Abstract
BACKGROUND
The effect of physical training (PT) on QTc dispersion and ventricular tachycardia (VT) remains unclear in patients with nonischemic heart failure.
METHODS AND RESULTS
Eight patients with nonischemic heart failure performed PT using a bicycle ergometer and their exercise tolerance increased (4.9+/-1.8 to 7.0+/-2.5 METs, p<0.05) and QTc dispersion decreased (71+/-22 to 48+/-24 ms, p<0.05). However, PT did not change the frequency of VT.
CONCLUSION
Physical training could improve QTc dispersion in patients with nonischemic heart failure, possibly by improving the autonomic nerve system.
