Inclusion criteria
Inclusion criteria: 1. Age >= 18 years, with independent cognitive ability, able to cooperate with the investigation; both male and female participants are included. 2. Able to undergo non-invasive physiological signal monitoring, including but not limited to ECG, body surface blood pressure, temperature, and other examinations. 3. Patients diagnosed with clinical heart failure or excluded from clinical heart failure based on initial clinical evaluation. (Note: This inclusion criterion refers to the initial clinical evaluation based on suspected heart failure symptoms. The final diagnosis of heart failure or non-heart failure will be determined through further expert evaluation, which will be conducted blinded to the initial classification.) 4. Patients must consent to participate in the study and sign the informed consent form.
Exclusion criteria
Exclusion criteria: 1. Patients with electrocardiogram findings suggestive of ventricular fibrillation or ventricular tachycardia. 2. Electrical cardioversion or defibrillation performed within the preceding 7 days. 3. Ongoing blood purification therapy, extracorporeal membrane oxygenation (ECMO), or intra-aortic balloon pump (IABP) support. 4. Massive pericardial effusion or cardiac tamponade. 5. Bilateral upper-limb injuries precluding non-invasive blood pressure measurement. 6. Severe stenosis of brachial subclavian or brachial artery. 7. Inability to maintain a supine or semi-recumbent position required for signal acquisition. 8. Determination after enrolment that the participant did not meet inclusion criteria. 9. Occurrence of a serious adverse event that made continuation unsafe. 10. Patients or their legal guardians requesting withdrawal from the study. 11. Patients deemed unsuitable to continue the study by the investigator.
