Narrative:

I was notified by the senior flight attendant that a crew member in the back was having a heart attack. While trying to call company medics; operation; deviating around WX; we declared a medical emergency and started dumping fuel. Flight engineer advised me that #2R dump valve did not open; I asked him to do what needs to be done to dump to maximum landing weight. Flight engineer then advised me again that after resetting circuit breaker; the valve opened and now we are dumping normally. Landed safely; and the crew member was taken to the hospital. The fuel dump procedure was noted in logbook with no discrepancy. Arrived to ZZZ with 35000 pounds of fuel with landing weight of 367000 pounds. Received a call from flight manager to inform me of a possible discrepancy with fuel. Arrival fuel to be 63000 pounds instead of 35000 pounds; an overweight landing that we were not aware of. At that time we did not have any reason to suspect an uplift discrepancy or a possible overweight landing. Callback conversation with reporter revealed the following information: the reporter does not understand why the flight manager is questioning their landing fuel. As far as he knows they landed with 35000 pounds of fuel; just under maximum landing weight. The dump valve worked normally after the circuit breaker was reset; and there was no reason to enter a discrepancy in the logbook.
