Abstract: Cardiac pacing methods for an implantable single chamber pacing system, establish an offset rate for pacing at a predetermined decrement from either a baseline rate (i.e. dictated by a rate response sensor), or an intrinsic rate. Pacing maintains the offset rate until x of y successive events are paced events, at which time the offset rate is switched to the baseline rate for pacing over a predetermined period of time. Following the period, if an intrinsic event is not immediately detected, within the interval of the offset rate, the rate is switched back to baseline for pacing over an increased period of time. Some methods establish a preference rate, between the offset and baseline rates, wherein an additional criterion, for switching from the offset rate to the baseline rate, is established with respect to the preference rate.

Abstract translation: 用于可植入单室起搏系统的心脏起搏方法，以基线速率（即由速率响应传感器指定）或内在速率以预定减量建立起搏偏移率。 起搏维持偏移率，直到y个连续事件的x为起搏事件，此时偏移速率被切换到预定时间段内的起搏基准速率。 在该期间之后，如果不立即检测到固有事件，则在偏移率的间隔内，速率将在增加的时间段内切换回基线。 一些方法在偏移和基线速率之间建立偏好率，其中针对偏好率建立用于从偏移率转换到基线速率的附加标准。
