1. A method of detecting a fusion event following a delivery of a ventricular stimulation pulse, comprising:

  • detecting a far-field R-wave on an atrial channel, within a predefined time interval after verification of loss of capture on a ventricular channel;

    confirming the fusion event if the far-field R-wave is detected on the atrial channel following the ventricular stimulation pulse; and

    confirming loss of capture if no far-field R-wave is detected on the atrial channel.
