Is autonomic function associated with left ventricular systolic function in Chagas heart disease patients undergoing treatment for heart failure?
Introduction The association between cardiac autonomic and left ventricular (LV) dysfunction in Chagas disease (ChD) is controversial. Methods A standardized protocol that includes the Valsalva maneuver, a respiratory sinus arrhythmia (RSA) test, and an echocardiographic examination was used. Spearm...
