Abstract

The benefits reported after pacemaker implantation ranging from improvement in symptoms and quality of life, even an increase of hemodynamic parameters such as ejection fraction. Ergospirometric testing in elderly patients before and after pacemaker implantation showed improved cardiac output and cardiopulmonary capacity one week after implantation, concluding that elderly patients with bradycardia took advantage of the pacemaker implant. The device implantation and the stigma of becoming a cardiac patient, acts as a limiting factor in physical activities. Physical inactivity has a direct relationship with the greatest risk for developing cardiovascular disease. Because it is an easy and accessible, aerobic exercise is the most suitable and acceptable, besides being the type of exercise that promote prevention and improvement of cardiovascular diseases, involving large muscle masses which move cyclically. Primary Objective: evaluate the effect of exercise on quality of life and functional capacity in pacemaker patients without ventricular dysfunction. Secondary Objective: compare the effects of supervised exercise training with unsupervised in pacemaker patients without ventricular dysfunction. Variable outcomes: quality of life score, maximal oxygen consumption, physical activity level. Methods: A prospective, consecutive, randomized control group. We will study patients with pacemakers, selected by clinical evaluation in Cardiac Pacing Unit of InCor and submitted the following evaluations: physical examination, questionnaire on the level of physical activity, questionnaire of quality of life and cardiopulmonary exercise test. Patients will be randomized as follows: 1. Supervised training 2. Unsupervised 3. Control. After four months of follow-up patients will undergo further evaluation. The hypothesis is that the pacemaker patients will have additional benefits with exercise training. (AU)
