Comparison of ICD shock rates in Japanese and non‐Japanese patients in the PainFree SST study

Background The PainFree Smart Shock Technology (SST) study showed a low implantable cardioverter‐defibrillator (ICD) inappropriate shock rate. However, the majority of patients were from Western countries with patient characteristics different from those in Japan. ICD shock rates using the novel SST...

Description
Summary:Background The PainFree Smart Shock Technology (SST) study showed a low implantable cardioverter‐defibrillator (ICD) inappropriate shock rate. However, the majority of patients were from Western countries with patient characteristics different from those in Japan. ICD shock rates using the novel SST algorithms in Japanese patients are still unknown. Methods All 2,770 patients in the PainFree SST study (Japan [JPN]: N = 181, other geographies [OJPN]: N = 2,589) were included in this analysis. Results Japanese patients had higher average left ventricular ejection fraction (P
