Comparative Study Clinical Trial Controlled Clinical Trial
Long-term evaluation of autonomic tone in patients below 50 years of age with unexplained cerebral infarction: relation to atrial vulnerability.
Preliminary studies have described, in young patients with unexplained cerebral infarction, electrophysiological abnormalities similar to those observed in paroxysmal atrial fibrillation. Moreover, in young adults with 'normal' hearts, increased susceptibility to paroxysmal atrial fibrillation with autonomic abnormalities as assessed by heart rate variability analysis have been reported. ⋯ The long-term autonomic tone parameters of young patients presenting with a history of unexplained cerebral infarction are similar to those of healthy control subjects and are not correlated with atrial vulnerability parameters or atrial fibrillation inducibility.
