Direct comparison of the novel automated screening tool (AST) versus the manual screening tool (MST) in patients with already implanted subcutaneous ICD

摘要

Background: The subcutaneous implantable cardioverter-defibrillator (S-ICD) has evolved as a valuable alternative to the transvenous ICD, especially in young patients. Unfortunately, some of these patients are ineligible for S-ICD implantation due to specific electrocardiographic features. So far, these patients were identified by mandatory pre-implantation screening using the manual screening tool (MST), which lacks objective value. Therefore, a novel automated screening tool (AST) has been introduced recently for objective screening, which has not been evaluated yet.
