Abstract
A cardiac stimulation device, a His Bundle lead, and an associated method for detecting a conduction signal from the His Bundle. Upon this detection, the stimulation device delivers ventricular stimulation to the right and/or left ventricles at an interval following the atrial depolarization. A sensing window is initiated following the sensing of the atrial depolarization. During the sensing windows, the His Bundle signal received through the His Bundle lead is sampled and a moving average is calculated to determine a signal peak. Detection of the His Bundle signal peak triggers ventricular stimulation, which may be delivered to the right ventricle, the left ventricle, or both ventricles.
