Introduction. Spinal cord injury is considered serious disabling neurological syndrome, occurs mainly in young adults. The heart rate variability has been used as a noninvasive means to assess the neural control of heart analyzing fluctuations. Objective. To assess heart rate variability in patients with spinal cord injury underwent an incremental test of upper limbs. Method. Four male subjects with a diagnosis of spinal cord injury performed an incremental test to maximal effort on a cycle ergometer of upper extremities. All records of heartbeats were made with the use of a heart rate monitors (Polar® S810 Heart Rate Monitor). These recorded beats were directed to a computer through an interface IR emission of infrared signals, so that they could carry out analysis of heart rate variability by using the Polar Precision Performance software. Results. The values of heart rate variability are greater in individuals with spinal cord injury highest (T1) compared with individuals with spinal cord injury lowest (T3, T6, T10). Conclusion. The variability of heart rate was higher in individuals with SCI at T1 when compared with individuals with lower TRM (T3, T6, T10).
