摘要：
Systems and methods for His bundle pacing using a stimulation device include applying an impulse to a His bundle of a patient heart using the stimulation device. The stimulation device then measures a response of the patient heart to application of the impulse that includes a response of a ventricle of the patient heart. The stimulation device calculates a ventricular delay as a time from application of the impulse to onset of the response of the ventricle and delivers, using a lead of the stimulation device, a backup impulse to the ventricle when at least the ventricular delay exceeds a delay value stored in a memory of the stimulation device. The stored delay may, for example, correspond to a previously determined value indicative of selective or other His bundle capture.
