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.
