NCT07099417

Brief Summary

It is a prospective, controlled, single-center, observational, non-randomized study. The study is planned to include at least 1000 patients over 18 years old in the training sample and 200 patients over 18 years old in the test sample (the total number of patients is at least 1200 people). All patients will undergo an echocardiography examination with a comprehensive analysis of the function of the valves and other structures of the heart according to current recommendations by two independent experts. Registration of electrocardiogram will be performed immediately after echocardiography using a single lead ECG monitor (in I standard lead) for 1 minutes. The obtained data will be stored in 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 transform. The result of this study will be the identification of ECG parameters that will correlate with valvular heart disease.
