Abstract:
A method for timing the delivery of a non-excitatory signal to a heart within a cardiac beat cycle, the method comprising the steps of:applying electrodes to a plurality of cardiac sites;sensing electrical activity in at least a first site of said plurality of cardiac sites through at least a first electrode of said electrodes for detecting a first electrical depolarization event within said beat cycle;sensing electrical activity in at least a second site of said plurality of sites through at least a second electrode of said electrodes for detecting at least a second electrical depolarization event within said beat cycle; andapplying said non-excitatory signal to at least one of said cardiac sites through at least one of said electrodes in response to detecting said second electrical depolarization event within an alert window period, said alert window period starts at a first delay from the time of detection of said first electrical depolarization event and has a first duration, said applying is delayed from the time of detecting of said at least second electrical depolarization event.
