Autonomic Testing


The Autonomic Testing software application derives time and frequency domain based signals related to Heart Rate Variability (HRV) and the Baroreflex Sensitivity (BRS). The HRV signals are derived from the ECG signal and are based on an interval of 5 minutes.  Subsequently, every heart beat the HRV signals are updated. The BRS signal is calculated using a cross correlation method. More detail on the calculation method can be found in the article describing its validation: Time-domain cross-correlation baroreflex sensitivity: performance on the EUROBAVAR data set
