Disease diagnostics by discretized ECG signal
The discovery of Dr. M.Sc. Prof. V.M.Uspensky:
Early diagnosis of numerous diseases by ECG is possible, and it is enough to use only signs of increments of amplitudes Rn+1 - Rn, intervals Tn+1 - Tn and angles αn+1 - αn.
Screenfax diagnostic system (2nd generation)
- more than 10 years of operation
- more than 20 thousand precedents (cardiogram + diagnosis) of more than 50 diseases
- more than 20 of them have selected reference samples
ECG information analysis technology according to V.M.Uspensky
- calculation of amplitudes, intervals and angles from a cardiogram of 600 cardiocycles length
- calculation of codogram - 599-character string in 6-letter alphabet
- calculation of 63 = 216 attributes - frequencies of trigrams formation of reference samples:
- sick patients (a separate sample for each disease)
- search for diagnostic standards - sets of trigrams that occur together in patients with a given disease
- training of the classification algorithm statistical evaluation of diagnostic accuracy
- by control samples or sliding control
- application of the classification algorithm for diagnosis
