Hi, Anxiety can cause an increase in heart rate and palpitations which is a normal phenomenon. The heart rate becomes normal as soon as the stimulus goes away. The exact diagnosis of the palpitation depends on the time of the ECG if the ECG is taken at the time of palpitations then a proper diagnosis can be made. But as the palpitations are short-lived, we generally advise for a 24hr continuous ECG monitoring of the heart which is called Holder monitoring. You don't need any medication for now but further management will depend on the Holder report. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
