Narrative:

Lax-lhr. Crew: I (captain), 2 first officer's, and 1 flight attendant. During the flight the captain indicated that he was 'uncomfortable.' he appeared to be 'anxious' and apprehensive about the crossing to lhr. I attributed this to his unfamiliarity with lax-lhr route. Prior to the approach into lhr, the captain said he was not feeling well and that I should fly and land the aircraft and he would manage the radio communication (very normal procedure). Soon he was feeling worse and decided it would be best if the (augment) #2 first officer sat in the captain's seat. The captain retained command and assisted with traffic watch as the 'observer.' a message was sent to the lhr operations explaining our situation and to please advise all controling agencies. We were given expeditious handling and landed uneventfully on runway 27R at london. Paramedics met the aircraft and the captain, who was ambulatory, went to a local hospital. We later heard that he may have had a minor stroke. Appropriate company contact and procedures were accomplished by operations and flight crew post landing. Supplemental information from acn 468981: captain indicated to both crew members that he was not feeling well and was confused and disoriented. A discussion about alternatives and possibilities in case of incapacitation. A decision by all crew members was made. The captain moved to the jump seat, the flying first officer continued in his position for the landing, and me, as the augmented first officer, sat on the left (captain's) seat for the landing. London operations was advised via ACARS of the situation. The captain was still in command except for the manipulation of the controls. Clear and SOP resources were used to continue the landing and taxi to the gate. No safety was jeopardized and the flight ended uneventfully. Captain was met by ambulance team and taken to an area hospital where later was diagnosed with a mild stroke.
