OBJECTIVE: To study the clinical features and intervention strategies of head-up tilt table test (HUTT) induced syncope triggering convulsion. METHODS: HUTT was performed in 2377 cases (male 1116 cases and female 1261 cases) with syncope, dizziness, headache, chest tightness at Second Xiangya Hospital of Central South University from September 2000 to August 2011. They were 2.00-78.00 (18.57±14.36) years old, 1719 cases were younger than 18 years (the children group) [(2.00-17.92 (10.88±3.02) years] and 658 were older than 18 years (the adult group) [(18.00-78.00 (38.66±12.87) years]. We analyzed the related factors for inducing syncope triggering convulsion symptom and other serious side effects in HUTT. RESULTS: 1) Eighty-nine patients (3.74%) induced syncope with convulsion symptoms during HUTT, with more adults (62.92%) than children (37.08%) (χ(2)=87.842, P<0.01). 2) Sinus cardiac arrest and heart rate recovery time: 25 (28.09%) out of the 89 patients had sinus cardiac arrest. The sinus cardiac arrest time was 3.00-14.60 (7.90±3.44) s. After the HUTT, the heart rate recovery time was 0.50-37.00 (3.05±4.11) min, 70 of which (78.65%) resumed 3 min. 3) INTERVENTIONS: when all patients completed the HUTT, they would take oxygen and drink milk and other measures to relieve convulsions and recover heart rate and blood pressure. No one died, and the vital signs of 2 patients returned to normal after intravenous administration. CONCLUSION: Induced syncope triggering convulsion symptom in HUTT is more common in adult patients. Convulsions disappear and heart rate and blood pressure return to normal after taking oxygen and milk and other measures. HUTT in clinical practice is safe, and can be used in patients of all ages.
