Hi I've Had An Cathater Abilation 2 Days Ago Because

Hi I've had an cathater Abilation 2 days ago because I was diagnosed with Wolf Parkinson's White . The procedure was successful however when I got up to go to the bathroom I realized I had like two consecutive beats instead of one and they put me on a portable heart monitor and it came again once I started walking .now it's the third day it happened again while I was taking my shower. Is this common and is it dangerous? Please help im worried
