探讨房室旁道 (简称房道 )和房室结双径引起的折返性心动过速的初次发病年龄。 15 5例旁道和房室结双径引起的折返性心动过速中 ,房室折返性心动过速 (AVRT) 10 6例、房室结折返性心动过速 (AVNRT) 4 9例。根据年龄和心动过速病程推算初次发病年龄 ,然后比较AVRT和AVNRT、左和右侧旁道并AVRT、显性和隐匿性旁道并AVRT、男性和女性心动过速患者的初发年龄。结果 :AVRT和AVNRT的初发年龄分别为 2 9.9± 12 .85岁和 32 .33±11.84岁 ,组间比较无显著性差异。左、右侧旁道并AVRT、显性和隐匿性AP并AVRT、男性和女性心动过速患者初发年龄比较差异均无显著性 ,均是 30岁左右。结论 :30岁左右是AVRT和AVNRT初次发病的高发年龄段 ,其他年龄段呈散在发病
To explore the first onset age of reentrant tachycardia caused by atrioventricular bypass (aka room) and atrioventricular nodal pathways. Fifty-five cases of reentrant tachycardia caused by accessory pathways and atrioventricular nodal origin had 106 AVRTs and 49 AVNRTs. The age of onset was estimated based on the age and duration of tachycardia. AVRT and AVNRT, AVRT in the left and right sides and AVRT in the dominant and occult paracancer were compared with those of the male and female tachycardia. Results: The initial onset ages of AVRT and AVNRT were 29.9 ± 12.85 years and 32.33 ± 11.84 years respectively, with no significant difference between the two groups. Left and right bypass and AVRT, dominant and occult AP and AVRT, male and female tachycardia patients with no significant difference in the age of onset, are about 30 years old. Conclusion: The age of 30 is the high incidence of the first onset of AVRT and AVNRT, and other age groups were scattered
