This video shows the ANS Analysis add-on module for long-term measurement. It makes it possible to carry out measurements without time limits. In addition to the display of the heart rate variability, the parasympathetic activity is visualized as a blue line in real time. With the special marker and memo function, individual markers can be created and set before and during the measurement. The effect of therapeutic interventions on the autonomic nervous system can thus be illustrated for more detailed therapy monitoring during the measurement.
