A man who died while waiting to see a doctor in a Philadelphia emergency room appeared to have expired within 11 minutes of signing in, a police official said. Police said a security videotape from the Aria Health-Frankford Campus hospital clearly showed Joaquin Rivera, 63, going into distress at 10:56 p.m. Rivera struggles to breathe, brings his hand to his chest, then falls still in his seat. It was only at 11:45 p.m., nearly 50 minutes after Rivera stopped moving, that hospital personnel noticed he appeared to be dead, a witness in the waiting room told police.
