    Selective site right ventricular pacing has been suggested as an approach to reduce the incidence of ventricular dysfunction and hopefully influence the morbidity resulting from traditional right ventricular apical pacing. Pacing from the right ventricular apex allows a stable ventricular rate, and together with atrial pacing and sensing, helps maintain atrioventricular synchrony but does not allow physiological activation of the left ventricle. Traditional atrial pacing sites like the right atrial appendage may encourage atrial tachyarrhythmias, whereas lead placement in right atrial septal sites may reduce the frequency of symptomatic atrial tachyarrhythmia episodes, especially when combined with prevention algorithms. Researchers attempting to pace the heart from these selective sites have been hindered by the lack of uniform definitions of where these sites actually lie and the inadequacy of tools to consistently reach these locations and verify correct placement. This lack of definition consensus may have contributed to the apparent conflict of data, particularly in the right ventricle. There is an urgent need for a standardization of terms and identifying measures for selective pacing sites.
