摘要
A method and system for atrial capture detection based on far-field R-wave (FFRW) sensing is provided. After establishing that stable FFRW sensing exists, presence of atrial capture can be detected by atrial sensing of the FFRW in a predetermined FFRW detection window following an atrial pace. Threshold values for the atrial pace can be determined by varying an atrial test variable and observing whether a FFRW occurs in the FFRW detection window. In another embodiment, threshold values for the atrial pace can be determined by applying a search pace before the regular atrial pace, varying an atrial test variable for the search pace, and monitoring the movement of the FFRW between the FFRW detection window and a predetermined search detection window located before the FFRW detection window.
