Key Points

Highlight the analytical dangers of deriving heart rate and variability measures from unverified blood volume pulse data and outline best practices for signal artifact management.
Assesses methodological factors involved in monitoring peripheral blood flow, heart rate, and heart rate variability using raw blood volume pulse recordings.
Identifies prevalent sources of signal contamination and formulates practical recommendations for artifact identification and data cleaning.
Demonstrates that failing to inspect raw blood volume pulse signals directly risks invalidating secondary metrics such as pulse amplitude, heart rate, and respiratory sinus arrhythmia.
Outlines practical precautions and signal treatment protocols to systematically detect and mitigate artifact-driven contamination.

Implication

May warrant routine raw BVP inspection before HR/HRV use in practice or trials; leaves open standardized artifact protocols for biofeedback research.

Abstract

Blood volume pulse is a popular method for monitoring the relative changes in peripheral blood flow, heart rate, and heart rate variability. This article stresses the danger of blindly interpreting measures like heart rate, which are derived from blood volume pulse, without close inspection of the raw blood volume pulse signal. The authors identify common sources of signal contamination and recommend practical precautions and treatment of artifacts.
