Outcomes of single- or dual-chamber implantable cardioverter defibrillator systems in Japanese patients

Conclusions Dual-chamber ICDs were four-fold more common in Japanese patients without a pacing indication. No benefit over single-chamber ICD was observed. Newly developed atrial pacing-dependency seemed to be limited and could have been overestimated due to higher pacing rate settings in dual-chamber patients.
