摘要：
Systems and methods of performing cardio resynchronization therapy (CRT) on a patient heart include the use of a stimulation system having at least one processor, at least one memory, a pulse generator, a stimulating electrode disposed in proximity to a His bundle of the patient heart, and a sensing electrode adapted to sense electrical activity of the left ventricle (LV) of the patient heart. CRT is provided by applying, using the pulse generator and through the stimulating electrode, a His bundle pacing (HBP) impulse having a first impulse energy. The sensing electrode is then used to measure an LV activation time in response to the HBP impulse. At least one setting of the pulse generator is modified based on the LV activation time such that a subsequent HBP impulse may be provided by the pulse generator via the stimulating electrode using a modified impulse energy.
