Ds 5700

The CR group participated in a supervised exercise training program at the hospital’s gym 2 - 3 times 1 week for 1 year. Exercise intensity was chosen at the estimated 50% of peak VO₂ according to heart rate and Borg’s scale 11-13 during exercise as referenced by previous reports [10 (link), 11 (link)]. Each session lasted about 1 h, beginning with a warm-up exercise for 10 min, followed by 30 min of cycling or walking at the indicated exercise intensity and 20 min of cooling down and stretching. Blood pressure and heart rate were measured at rest and at the end of exercise, and an electrocardiogram (Central Monitor (DS-5700), Fukuda Denshi Co., Ltd, Tokyo, Japan) and Borg’s scale were recorded during exercise. All patients were routinely screened before each exercise session, such as by symptoms, heart rate and rhythm, electrocardiogram, blood pressure and medication regimen. The following conditions had to be managed during exercise: angina, dysrhythmia, hypotension, hypertension, dyspnea, decreased exercise tolerance and cardiac or respiratory arrest. Emergency equipment was immediately available in the exercise area, and the emergency cart, resuscitation equipment and medications were checked regularly. Our CR staff is well trained at administering basic life support and advanced cardiac life support.
