摘要
A method and system for delivering a cardiac pacing therapy that includes a cardiac signal being sensed via electrodes of an atrial lead, and an occurrence of one of an intrinsic and a paced atrial depolarization event of a current cardiac cycle being determined in response to the sensed cardiac signal. A first pacing therapy is delivered during the current cardiac cycle in response to the determined occurrence of the depolarization event, and an amplitude of the cardiac signal within the current cardiac cycle subsequent to the delivered first pacing therapy is compared to a predetermined amplitude threshold. A second pacing therapy is delivered, via a left ventricular lead, within the same cardiac cycle and subsequent to the delivered first pacing therapy in response to the amplitude not being more negative than the predetermined amplitude threshold and is not delivered in response to the amplitude being more negative than the predetermined amplitude threshold.
