Abstract
Methods for timing pacing pulses in an implantable single chamber pacemaker create a simulated, or virtual chamber in order to apply dual chamber-type algorithms and modes. For example, a virtual atrium may be constructed based on information provided by the ventricle, that is, the timing of actual intrinsic ventricular events, and the timing of paced ventricular events, both of which may be sensed as ventricular depolarization by electrodes of the implanted system.
Claims12
A method for timing pacing pulses in a single chamber implantable cardiac pacemaker, the method comprising applying one or more dual chamber pacing algorithms by creating a virtual chamber.
An implantable single chamber cardiac pacemaker comprising a pulse generator having a microprocessor pre-programmed to time pacing pulses delivered by the pulse generator, according to one or more dual chamber algorithms, by creating a virtual chamber.
