Webb21 juni 2011 · Only the 123 I-MIBG washout rate was a multivariate predictor of an AF recurrence (hazard ratio: 1.6, 95% confidence interval: 1.004–1.125, P = 0.037). Conclusions: Excessive sympathetic nervous activation may be one of the mechanisms of AF recurrences. WebbMyocardial MIBG washout correlated inversely with SDNN (r =-0.390; P &lt; 0.05) and with VLF (r =-0.459; P &lt; 0.01) component of HRV but not with heart rate at rest (r = 0.207, P = ns).
