A Monmouth County grand jury indicted 39-year-old Lorie Hentges of Brick on a charge of first-degree murder.
She accused of killing 72-year-old Alvin Flamenbaum of Toms River in April 2007.
Monmouth County Prosecutor Luis Valentin says the murder took place in the cardio-thoracic intensive care unit of Jersey Shore University Medical Center in Neptune.
Flamenbaum had a long history of heart disease and had undergone numerous surgeries.
Hentges surrendered to authorities today, and was freed on $250,000 bail.
Her lawyer says she "is guilty of nothing other than holding the hand of a dying man."
