Narrative:

While in cruise flight, I noticed my first officer leaning way over to the left as if reaching down to pick up something on the floor. Thinking he lost something, I asked what he was looking for. After asking twice with no response, I realized that he had lost consciousness. I checked that the aircraft, autoplt, and controls were not being affected, and then pushed on my first officer to get him sitting up straight. I looked to lock in his shoulder harness, but he did not have them on. I called his name a couple of times and he regained consciousness. At this point I began to ascertain his physical and mental condition. I asked him a few questions and I could see that he was fully alert and not in physical distress. I considered diverting to another airport, but felt for several reasons that it would be best for all concerned to continue to our destination. The remainder of the flight was uneventful. I estimate that my first officer was unconscious for less than 1 min.
