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.
我们将呼吸性窦性心律不齐（RSA）量化算法应用于患有（G1组，n = 148）和未患有左心室功能障碍（LVD）（G2组，n = 33）的恰加斯病（ChD）患者的24小时心电图记录，并应用于对照组（G0组，n = 28）。两个ChD组的RSA指数均降低；G1组为299（144 - 812）；G2组为335（162 - 667），p = 0.011，这与心率变异性分析的迷走神经指数相关。RSA指数是ChD患者迷走神经调节的一个指标。
