1. A system comprising:
an electrocardiogram (ECG) sensor or a photoplethysmograph (PPG);
a galvanic skin response (GSR) sensor or an acoustic sensor;
one or more processors; and
a memory comprising instructions adapted to configure the one or more processors to classify one or more sleep-disordered breathing (SDB) events of a patient, wherein by the instructions, the one or more processors are configured to:
control an analysis of (a) at least one of (i) sympathetic activity data of the patient from a signal generated by the GSR sensor or (ii) acoustic data representing heart sound of the patient from a signal generated by the acoustic sensor and (b) at least one of (i) ECG data of the patient from a signal generated by the ECG sensor or (ii) pulse oximetry data of the patient from a signal generated by the PPG; and
classify the one or more SDB events into apneas and hypopneas, and/or into open and closed airway events, based on the analysis.
