Can a heart beat in heaven acording to Catholics?

I have a question regarding the "properties" of heaven. As far as I understand heaven is place outside of space and time. I imagine it like this since it is the only way i can make sense of eternity. However if we believe in resurrection, then it we will have our bodies which are material. If we are alive then our hears will beat. If there is a beat then time must exist since a beat represents a change between 2 instants. How does Catholic doctrine reconcile this (possible) paradox?
