The information gathered in this study will be compared for differences in clinical background between the primary and secondary assessments. The main studies were the correlation between the presence or absence of transition to implantable defibrillation device and the clinical background, VT/VF events under observation and background factors (especially left ventricular function, ventricular arrhythmia, which is considered to be strongly associated with prognosis, renal function) and survival prognosis by comparing what kind of patient background the WCD is likely to work or whether it is transferred to implantable defibrillation device. Kaplan-Meier curves will be used for prognosis, and multivariate analysis is used for strength of association. This will examine the appropriate adaptation criteria for WCD use in Japanese. Cases of discontinuation/dropout and missing values shall be the period until those values are valid.
