Yes. Heart beating donor means the patient has been declared as Brain-stem Dead, and his /her organs can be retrieved when heart is still beating with the assistive devices. Beating heart keeps the blood supply intact to organs and there is no damaging affect of low blood supply to organs.
In case of donation after cardiac death, heart has stopped beating and there is no blood supply to organs. Because of that, donation after cardiac death has to be done immediately, as without blood supply, the organs will not be viable for use after certain period of time.
