Left ventricular pacing in neonates and infants with isolated congenital complete or advanced atrioventricular block: short- and medium-term outcome

Abstract

At short- and medium-term follow-up, LV pacing results in satisfactory LV electromechanical function and synchrony in neonates and infants with CCAVB.

Echocardiographic assessment of ventricular contraction and synchrony in children with isolated complete atrioventricular block and epicardial pacing: Implications of interventricular mechanical delay

“…TA B L E 2 Comparison between the short IVMD group and the long IVMD group has become a preferred ventricular pacing site in children, including neonates and infants. 13 There is growing evidence that epicardial LV pacing provides better LV contraction and mechanical synchrony in children with isolated atrioventricular block. 3,14 Improved clinical outcome could be expected under our current treatment strategy to avoid suturing a ventricular lead at the RV outflow tract.…”

Electroanatomic mapping‐guided localization of alternative right ventricular septal pacing sites in children

“…QRS duration was evaluated in standard 12‐lead ECG. QRS duration was measured manually from standard ECG (recorded at a paper speed of 25 mm/s) . Echocardiographic evaluation was performed routinely prior to pacemaker implantation, and postoperatively after 1 month and 1 year.…”

What endocardial right ventricular pacing site shows better contractility and synchrony in children and adolescents?

“…QRS and QT duration were measured manually from standard ECG recorded at a paper speed of 25 mm/s; QT duration was measured by two independent readers and the QT interval was calculated by the tangent method. If calculations differed between readers, the average value was used . The QTc interval was calculated according to Bazett's formula.…”
