Hello and thanks for the query
can not cause palpitations. It may be related to anxiety
if you are sensitive in nature. Otherwise to get to a diagnosis you need holter study or EKG at the time of palpitations. If it is heart related than it could be either AF or PSVT. Both the conditions are treatable with medications only like beta-blockers or calcium channel blockers.
If you get episode during holter study and your holter study is normal than it is surely be stress or anxiety related. Consult psychiatrist
