Today, multiple ICD platforms are available, each with distinct strengths and limitations, making individualized device selection essential to optimize outcomes and minimize complications. The transvenous ICD remains the most established technology, offering reliable defibrillation, antitachycardia pacing (ATP), and pacing support, but is limited by lead-related complications and infection risk. The subcutaneous ICD avoids intravascular leads and is particularly attractive in younger patients and those at high risk of infection, although it lacks ATP and has shorter device longevity. The extravascular ICD is an emerging alternative designed to combine the advantages of both systems by providing ATP and shock therapy without intravascular leads, though implantation is more complex and long-term evidence remains limited. Given these differences, ICD selection should be guided by patient-specific clinical characteristics rather than a one-size-fits-all approach. Key determinants include pacing indication, prior lead failure, infection risk, body mass index, age, and arrhythmic substrate. The proposed clinical pathway offers a practical framework to support tailored ICD selection by integrating these variables into a structured decision-making process.

In Cohort 2 (n = 50), lead V8 facilitated intra-procedural assessment of LA activation. IAB was corrected in 20/23 (87%), accompanied by shortening of NDAT-P-V8 (from 120 ± 25 ms to 82 ± 17 ms, P < 0.001) and iso-V8 (from 51 ± 22 ms to 18 ± 17 ms, P < 0.001), consistent with earlier LA activation.</p><p><strong>Conclusion: </strong>NDAT-P-V8 closely reflects the invasively determined timing of the posterolateral LA activation and provides a simple non-invasive marker to assess the effect of BBP on LA activation. Lead V8 may therefore help to assess and optimize atrial activation with BBP.</p>","PeriodicalId":11981,"journal":{"name":"Europace","volume":" ","pages":""},"PeriodicalIF":10.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641076/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149059456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
