Abstract

A method for setting the parameters of an alert time window in an excitable tissue control device operative under a plurality of different cardiac conditions of a heart of a patient. The method includes providing said excitable tissue control device with a set of data including a plurality of sets of alert time window parameters. Each set of window parameters is uniquely associated with a different set of values of a plurality of cardiac condition defining parameters identifying one of the different cardiac conditions. Each set of window parameters includes at least a set of timing parameters usable for obtaining a beginning time point and an ending time point of the alert window. The sets of window parameters are obtained by processing data collected within a data collection session from a plurality of cardiac beats of the same patient under the different cardiac conditions. The methods updates for each current beat cycle the values of a plurality of cardiac condition defining variables corresponding to said cardiac condition defining parameters, automatically selects a current set of alert time window parameters based on the current values of the cardiac condition defining variab…
