Objective To investigate autonomic nervous activities in patients with gagging problem. Methods Subjects were 12 and 12 individuals, graded as Group G2 (mild gagging problem) and Group G3 (middle gagging problem), respectively, according to the Classification of Gagging Problem index (CGP) and compared with 15 normal patients. Heart rate (HR), low‐frequency/high‐frequency ratio (L/H), the coefficient of component variation for high frequency (CCVHF), and the coefficient of variation of R‐R intervals (CVRR) were assessed by heart rate variability on electrocardiogram. The measurement was recorded continuously for 1 min before and after dental mirror insertion. Results The insertion did not affect HR, L/H, CCVH, and CVRR in Group G2. HR did not change despite both increases in L/H and CCVHF after the insertion in Group G3. Conclusions Patients with a gagging problem in G3, dental mirror insertion increased both parasympathetic and sympathetic nervous activities, despite no change in HR.
