[|Human|] Hi doctor, I am 54 yrs and a week ago I stared taking norethisterone tabs for long periods.  I am worried since the then my heart have been beating very fast, i dont know whether theres a connection.  also I have not been sleeping very well recently bacause I get very hot at night.
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I passed carefully through your question and would explain that your symptoms are related to Noethistersone with Chat Doctor.  An electrolyte imbalance could also mimic this clinical scenario. Coming to this point, I would recommend performing a resting ECG, a complete blood count and blood electrolytes. If these tests result normal, there is nothing to worry about. Your situation will improve spontaneously in the next weeks. Hope you will find this answer helpful! Kind regards,
