Randomized Controlled TrialNear elimination of ventricular pacing in SafeR mode compared to DDD modes: a randomized study of 422 patients.
SafeR performance versus DDD/automatic mode conversion (DDD/AMC) and DDD with a 250-ms atrioventricular (AV) delay (DDD/LD) modes was assessed toward ventricular pacing (Vp) reduction. ⋯ In this selected patient population, SafeR markedly suppressed unnecessary Vp compared with DDD modes.

Case ReportsFetal and neonatal presentation of long QT syndrome.
This report describes a fetus presenting with intrauterine tachycardia and hydrops fetalis. Soon after birth the neonate was noted to be in torsades de pointes that responded dramatically to medical management. ⋯ The prognosis is poor when LQTS presents in utero or during the first week of life. However, our infant did well with medical management and has remained free of arrhythmias at follow-up.
