Multi-day heart rate variability monitoring via Holter electrocardiogram for depression detection: Clinical validation and translational challenges

Key Points

• This research aims to validate the use of heart rate variability monitoring via Holter electrocardiogram for detecting depression.
• Conducted a randomized trial with clinical participants
• Utilized Holter electrocardiogram for multi-day heart rate variability assessment
• Analyzed data for potential biomarkers of depression
• Heart rate variability was significantly associated with depression symptoms (p<0.05 for correlation)
• The biomarker approach showed a predictive accuracy of over 80% for depression identification
• Clinical validation supports the feasibility of Holter monitoring in detecting depressive states
