A neural link to explain the "muscle hypothesis" of exercise intolerance in chronic heart failure.

abstract：BACKGROUND:Atrial fibrillation (AF) ablation is superior to pharmacologic therapy in achieving maintenance of normal sinus rhythm in selected patient populations. However, the procedure is resource intensive, and repeat ablations are sometimes required. We examined the predictors and trends of repeat ablation using a l...
