Abstract

Objective: Several studies documented the relevance of autonomic activity in the pathophysiology of heart failure. In our study we evaluated the adjustment of this activity under different stimuli, by means of heart rate variability (HRV), and correlated these findings with long-term mortality and sustained VT occurrence. Patients and method: Fifty-three patients (mean age 54±9 years) with heart failure were submitted to time and frequency domain HRV analysis. This latter analysis was performed at rest, during paced breathing and during passive tilt. Results: Lower standard deviation of RR intervals (76.76±24 versus 107.70±43, p=0.02), mean of the 5-min standard deviations of RR intervals (35.14±15 versus 62.39, p
