[|Human|] Hi Doctor, I am a female and over the last couple of weeks I have noticed that my heart seems to be beating fast and when this happens I have noticed I seem to have diaorrhea. Before this, it was just a racing pulse and my throat felt like it was closing up. Tiredness when I go to bed and wake up I feel fine. but today during the day my heart rate seems to be racing. No pains in my chest only twice heartburns and that was a week ago. I am 46 years old five foot 4ins Thank you
[|AI|]  Hi, Increased heart rate and 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 and 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 and thyroid function test to see for any associated abnormality. Hope I have answered your query. Let me know if I can assist you further.
