  • Abstract
  • Look Inside

 The relationship between autonomic nerve function and atrial fibrillation which is induced by acetylcholine is unknown. For the diagnosis of vasospastic angina, we performed acetylcholine provocation tests in 30 patients without significant coronary stenosis. 6 patients experienced atrial fibrillation 〔17%, Af (+) group〕, 30 patients did not 〔83%, Af (-) group〕. We performed ultrasonography and 24 Holter ECG. We compared markers of left cardiac function (LAD, A/R, A/E, LVEF, LVEDP) and autonomic nerve function utilizing heart rate variability (AVRR, SDRR, CVRR, RR 50, LF, HF, LF/HF). However, there was no significant difference in the markers in the two groups. These findings suggest that the effect of autonomic nerve function on atrial fibrillation induced by acetylcholine is small and other factors such as electrophysiological disorder of the atria may play an important role.
