Abstract

A method, and devices for timing the delivery of non-excitatory signals for modifying myocardial contractility of the heart includes applying electrodes to a plurality of cardiac sites (RA, RV, LV), using a first electrode (2A, 4A) at a first cardiac site (RV, RA) to detect a first electrical depolarization event within a beat cycle, using a second electrode (6A) at a second cardiac site (LV) to detect a second electrical depolarization event within a beat cycle, and applying a non-excitatory signal to the heart near at least the second cardiac site (LV) through at least one of the electrodes (6A) in response to detecting the second electrical depolarization event within an alert window period. The applying of the non-excitatory signal is delayed from the time of detecting of the second electrical depolarization event. The devices may also be adapted for pacing the heart, and/or for delivering de-defibrillation signals to the heart.
