Introduction: Cerebral Palsy (CP) is a disease that causes neuromuscular disorders, cardiovascular diseases (CVDs), in addition to disorders autonomic and homeostatic. Objective: To measure the cardiac autonomic modulation of children and young people with CP. Methods: Quantitative cross-sectional and observational study. The electrocardiogram R-R intervals (IRR) were collected from 5 volunteers in wheelchairs, aged 6 to 18 years with CP through the cardiofrequencimeter Polar model V800â. Results: The average age is 12.4 years, both genders, body mass of 35.1 kg, height of 1.39 m and body mass index of 16.8 kg/m2 equivalent to malnutrition. The data show cardiac autonomic modulation in the time domain, the standard deviation variables of all normal RR intervals 60.0 ms, square root of the mean of the sum of squares of the differences between normal IRR 60.3 ms, percentage of adjacent IRR greater than 50 ms 16.1% and in the frequency domain, low heart rate (un) 55.7, high heart rate (un) 44.2, the ratio of discharge to low heart rate 2,3. Conclusion: Children and adolescents with CP have a low heart rate variability, with a greater probability of developing CVDs, due to sedentary lifestyle.
