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

The novel AST predicted overall eligibility approximately similar to MST. Both tools predicted ineligibility in a few patients, who were actually eligible. There was a striking mismatch between both screening tools when eligibility of single vectors was predicted. Thus, the AST seems to be a valuable advance, due to its standardized and objective process, but it still lacks specificity.
