Implantable loop recorder via subscapular approach in 2.7 kg neonate

Implantable loop records allow continuous heart rhythm monitoring with the ability to be stored and viewed remotely. The limited use in the pediatric population stems from the unknown indications of use and feasibility of implantation. We describe the case of a 2.7kg female with Long QT3. A loop recorder helped identify breakthrough tachycardia and helped her transition to the next stage of care. Placement was at the left subscapular region with no complications. Implantable loop recorder placement is achievable in a 2.7 kg patient at corrected gestational age 38 weeks for LQT3 syndrome monitoring and management.
