Impaired baroreflex control is associated with adverse prognosis in heart failure and post-MI patients, highlighting the potential prognostic value of autonomic tone assessment.
A range of techniques for the assessment of autonomic tone are described. Impaired baroreflex control of heart period, measured in terms of heart rate variability or baroreflex sensitivity, is independently associated with adverse prognosis in patients with heart failure and following acute myocardial infarction. These techniques have not yet entered routine clinical practice.
