    • Beta-Blockers reduce mortality in patients with congestive heart failure and a proposed mechanism has been changes of autonomic tone. Heart rate variability is a non-invasive tool to estimate cardiac autonomic tone. The aim was to study changes of heart rate variability in patients with congestive heart failure on placebo, on the beta1-selective antagonist metoprolol or 24 h after metoprolol withdrawal. Forty-five patients with congestive heart failure were studied with Holter recordings. Heart rate variability measurements were performed before, after 6-12 months of treatment with 150 mg metoprolol/placebo, or 24 h after discontinued metoprolol. After treatment, patients on beta-blockade had a significantly longer mean RR interval and changes of heart rate variability, suggesting elevated vagal tone. Patients monitored in the rebound phase of beta-blocker withdrawal had a significant vagal reduction to the level of the placebo group. There was also a nonsignificant trend towards increased sympathetic tone (LF/HF over 24 h), compared with the beta-blockade group. Heart rate variability indicates an elevated vagal tone during treatment with metoprolol but beta-blockade withdrawal shifts the autonomic balance towards lower vagal and higher sympathetic tone within 24 h. These results could imply a potential risk when abruptly discontinuing beta-blockade medication in these patients.
