Describes a new open-source toolbox for HRV analysis that includes standardized preprocessing and abnormal rhythm detection to improve accuracy over existing tools.
Existing HRV toolboxes do not include standardized preprocessing, signal quality indices (for noisy segment removal), and abnormal rhythm detection and are therefore likely to lead to significant errors in the presence of moderate to high noise or arrhythmias. We therefore describe the inclusion of validated tools to address these issues. We also make recommendations for default values and testing/reporting.
