Abstract:
Objective:To explore diagnostic value of basic head-up tilt table test (HUT)and sublingual nitroglycerin head-up tilt table test (SNHUT)on vasovagal syncope (VVS).Methods:A total of 61 patients,who collapsed be-cause of unknown causes and were highly suspected as VVS,were regarded as VVS group,received HUT,and an-other 22 healthy subjects were regarded as healthy control group.Results:Among the 61 cases of VVS group,57 ca-ses were tilt test positive and the positive rate was 93.44%.Among them,there were 16 cases (26.23%)with posi-tive basic HUT and 41 cases (67.21%)with positive SNHUT.The 22 cases in healthy control group also received basic HUT and SNHUT,one case (4.54%)was basic HUT positive and three cases were SNHUT positive.Positive rates of SNHUT was higher than that of HUT,but there was no significant difference in VVS group (χ2 =0.175,P =0.683).Conclusion:HUT is a noninvasive,repeatable method easily accepted by patients for diagnosing VVS currently.It can elevate positive rate of test when combined with SNHUT.
