Design outcomes

Primary

MeasureTime frame
Confidence intervals of the sensitivities and specificities of the different trained classifiers for the assignment day / night and rest / active when using the ECG data series for each patient.

Secondary

MeasureTime frame
1) reference range of the differences of the HRV parameters calculated at the same time interval from ECG and ICD data series for each patient, 2) confidence interval of the percentage agreement of the sympathetic and parasympathetic activity calculated for the same patient at the same time interval, 3) Descriptive statistics of the recorded faults.
