Abstract
Closed-loop stimulation (CLS; BIOTRONIK SE & Co. KG, Berlin, Germany) is a rate-responsive algorithm that analyzes intracardiac impedance trends using a standard lead placed in the right ventricle. It is unknown whether CLS could perform adequately with His bundle (HB) lead placement, as contractility dynamics may be attenuated in this region compared to the right ventricle apex.We performed hand-grip, mental, and bicycle exercise tests in a patient with brady atrial fibrillation and permanent HB pacing. The CLS algorithm responded with an appropriate heart rate to mental and physical tests. Learning objective: A combination of permanent His bundle and closed-loop stimulation-driven pacing may be a valid and physiological option for atrial fibrillation patients with chronotropic incompetence.Entities:
