Bisoprolol 2. 5 mg for APCs. Medicine?

Hello Doctors, During last month regular health check up we incidentally found out 7.5% load of APCs (supraventricular) in holter. Was advised to take Concur cor 2.5 for 2 months. I am taking the medication from last one month and feeling fine. Had no bothering symptoms before and have no symptoms now. I am thinking of stopping the medication now? Can I stop? If yes, how should I taper it as it is said that I can't stop beta blocker all of a sudden. Also, will there be any side effect of taking this medication for a month. Asking because many suggested that this was not needed and I am worried that taking medication without needed might affect otherwise. Please suggest! Note:- I also did echo last month and was normal. Any follow up tests needed after leaving this medicine?
