Eligibility

All

Inclusion criteria

Inclusion criteria: 1. Age >18 years 2. The subjects met the class I or class II indications for ICD therapy for primary prevention 3. Subjects can be screened by S-ICD ECG 4. The subjects are willing and able to sign informed consent and attend all relevant visits on time

Exclusion criteria

Exclusion criteria: 1. Pregnant 2. Subjects are participating in other clinical trials, which may affect this study 3. The researchers determined that the subjects were not suitable for S-ICD implantation, such as patients need or will need pacing therapy for bradycardia; Subjects with known ventricular tachycardia at a rate below 170 beats per minute or with refractory recurrent monomorphic ventricular tachycardia that could not be managed with medication or ablation therapy 4. Subjects implanted with a transvenous CRT-D or with history of pacemaker or ICD 5. Subjects with paced rhythms at baseline or post-implant of TV-ICD 6. Life expectancy <18 months
