[|Human|] I have been having heart palpitations shortness of breath, weakness and tremors. I have had these symptoms separately before, but never together. I have hypothyroidism and high blood pressure. I have not had an unusual change in anxiety, caffeine, herbal supplements or activities. I am 38, 6 and 290# (28% body fat). Should I be concerned?
[|AI|]  Hi, This is Chat Doctor. 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(SVT).SVT is common especially in hypothyroid patients. 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 to see for any associated abnormality if any. Thanks
