New Citations | BIOPAC in HRV Analysis Research


ECG and HRVBIOPAC provides researchers with a complete range of tools to gather data on heart rate variability (HRV). The following studies demonstrate just some of the ways in which HRV research benefits from the implementation of BIOPAC hardware and software solutions.


Post-traumatic stress disorder (PTSD) has been associated with dysfunction of the autonomic nervous system. Reduced HRV is a key indicator of abnormalities in the parasympathetic nervous system, a contributing factor in autonomic disfunction. Researchers used a BIOPAC ECG amplifier and data acquisition system to gather data for their analysis of HRV.

Aiken, Mascha Van’t Wout-Frank, and Noah S. Philip.

The Connection between Autonomic Activity and Adverse Childhood Experiences

Adverse childhood experiences (ACEs) can impact autonomic activity well into adulthood. To investigate this connection, psychophysiology markers, including HRV, were gathered via a BIOPAC ECG Smart Amplifier and MP160, then calculated using AcqKnowledge data analysis software.

Predicting Cardiovascular Disease 

Autonomic regulation of blood pressure and cardiac rhythm progressively declines with age. Resting heart rate and HRV data were gathered using a BIOPAC ECG amplifier and data acquisition and analysis system, as well as a noninvasive blood pressure module to predict cardiovascular disease and better understand how to maintain overall cardiac health among an aging population.
