No p-wave occurs so the pacer fires the atrial pacing wire causing a pacer spike on the EKG. The pacer then waits the programmed amount of time to see a QRS. If no QRS occurs the ventricular pacing wire is activated and a paced QRS occurs. At any point in the process the heart can kick in with it own beat and inhibit the pacer. It sounds like in this person the pacer is firing for the SA node and his own rythmn responds and carries through with the rest of the beat.
