Exercise training slows down heart rate and improves deceleration and acceleration capacity in patients with heart failure

Journal of Electrocardiology, 05/11/2012

Two groups of patients with chronic heart failure (CHF) treated with comparable pharmacological medications were enrolled into this study. One group entered a 24–week training program, whereas another group remained without it. After the completion of the study, there was a significant increase of mean RR interval, high– and low–frequency power of heart rate variability, and the magnitudes of deceleration capacity and acceleration capacity only in patients who underwent the cardiac rehabilitation program with controlled physical training.
