. Thanks
