Clinical Characteristics of Defecation and Micturition Syncope Compared with Common Vasovagal Syncope

Background: Little is known about the clinical characteristics of patients with situational syncope such as defecation syncope (DS) or micturition syncope (MS) compared with those with common vasovagal syncope (VVS). Methods: Among 680 consecutive patients, who underwent a head‐up tilt test between...

Description
Summary:	Background: Little is known about the clinical characteristics of patients with situational syncope such as defecation syncope (DS) or micturition syncope (MS) compared with those with common vasovagal syncope (VVS). Methods: Among 680 consecutive patients, who underwent a head‐up tilt test between January 2006 and November 2010, 282 patients (40.4±16.7 years; 48.6% men) diagnosed as DS (n = 38), MS (n = 38), or common VVS (n = 208) were included. Results: Ages at diagnosis (38.7±17.3 vs 48.3±14.1 vs 42.0±13.8, P = 0.004) and the first syncope (33.7±18.4 vs 44.5±15.3 vs 37.5±14.6, P = 0.002) were significantly less in patients with common VVS than those with DS or MS, respectively. The patients with MS were more likely to be men (73.7%, P = 0.036), whereas patients with DS were more commonly women (73.7%). No sexual preference was observed in patients with common VVS. Body mass index was significantly lower (P = 0.047) and syncopal episodes were more recurrent (P = 0.049) in patients with common VVS than those with DS or MS. The frequency of drinking alcoholbefore syncope was significantly higher in patients with MS (39.5%, P < 0.001). Conclusions: DS tended to occur in older women, whereas MS tended to occur in middle‐aged men and drinking alcohol was an important precipitating factor for MS. However, common VVS was observed more in a thin and young population, which was more recurrent compared with those situational syncopes. (PACE 2011;1–7)
