Left ventricular dysfunction after long-term right ventricular apical pacing in the young

Abstract: In the presence of impaired LV function with long-term RV apical pacing, alternative sites of ventricular pacing that simulate normal biventricular electrical activation should be explored to preserve function in pediatric patients in need of long-term pacing.

However, with conventional RV apex pacing, the impulse is conducted from the apex to the base of the heart and from the right to the left ventricles, and therefore the time for impulse conduction in the ventricles is significantly prolonged.1,2) This procedure is reported to cause ventricular dyssynchrony, 3,4) resulting in an increased risk for occurrence of heart failure 5-7) or atrial fibrillation. 7,8) Recently, selective site pacing (SSP), where alternate sites for ventricular pacing are used, has come into use to improve ventricular dyssynchrony.…”

“…Since the 1980s, evidence of the harmful effects of RV apical pacing related to the long-term effects on cardiac structure and function has been reported [23][24][25][26] . High levels of stimulation in the ventricular channel may lead to undesirable left ventricular remodeling, with consequent increased morbidity and mortality, particularly in patients presenting systolic dysfunction 27 .…”

“…Esse fenômeno tem sido correlacionado à deterioração da função ventricular esquerda e ao desenvolvimento de insuficiência cardíaca grave. Esse tipo de problema também tem sido reportado em crianças submetidas à estimulação ventricular direita crônica, por marca-passo de câmara única ou AV 31,34 .…”
