This study is a prospective, open-label, randomized controlled trial designed to evaluate a new artificial intelligence (AI) tool for heart monitoring. Researchers will use an AI-enabled electrocardiography (ECG) system to screen patients before they undergo surgery. The main goal is to determine if this AI system can accurately detect pulmonary hypertension and related heart diseases in the preoperative setting. The study is being conducted at Taipei Veterans General Hospital.
Age between 18 and 80 years.
Patients scheduled for non-cardiac surgery under general anesthesia.
Patients who have a scheduled standard preoperative electrocardiogram (ECG).
Patients capable of understanding the study and willing to provide medical records for research purposes, and who have signed the informed consent form.
Patients scheduled for emergency surgery.
Patients who explicitly refuse to participate or withdraw consent.
Patients with specific comorbidities that interfere with ECG interpretation or data collection (e.g., implanted pacemakers).
