血管迷走性晕厥的诊断现状

Diagnosis of vasovagal syncope

血管迷走性晕厥的诊断主要依靠典型的临床症状,直立倾斜试验是主要的辅助诊断手段,但诊断敏感性和特异度有限。近年来心率减速力是新出现的诊断技术,可能有助于血管迷走性晕厥的诊断,但需要多中心、更大人群的验证。

The diagnosis of vasovagal syncope mainly depends on the typically clinical symptoms now.The tilt table test is the key diagnostic tool for vasovagal syncope,but its sensitivity and specificity is limited.Deceleration capacity has been demonstrated useful in the diagnosis of vasovagal syncope yet large scale and multicenter studies are required to confirm the value of deceleration capacity.
