It is a prospective, controlled, single-center, observational, non-randomized study. The study is planned to include at least 500 patients 18 years old and older (300 patients in the training sample and 200 patients in the test sample.
The study will include all patients requiring exclusion of the diagnosis of acute pulmonary embolism. Patients will be examined according to clinical guidelines to confirm the diagnosis of pulmonary embolism (laboratory, clinical and instrumental).
During the course of the study, the authors of the work do not interfere with the scope of the examination, which is caried out on patients in accordance with clinical guidelines.
All patients included in the study will undergo electrocardiogramm (ECG) in standart lead I for 1 minute, followed by spectral analysis of the obtained data, which will be stored at the Remote monitoring center of Sechenov University without being linked to the personal data of patients. A spectral analysis of the electrocardiogram will be performed using a continuous wavelet transformation. The result of this study will be the identification of ECG parameters that will correlate with pulmonary embolism.
A clinical condition requiring exclusion of acute pulmonary embolism;
The presence of written informed consent of the patient to participate in the study;
Age from 18 years old and older
Refusal to undergo examination or the inability to reliably verify or exclude the diagnosis of pulmonary embolism;
Poor ECG quality, preventing the necessary analysis of a single-channel ECG;
Incomplete examination, preventing a reliable determination of the presence or absence of pulmonary embolism;
Refusal to further participate in the study.
