Dynamic Metrics of Heart Rate Variability
نویسندگان
چکیده
Metrics of heart rate variability (HRV) are widely used in medical diagnostics, physiological research, and biofeedback training (TaskForce, 1996; Wheat & Larkin, 2010). HRV metrics are typically based on non-invasive measurements of cardiac function using electrocardiography (ECG) or photoplethysmography (PPG). A specific point is identified in each cardiac cycle, and the inter-beat interval (IBI) between those points in adjacent ECG heartbeats or PPG pulsebeats is measured.

Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...

Based on psychophysiological research, coherent heart-brain interaction can change afferent cardiac signal pattern sent to the brain. Accordingly, the present study aimed at facilitating the emotion-cognition interaction through HeartMath Institute self-regulated emotional techniques to investigate the efficacy of heart-brain coherence on reading anxiety reduction that significantly enhances at...
