Abstract:
1. A cardiac pacing device, comprising: pulse generation circuitry for generating pacing pulses; sensing circuitry for sensing cardiac electrical activity; a controller for detecting cardiac events that define pacing timing intervals and for controlling the delivery of pacing pulses in accordance with a programmed mode; a switch matrix operable by the controller for connecting the pulse generation circuitry and sensing circuitry to selected electrodes in order to form selected sensing and pacing channels; wherein the controller is programmed to: sense cardiac activity through right ventricular and left ventricular sensing channels; schedule delivery of paces through left ventricular pacing channels to at least two left ventricular sites designated LV initiate a first left ventricular protective period for site LV initiate a second left ventricular protective period for site LV
