“…Although the prognostic value of HRV reduction has not been demonstrated in Chagas' disease, it is known that in several cardiac and systemic diseases, reduced HRV is a strong and independent prognostic marker, with good prediction of adverse events 12 - 14 . In heart failure from other causes, there is an association between reduced indices with adverse events, such as decompensation, hospital readmissions, ventricular dysfunction progression and mortality 32 - 34 .…”

Background:Heart rate variability (HRV) is a marker of autonomic dysfunction severity. The effects of physical training on HRV indexes in Chagas heart disease (CHD) are not well established.Objective:To evaluate the changes in HRV indexes in response to physical training in CHD.Methods:Patients with CHD and left ventricular (LV) dysfunction, physically inactive, were randomized either to the intervention (IG, N = 18) or control group (CG, N = 19). The IG participated in a 12-week exercise program consisting of 3 sessions/week.Results:Mean age was 49.5 ± 8 years, 59% males, mean LVEF was 36.3 ± 7.8%. Baseline HRV indexes were similar between groups. From baseline to follow-up, total power (TP): 1653 (IQ 625 - 3418) to 2794 (1617 - 4452) ms, p = 0.02) and very low frequency power: 586 (290 - 1565) to 815 (610 - 1425) ms, p = 0.047) increased in the IG, but not in the CG. The delta (post - pre) HRV indexes were similar: SDNN 11.5 ± 30.0 vs. 3.7 ± 25.1 ms. p = 0.10; rMSSD 2 (6 - 17) vs. 1 (21 - 9) ms. p = 0.43; TP 943 (731 - 3130) vs. 1780 (921 - 2743) Hz. p = 0.46; low frequency power (LFP) 1.0 (150 - 197) vs. 60 (111 - 146) Hz. p = 0.85; except for high frequency power, which tended to increase in the IG: 42 (133 - 92) vs. 79 (61 - 328) Hz. p = 0.08).Conclusion:In the studied population, the variation of HRV indexes was similar between the active and inactive groups. Clinical improvement with physical activity seems to be independent from autonomic dysfunction markers in CHD.

“…The utility of HRV analysis in the context of chronic disease is well established. HRV analysis demonstrates abnormalities in the ANS activity and is correlated with increased risk of death in individuals with cardiovascular disease, diabetes, chronic kidney disease, and many other conditions [13][14][15][16][17][18].…”

In a healthy person, the sinoatrial node generates rhythmic, regular signals that lead to a contraction of the heart muscle. As early as the 18 th century, it was noted that in animals the pulse rate changes with respiration, and in the mid-19 th century, respiratory variability of heart rate was confirmed in humans [1]. Differences in the distance between successive RR waveforms, as recorded on electrocardiography, are a sign of cardiovascular well-being and are referred to as heart rate variability (HRV) (Figure 1).The primary regulator of heart rate variability is the autonomic nervous system. Thanks to autonomic regulation the heart rate increases or decreases (Figure 2).Analysis of HRV thus provides information about the interplay between the sympathetic and parasympathetic parts of the autonomic nervous system (ANS) and the potential disruption of this delicate balance, influenced by various factors [2].Historical milestones in the study of the cardiovascular system and its variation under the influence of respiration were presented by Billman [1]. The first researchers to highlight the clinical aspects of HRV (in the foetus) were Hon and Lee [3]. In the following years, numerous researchers explored this issue and developed tools to assess the ANS, as described in detail by the aforementioned Billman [1]. HRV analysis became clinically important in the late 1980s when heart rate variability was found to be
