Narrative:

About 1 hour into flight from sfo to ZZZ, I was advised of an ill passenger in the cabin. After conferring with a doctor, a paramedic, and an emergency room nurse that were attending to her, it was determined that her life was now in danger. I made the decision to declare a medical emergency and return to sfo. This, unfortunately, meant that we would be landing 7500 pounds over the maximum structural landing weight of the aircraft. We proceeded to sfo and landed on runway 28L. The landing was very smooth and without incident. The aircraft also checked out by maintenance to be fine. We were met by medical staff from the airport, and passenger was attended to and removed from the aircraft to be taken to the hospital.
