ANSLAB has efficient procedures for the editing and analysis of continuous

• electrocardiography (ECG)
• impedance cardiography
• pulse plethysmography
• blood pressure
• skin temperature.

It includes powerful spectral and other variability analyses relevant for, e.g.,

• heart rate variability / respiratory sinus arrhythmia
• baroreflex sensitivty
• respiratory variability.

Advanced options include chaos measures (e.g. detrended fluctuation analysis), crossspectral analysis, and time-frequency analysis such as complex demodulation.
