SPECIFIC PACING MODES FAVOURING INTRINSIC VENTRICULAR CONDUCTION
There is exhaustive evidence which show the detrimental effects of chronic right ventricular pacing. Any reduction in unnecessary right ventricular pacing also prolongs battery life and extends life of the pacemaker. Different modes have been proposed by the manufacturors to reduce the pacing percentage without compromising patient security during loss of atrioventricular intrinsic conduction. These modes are specifically designed for patients with sick sinus syndrome with preserved atrioventricular conduction or only paroxysmal loss of conduction. We will discuss the specificities of these modes as proposed by each manufacturor.
