Abstract:
1. An implantable cardiac device, comprising: sensing circuitry for receiving cardiac signals from the right and left ventricles; pacing circuitry for delivering pacing pulses; a controller for controlling the operation of the pacing circuitry in accordance with a selected pacing mode; circuitry for determining a timing relationship between intrinsic ventricular depolarizations of the left and the right ventricles; and, circuitry for selecting between a right ventricular, left ventricular, or biventricular pacing mode by which to provide pacing pulses based on the timing relationship between intrinsic ventricular depolarizations of the left and the right ventricle, wherein the selected pacing mode determines the manner in which paces are delivered over multiple cardiac cycles.
