Default Inward rectifying potassium channels

well i have read that inward rectifying potassium channels allows an inward potassium current. book says in experiments it can cause influx of potassium, but also found out that it only allows inward potassium movement. so if this is the case how opening of these channels help in re-polarization of heart muscle?
It should cause further depolarization? plz help me in clearing this comfusion.

actually these channels allow movement of Potassium OUT of the cell only...as far as the movement in to the cel is considered, it is only found EXPERIMENTALLY.....

qissa yu hy k asal mein tou yeh potassium efflux he krwate hain but kisi ek experemint mein inhon ne influx bhi krwa diya hy jis ki wajah se inn ka naam Inward Rectifying Channel rakha gya,just to differentiate it from other Potassium channels
