[Cross-stimulation in endocardiac AV sequential demand DVI pacemaker associated with great dilatation of the right atrial appendage].
We report on a case of ventricular stimulation by an atrial electrode in endocardiac DVI sequential pacemaker implanted in a patient with cardiomegaly and great atrial appendage. The appropriately placement of the electrode was confirmed by open-heart surgery in the valve replacement. This rare malfunction could be exceptionally studied anatomically.
