HRV

HRV

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

HRV is a popular tool within psychophysiology as it can be an easy indicator to assess the relative contributions of the parasympathetic and sympathetic nerves to the control of basic cardiac rhythm. ECG, blood pressure, or arterial pulse recordings can be used to investigate this interplay between sympathetic and parasympathetic nervous systems. 

PowerLab and LabChart form a streamlined system to record and analyze heart rate variability (HRV). Run protocols for different stimuli and synchronize with either wireless or wired psychological response data.

Signals Supported

ECG
+

HRV analysis works best on an ECG recording but any recording that picks up a subjects pulse will work i.e: NIBP, Finger Pulse, Pule Oximetry.

Heart Rate
+

Options for both wireless and wired recording of heart rate as a reference to changes in cognitive and emotional states.

Features and Add-Ons

Additional acquisition and analysis features and add-ons to support your HRV studies:

Removing abnormal beats

HRV is typically performed on ECG recordings ranging in length from as short as 5mins to >24hours. The consecutive beat-t-beat intervals (R-R intervals) are extracted from the ECG. Since its the variations in time between normal heartbeats (N-N intervals) that is analyzed, it is essential that abnormal beats (such as ectopics and noise) are removed from the analysis. The HRV module in LabChart can automate this process for you.
