In our latest episode of The AJP-Heart and Circ Podcast, Associate Editor Dr. Jason Carter (Baylor University) interviews authors Dr. Michael Joyner (Mayo Clinic), Dr. Nathaniel Jenkins (University of Wisconsin-Madison), Dr. Austin Robinson (Indiana University), Dr. Nisha Charkoudian (Environmental Physiologist in the Boston Area), and Dr. Manda Keller-Ross (University of Minnesota) about their recent Guidelines in Cardiovascular Physiology article about rigor and reproducibility of heart rate variability (HRV) within human cardiovascular research. Carter et al. take an evidence-based approach to propose more consistent and rigorous measurement and interpretation of HRV within human cardiovascular research and application. Listen to this engaging conversation about the utility of HRV as a cardiovascular risk stratification tool, but also the challenges of interpreting and contextualizing HRV assessments using wearable technology.
