Reduction of inappropriate shock rate through signal filtering (smart-pass) in patients with implantable subcutaneous cardioverter-defibrillator: a systematic review and meta-analysis.

Subcutaneous implantable cardioverter-defibrillators (S-ICD) are effective in protecting patients against sudden death but expose them to a higher risk of inappropriate shock (IAS). We performed a systematic search of studies published between January 2010 and December 2019 assessing IAS due to cardiac oversensing by the selection process (PRISMA) and identified 17 eligible articles. Fifteen studies were observational, and two studies were retrospective.
