Should I continue my beta blocker? It.

Hello doctor, I'm 32 years, male having no comorbodities. I got Covid on 17th November, 2020 and was in home quarantine and came out of it on 1st of December. Apart from other Covid related medicines, I was also provided Prolomet XL 12.5 at 11am each day from 17.11.2020. God's grace I was all good apart that I faced palpitations a few time post recovery. I did my ECG and 2D Echo on last week of December which suggests absolutely normal report. On 2nd week of January, I did my Holter which suggests average hear beat of 76, minimum of 51 and max of 122, 7% of total in tachycardia and 5% of total in bradycardia and occasional sinus Arrhythmia which my local doctor suggested as all good. I do not face any palpitation any more for last two months, my pulse rate stays around 75-80, BP around 120/70, Lipid profile parameters in range. Just I'm oversized by 15 kilo & I'm working on it. Should I continue my beta blocker because my doctor still wants me to have it.
