采用食道心房调搏（ＴＥＡＰ）研究５０例病态窦房结综合征（ＳＳＳ）患者年龄与房窒交界区功能障碍的关系。结果表明：＜４０岁组与～６０岁组比较，房室交界区功能障碍发生率差异无显著性（Ｐ＞０．０５），但＞６０岁组发生率明显高于＜６０岁组（Ｐ＜００５）。隐性ＡＶＢ的发生率在各年龄组无明显差异。提示：病窦患者有较高的隐性ＡＶＢ的发生率，但与年龄无关。而房室交界区起搏功能障碍则常出现于６０岁以上患者。
The relationship between the age of 50 patients with sick sinus syndrome (SSS) and dysfunction of atrial septal junction was studied by esophageal atrial pacing (TEAP). The results showed that there was no significant difference in the incidence of atrioventricular junctional dysfunction between the age of 40 years and the age of 60 years (P> 0.05), but the incidence of> 60 years old group was significantly higher than that of the 60 years old group (P <005). The incidence of latent AVB was not significantly different in all age groups. Tip: sick sinus patients have a higher incidence of latent AVB, but not with age. Atrioventricular junctional pacing dysfunction often occurs in patients over the age of 60.
