[CRITERIA FOR SHORT AND LONG-TERM PROGNOSIS IN HOSPITALIZED PATIENTS BASED ON THE ECG SIGNAL CHARACTERISTICS AT ADMISSION. RATIONALE AND STUDY DESIGN].

: The article presents the rationale and design of a prospective observational study devoted to the evaluation of criteria for short-term and long-term prognosis in hospitalized patients based on the characteristics of the ECG signal at admission to hospital. The purpose of this study is validity and predictive accuracy of predictive scores SCS, Tan et al., characteristics of standard ECG and ECG dispersion mapping to detect the short-term (30 days) prognosis of mortality and annual mortality in patients at admission to hospital. The objectives of the study are to study the calibration and prognostic ability of the above predictive scores and criteria, as well as a comparison of their predictive accuracy.
