I think the narrowing of the refractory period would be the main culprit. When you make the refractory period shorter, it gives more time for an errant impulse to trigger a response. I saw this firsthand when I learned how to control my flutter with potassium. Potassium does the opposite and widens the refractory period, and if you widen it enough it can stop the repeating circle of flutter by causing the impulses to arrive too late to trigger another beat. The same general principle would apply to afib: wider refractory period, less arrhythmia (within limits, obviously).

So it appears that in Norpace and Propafenone, they lengthen the refractory period of the atrium. So I still can't figure out why those two drugs have worsened the atrial tachycardia.
