Background The current status of wearable cardiovascular defibrillators (WCD) use in Japan is unclear. Methods Using a nationwide claims database of Japan, we assessed characteristics of patients using WCD and factors influencing subsequent implantable cardioverter‐defibrillator (ICD) implantation. Results In 1049 cases, those with prior cardiopulmonary arrest (CPA) or ventricular arrhythmia, cardiomyopathy, or device‐related issues were more likely to require permanent ICDs, whereas females were less likely. Conclusions Prior CPA or fatal arrhythmia, underlying cardiomyopathy, or device‐related issues were associated with future permanent ICD implantation. These findings offer insights into the current status of WCD use in Japan.
