Other: chronic heart failure | Other: chronic heart failure To conduct the exercise to the inspiratory muscles was used for IMT Threshold ® device (Threshold Inspiratory Muscle Trainer, HealthScan Products Inc., Cedar Grove, New Jersey) is one of the most used for training of inspiratory muscles in patients with several pathologies such as ICC.Threshold ® has been engaged in the patient's mouth by a mouthpiece, with the nose occluded by a nose clip. The exercise time was 3 minutes. During this period, participants were encouraged to only breathe through the mouth and maintain a respiratory rate between 12 and 16ipm. The exercise would be stopped if HR increased more than 20% and / or SpO2 < 88%. |
