ABSTRACT:
A method and apparatus for pacing the atrium to reduce the incidence of dangerous arrhythmias. Electrodes are located at least two locations within the atrium, preferably in the triangle of Koch and/or an area of prolonged effective refractory period elsewhere within the atrium. Additional or alternative electrode locations may also be employed. The apparatus defines a variable interval following atrial depolarizations, based on the detected rate of the depolarizations. In response to a sensed depolarization at one of the locations, outside the variable interval, pacing pulses are delivered at least to the electrodes located at the other locations. Demand atrial pacing using some or all electrodes is also provided.
