Effect of defibrillation energy on pacing threshold.
After an episode of electrical defibrillation, periods of increased pacing threshold may cause lack of pacing in pacemaker patients. This effect is independent of the energy applied during defibrillation, although the data suggest that the most rapid return to prefibrillation pacing thresholds occurs after minimal energy countershocks.
