Biofeedback treatment increases heart rate variability in patients with known coronary artery diseas
Biofeedback is shown to improve Heart Rate Variablity in patients with coronary artery disease a good thing, being as how diminished HRV is associated with increased morbidity and mortality in these patients.
In a randomized controlled trial at The California School of Professional Psychology at Alliant International University in San Diego, researchers investigated whether biofeedback could improve heart rate variablity (HRV) in patients with coronary artery disease (CAD). Diminished HRV is associated with increases in cardiac morbidity and mortality.
Sixty-three patients with CAD were randomly assigned to either conventional therapy or to six biofeedback sessions, consisting of abdominal breath training, heart and respiratory physiologic feedback, and daily breathing practice.
The study concludes that biofeedback increases HRV in patients with CAD and therefore should be considered as an integral tool for improving cardiac morbidity and mortality rates.
