WebApr 10, 2024 · The AV response to overdrive atrial pacing at rest may provide a simple means of identifying chronotropic competence in CRT patients. For patients with CI, who often require rate-adaptive atrial pacing, rate-adaptive AV algorithms should be adjusted individually. 1 Introduction WebChronotropic incompetence is defined as failure to reach 80% of the expected maximum heart rate (age-adjusted). To determine this it is necessary to perform an exercise stress test, during which it is fundamentally important that the patient performs maximally.
