NEW YORK (CNN) -- A 49-year-old woman collapsed and died on the floor of a waiting room at a Brooklyn psychiatric hospital and lay there for more than an hour as employees ignored her, according to the New York Civil Liberties Union, which on Tuesday released surveillance camera video of the incident.

Esmin Green was involuntarily admitted to the psychiatric emergency department of Kings County Hospital Center on June 18 for what the hospital describes as "agitation and psychosis."

Upon her admission, Green waited nearly 24 hours for treatment, said the civil liberties union, which was among the groups filing suit against the facility last year seeking improved conditions for patients.

The surveillance camera video shows the woman rolling off a waiting room chair, landing face-down on the floor and convulsing. Her collapse came at 5:32 a.m. June 19, the NYCLU said, and she stopped moving at 6:07 a.m. During that time, the organization said, workers at the hospital ignored her.

At 6:35 a.m., the tape shows a hospital employee approaching and nudging Green with her foot, the group said. Help was summoned three minutes later.

In addition, the organization said, hospital staff falsified Green's records to cover up the time she had lain there without assistance.

"Contrary to what was recorded from four different angles by the hospital's video cameras, the patient's medical records say that at 6 a.m., she got up and went to the bathroom, and at 6:20 a.m. she was 'sitting quietly in waiting room' -- more than 10 minutes since she last moved and 48 minutes after she fell to the floor."

The New York City Health and Hospitals Corporation, which oversees the hospital, released a statement Tuesday saying it was "shocked and distressed by this situation. It is clear that some of our employees failed to act based on our compassionate standards of care."
