Abstract
Official abstract text for this publication.
In a pacing mode where the left ventricle is paced upon expiration of an escape interval that is reset by a right ventricular sense, there is the risk that the left ventricular pace may be delivered in the so-called vulnerable period that occurs after a depolarization and trigger an arrhythmia. To reduce this risk, a left ventricular protective period (LVPP) may be provided. Methods and devices for implementing an LVPP in the context of multi-site left ventricular pacing are described.
First claim
Opening claim text (preview).
What is claimed is: 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…
