above description
Population
Teenagers and adults, age range: 12-87
Application
site
hospitals
Accuracy
The accuracy of this function is reflected by the balance performance of
sensitivity and specificity.
Others
This function does not generate any alarm when using, so it should be
operated by professional or trained personal.
3. Algorithm description
This section describes the algorithm, formulas and judgment conditions for interpretation
items related to functions of ECG automated measurement and automated interpretation.
The 12-lead sync ECG waveform passes through the filter (AC, EMG, DFT (if has, and
open)) into the module of automated measurement and automated interpretation.
The module of automated measurement and automated interpretation mainly includes
process of find the cardiac impulse location, find the beginning/end for each wave, amplitude
calculation, parameters calculation, and interpretations judgment based on known parameters.
