Do dual-chamber ICDs reduce inappropriate discharges compared to single-chamber ICDs in pediatric and young adult patients?
Dual-chamber ICDs do not reduce inappropriate shocks in young patients, suggesting the added complexity and cost of an atrial lead are unwarranted if used solely for rhythm discrimination.
In this cohort of young patients, DC ICDs did not provide added protection from IDs. Hence, the added complexity and cost of an atrial lead appear unwarranted if used solely for assistance with rhythm discrimination in young patients.
Lawrence et al. (Mon,) studied this question.
