摘要：

We applied the respiratory sinus arrhythmia (RSA) quantification algorithm to 24-hour ECG recordings of Chagas disease (ChD) patients with (G1, n = 148) and without left ventricular dysfunction (LVD) (G2, n = 33), and in control subjects (G0, n = 28). Both ChD groups displayed a reduced RSA index; G1 = 299 (144-812); G2 = 335 (162-667), p = 0.011, which was correlated with vagal indexes of heart rate variability analysis. RSA index is a marker of vagal modulation in ChD patients. (C) 2014 Elsevier B.V. All rights reserved.
