WebPatients with AV node ablation become chronotropically incompetent. This condition may be corrected by rate-adaptive pacing. While rate-responsive pacing can help these patients to adapt during exercise, it can also elicit an excessive increase in heart rate with possible deleterious effects. Device programming should be meticulous.
