Inclusion criteria
Inclusion criteria: Patients with diagnosis of heart failure with left ventricular ejection fraction (LVEF) = 50%, confirmed by an echocardiography examination conducted by a cardiologist; In both sexes; Older than 18 years; Hemodynamically stable: that in 48 h did not present malignant ventricular arrhythmias, ventricular extrasystoles complex, supraventricular or sinus tachycardia (greater than 120 beats per minute), 2nd or 3rd degree atrioventricular blocks and signs of low output; Have medical authorization to start rehabilitation.
Exclusion criteria
Exclusion criteria: Patients with cardiac arrhythmias that contraindicate physical exercises diagnosed by the cardiologist; Presence of diagnosed unstable angina; History of acute myocardial infarction for less than six months; History of cardiac surgery less than six months ago, fever within the last 48 hours with an increase in leukocytes and/or C-reactive protein seen on routine laboratory examination; Conditions that make it difficult or impossible to use virtual reality, such as visual impairment, cognitive dysfunction, psychiatric illness, presence of neurological diseases, history of photosensitive epilepsy due to the use of video games.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess satisfaction with exercise on a cycle ergometer associated with the use of virtual reality through the Physical Activity Enjoyment Scale (PACES), the higher the final score, the greater the satisfaction in performing the activity. | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluate the usability of the virtual reality system through the System Usability Scale (SUS) through the final score and classification according to Bangor et al (2009): 86 (best imaginable).;It is expected to observe an increase in exercise tolerance with the use of the virtual reality system. For the evaluation, the exercise time and the clinical parameters will be considered: systolic blood pressure, diastolic blood pressure, respiratory rate, peripheral oxygen saturation, heart rate and the subjective perception of effort. | — |
