Prevention of Crosstalk in Dual Chamber Pacemakers
Atrioventricular crosstalk in dual chamber pacemakers is when the atrial stimulus is sensed by the ventricular sensing amplifier, leading to inhibition of ventricular output . With atrioventricular (AV) crosstalk, for example, a 5 V stimulus from the atrial channel might be sensed as a small (0.3 V) artefact by the QRS detector (Fig. 1).
