Autonomic function evaluated by ewing method in post-covid individuals in the municipality of gurup-to

Introduction: heart because it is an organ possessing its own ritmicity, needs to be regulated moment-to-moment to respond adequately to stimuli both endogenous and exogenous to the organism and such modulation is exerted by action of the Autonomous Nervous System (ANS) by two antagonistic pathways, the sympathetic trunk and the vagal parasympathetic, which together dictate the ritmicity and the natural variability of the frequency (HRV). From several clinical trials and varied methodologies proposed to study and understand the control of THE exercised over the heart, the five Ewing tests have been increasingly validated in the scientific environment and accepted for showing good results under epidemiological focus, making it possible to evaluate the degree of integrity of the connection between neural systems and the cardiac motor. Although still limited, evidence obtained from patients with covid-19 suggests that the virus has disproportionately affected preexisting cardiovascular diseases, as well as other comorbidity conditions, including diabetes and chronic respiratory diseases. Objective: to evaluate, through clinical trials of Ewing, the integrity of the ANS of 19 post-covid patients registered and seen at the Clinical School of Physiotherapy of the University of Gurupi (CEF-UnirG). The benefit will be extended to non-patients of CEF-UnirG, but recovered from covid-19. The project will run only when it receives final cep-unirg approval. Material and Method: 150 participants will be recruited composing the sample of post-covid 19 individuals, all with signatures in the TCLE. The basic instrumentation will be an electrocardiograph (ECG) and a blood pressure meter (BP) and protocols for the application of the five clinical trials of Ewing of a noninvasive nature, three related to the parasympathetic through measurements of the magnitudes of HRV and two of the sympathetic function involving blood pressure variation (APV). For this, ECG and BP data will be quantified, defined and expressed as intervals and/or indicators, which are compared with the normality standards proposed by Ewing et al. will determine the level of sensitivity and specificity, in addition to the degree of reproducibility, providing the methodological viability of Ewing tests in the evaluation of the integrity of THE in post-covid individuals 19.
