Since major depressive disorder (MDD) is a heterogeneous disorder, researchers study its diverse phenotypes. Heritability ranges from 26%...

Slow-paced contraction (SPC) provides an alternative and unproven method for determining the resonance frequency (RF) in one or two...

Behavioral neuroscience discoveries have proceeded at a rapid pace. This series highlights cutting-edge findings and explains their...

Randomized controlled trials have demonstrated the efficacy of HRV biofeedback for diverse clinical disorders like depression, diabetes,...

Measurement context and client characteristics are crucial to interpreting HRV time- and frequency-domain measurements. In this post, we...

HRV Time-Domain Measurements for Smart People describes these measurements, caveats, and practical applications.

During slow-paced breathing between 4.6 to 6.5 bpm, you can examine your client's raw heart rate (HR) and respiration waveforms,...

Slow-paced contraction to increase heart rate variability

The low-frequency (LF) band (0.04-0.15 Hz) is affected by breathing from ~3-9 bpm (Task Force, 1996). The baroreflex system’s resonance...

The electrocardiograph (ECG) and photoplethysmograph (PPG) are two methods of detecting heart rate (HR) and heart rate variability (HRV)....

Respiratory sinus arrhythmia (RSA) is the speeding and slowing of the heart across each breathing cycle. RSA is the primary and entirely...

Heart rate (HR) is important because a high rate can reduce heart rate variability (HRV), the changes in the time intervals between...
