Screening for Pulmonary Embolism Using Single-channel Electrocardiogram Data Using Machine Learning Models

Inclusion Criteria

Inclusion Criteria: 1. A clinical condition requiring exclusion of acute pulmonary embolism; 2. The presence of written informed consent of the patient to participate in the study; 3. Age from 18 years old and older Non-inclusion criteria: 1. Refusal to undergo examination or the inability to reliably verify or exclude the diagnosis of pulmonary embolism; 2. Treatment, in particular anticoagulant therapy, before recording a single-lead ECG; 3. Conditions in which recording an ECG in lead I is not possible (congenital anomalies of the upper limbs, traumatic amputation of the upper limbs, tremor, etc.); 4. Refusal to sign written informed consent to participate in the study. Exclusion Criteria: 1. Poor ECG quality, preventing the necessary analysis of a single-channel ECG; 2. Incomplete examination, preventing a reliable determination of the presence or absence of pulmonary embolism; 3. Refusal to further participate in the study.
