The physiology of the escape rhythm (ER) and its response to pharmacological modulation under varying autonomic conditions were studied in 48 patients undergoing radiofrequency ablation of the atrioventricular junction (AVJ) for refractory atrial fibrillation. The QRS morphology and cycle length (CL...
