ATRIAL CAPTURE MANAGEMENT DURING ATRIAL AND VENTRICULAR PACING
摘要
In an atrial pacing system (100), the A-PACE pulse energy, defined by the pulse width and pulse amplitude, sufficient to reliably capture the atrium (12) without being wasteful of battery energy is periodically determined in accordance with atrial capture management (ACM) algorithms. The ACM algorithms allow a slow intrinsic atrial heart rate that is suppressed by delivered A-PACE pulses resulting in A-CAPTURE and that occurs when delivered test A-PACE pulses result in ALOC to be detected. ALOC is declared if an A-EVENT of the slow intrinsic atrial heart rate is detected either during an ACM test window timed from the last delivered test A-PACE pulse or during delivery of a sequence of test A-PACE pulses delivered within or defining the ACM test window correlated to the slow intrinsic atrial heart rate.
