The death of a patient who allegedly spent two hours waiting for emergency department admission in Tasmania is under investigation.

The state Greens say the woman, who died at the Royal Hobart Hospital on Tuesday, was "ramped" - the process of keep patients in an ambulance before admission to a hospital's emergency department.
