Introduction: Cerebrovascular diseases can influence the autonomic nervous system. Studies have shown that heart rate variability is related to the severity of stroke, with some predictive values of mortality and suggest that there is an autonomic imbalance, especially in sympathetic activity, with the possibility of increasing heart rate variability through rehabilitation programs. In the respiratory sinus arrhythmia maneuver, it is possible to assess parasympathetic modulation on autonomic heart rate control. The assessment of Heart Rate Variability in Stroke is still little used. Objective: To evaluate factors and the effectiveness of a rehabilitation program that interfere in the Heart Rate Variability of patients after a stroke. Method: For systematic review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes checklist was adopted and for the development of the search strategy, we used the Patient-Intervention-Comparison-Outcomes-Study strategy. A search was conducted in virtual databases, in English, Portuguese and Spanish. In the experimental study, individuals with up to 72h after ischemic stroke were evaluated, conscious, by means of a cardiofrequency meter, who performed a maneuver of respiratory sinus arrhythmia. Results: We obtained 88 studies from the databases, four of which completed the process of inclusion, exclusion and eligibility. In the experimental study, 42 patients were divided into 2 groups. Conclusion: The possibility of modulating Heart Rate Variability in patients after ischemic stroke during protocols of mobilizations or physical activities observed in the reviewed studies and with the experimental study was demonstrated, we observed that the maneuver of respiratory sinus arrhythmia influences the variability of the respiratory sinus. heart rate in both groups.
