Cardiac Support

The ER adjusts to the new department head who questions Rorish's decisions. An ambulance arrives with its paramedics knocked out by their patient, who attacks Jesse. Later, Jesse has a heart attack. As the doctors try to save him, other patients include a man hit by a train, the daughter of a controlling Beverly Hills mother, and the wife of a veteran who is struggling with addiction. Meanwhile, Mario leaves the hospital to find the train victim's son with intellectual disabilities, against Hudson's orders.
