The autonomic mechanism that triggered atrial fibrillation in a patient during tilt test was investigated. Neurocardiogenic syncope is often characterized by diminished baroreflex sensitivity during the hypotension period. Increased barorereflex sensitivity preceding the onset of atrial fibrillation in tilt testing may indicate the involvement of a vagally mediated mechanism, as shown in the present case.
对一名患者在倾斜试验期间引发心房颤动的自主神经机制进行了研究。神经心源性晕厥的特点通常是在低血压期压力反射敏感性降低。如本病例所示，倾斜试验中心房颤动发作前压力反射敏感性增加可能表明存在迷走神经介导的机制。
