If indications for implantable cardioverter\u2010defibrillator (ICD) therapy arise later, a subcutaneous ICD (S\u2010ICD) may represent an attractive option. However, S\u2010ICD implantation requires pre\u2010implant electrocardiographic screening, and pacing may impact implantation eligibility. Thus, the purpose of the present analysis was to evaluate S\u2010ICD screening eligibility in patients with right atrial (RA) and dual\u2010chamber (DR) LP during intrinsic rhythm, atrial pacing, and dual\u2010chamber pacing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p>Patients implanted with active\u2010fixation RA and dual\u2010chamber LP systems underwent S\u2010ICD screening using the automated screening tool. Electrocardiographic parameters were assessed during intrinsic rhythm, atrial pacing (AAI), and dual\u2010chamber pacing (DDD). Screening eligibility was assessed separately for each rhythm. Combined eligibility was defined as the presence of at least one acceptable vector in intrinsic and paced rhythms. Forty\u2010one patients were included (median age 67 years; 61% female). During intrinsic rhythm, at least one acceptable vector was present in 91.4% of patients. Screening eligibility remained high during atrial pacing (77.1%) but decreased substantially during dual\u2010chamber pacing (33.3%). Primary and secondary sensing vectors demonstrated the highest screening success across rhythm conditions, with positive rates of 60.0% and 62.3% for AAI, and 18.5% and 11.1% for DDD pacing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In patients with RA and DR LPs, S\u2010ICD screening eligibility is preserved in most cases during intrinsic rhythm and atrial pacing, but markedly reduced during DDD pacing.
