Heart Rate Variability (HRV) is determined by analyzing the time series of beat-to-beat intervals from an electrocardiogram (ECG).

HRV analysis has become one of the most popular methods of ANS evaluation. It is based on the observation that even at rest the duration of RR intervals is not constant but continually fluctuates around the mean value.

ECG, blood pressure, or arterial pulse recordings can be used to investigate the interplay between sympathetic and parasympathetic nervous systems.

PowerLab and LabChart combine to form a powerful, customizable system to record and analyze heart rate variability (HRV) in animals for your ANS research.
