What is Single Versus Dual Chamber Pacing in the Young: : Noninvasive Comparative Evaluation of Cardiac Function about?

__The advantages of atrial synchrony over asynchronous ventricular pacing remain unclear in the young, chronically right ventricular (RV) ‐ paced patient. This is in contrast to the older patient with inherent diastolic dysfunction who has been shown to benefit from atrial synchrony with dual chamber (DDD,R/VDD), over single chamber rate response (VVI,R) ventricular pacing. The goal of this study was to noninvasively assess cardiac function in a group of young, RV‐paced patients before and after establishment of atrial synchrony. Echocardiographic data were retrospectively analyzed from 10 patients with congenital or acquired complete AV block, who were VVI,R paced for 10.2 ± 2 years (mean age at study 19.2 ± 8.9 years), and were subsequently converted to DDD,R/VDD pacing (mean age at study 20.7 ± 9.5 years). Paired t‐test analysis of left ventricular (LV) systolic and diastolic function during VVI,R versus DDD,R/VDD pacing did not result in any short‐term difference in LV short axis fractional area of change or FAC (53%± 7.5% vs 56.8%± 8.7%) or mitral maximal velocity (E) normalized to mitral flow velocity time integral (VTI) (5.2/s ± 1.5 vs 4.4/s ± 1.5). A decrease in mitral flow
