Additionally, there are clearly problems related to ILRs, including oversensing, missed arrhythmias and device-related complications such as infection or malfunctions. [...]problems have been better dealt with, in children, their use should probably be limited to a small subset of patients who have exhausted all other, less invasive, means of assessment.
