Paradoxical induction of cross-talk in a dual chamber pacemaker by increasing the ventricular output.
Cross-talk was induced in a unipolar DDD pacemaker by increasing the output of the ventricular channel. Oversensing by the ventricular channel was probably due to the detection of a relatively large summation signal consisting of the afterpotential and the superimposed activity from the atrial stimulus.
