Inclusion criteria
Inclusion criteria: Wearable Heart Failure Monitor (WHFM) and Cardiovascular Event Smartwatch Verification: 1. Medium- and high-risk patients who were screened by heart failure and SCD risk early warning models and admitted to Beijing Hospital, including 34 patients with acute heart failure. 2. Control group: 10 patients with non-heart failure who visited Beijing Hospital were included. without any indication for a diagnosis of heart failure; Blood tests and echocardiography are performed as clinically indicated. Wearable Electrocardiogram Monitor (WCM) and Cardiovascular Event Smartwatch Validation: 1. Disease group: 34 patients with premature ventricular contractions/ventricular tachycardia were included in the intermediate- and high-risk patients who were screened by heart failure and SCD risk early warning models and visited Beijing Hospital. Diagnostic criteria: short burst ventricular tachycardia or premature ventricular holter >= 2000 premature beats/day. 2. Control group: 10 patients with non-ventricular premature contractions/ventricular tachycardia who visited Beijing Hospital were included. Diagnosis of premature ventricular contractions/ventricular tachycardia; Holter examination is performed 1-3 days according to its clinical indications.
