Key result
Patients with paroxysmal atrial fibrillation exhibited a heightened susceptibility to vasovagal responses, with 25% having a positive tilt test compared to 0% in normal controls.
Why the study?
Do patients with paroxysmal atrial fibrillation have abnormal cardiovascular autonomic function or vasovagal reactions compared to normal controls?
Population

Comparison
Cardiovascular autonomic function tests… vs Normal control subjects.

May support autonomic evaluation in paroxysmal AF; hypothesis-generating and requires prospective validation before clinical adoption.
Case-Control (n=47)
Do patients with paroxysmal atrial fibrillation have abnormal cardiovascular autonomic function or vasovagal reactions compared to normal controls?
Absolute Event Rate: 25% vs 0%
Patients with paroxysmal atrial fibrillation exhibit a heightened susceptibility to vasovagal cardiovascular responses despite having normal baseline cardiac autonomic function.
Lok et al. (1998) conducted a case-control in Paroxysmal atrial fibrillation (n=47). Paroxysmal atrial fibrillation vs. Normal control subjects was evaluated on Positive head-up tilt test. Patients with paroxysmal atrial fibrillation exhibited a heightened susceptibility to vasovagal responses, with 25% having a positive tilt test compared to 0% in normal controls.
