老年退行性心脏瓣膜病心脏传导阻滞的分析

摘要

Objective: To investigate characteristics of heart conduction block in patients with senile degenerative heart valvular disease (SDHVD). Methods: Dynamic electrocardiography was performed in 400 SDHVD patients and 189 aged patients without SDHVD. Characteristics of heart conduction block were compared between the two groups. Results: Compared with non-SDHVD patients, incidence rates of sinoauricular block (1. 6% vs. 5.0%) and complete right bundle branch block (CRBBB, 3. 2% vs. 7. 5%) significantly increased in SDHVD patients, P< 0.05, both; among SDHVD patients, incidence rate of sinoauricular block in SDHVD + coronary heart disease group was significantly higher than that of pure SDHVD group (6. 9% vs. 2. 0%) , incidence rates of sinoauricular block (14. 3% vs. 4. 3%) and CRBBB (21. 4% vs. 6. 5%) in aortic degeneration complicated mitral degeneration group were significantly higher than those of pure aortic degeneration group (P<0. 05 all). Conclusion: Incidence of heart conduction blocks increase in SDHVD patients. It is suggests that SDHVD patients should be regularly checked using dynamic electrocardiography to detect abnormal change in time, make necessary intervention and improve prognosis.%目的:探讨老年退行性心脏瓣膜病(SDHVD)患者心脏传导阻滞特点.方法:选择SDHVD患者400例,无SDHVD老年患者189例,均行动态心电图检查,比较组间心脏传导阻滞特点.结果:与无SDHVD患者比较,SDHVD患者窦房传导阻滞(1.6％比5.0％)、完全性右束支传导阻滞(3.2％比7.5％)发生率显著增加(P均＜0.05)；在SDHVD患者中,SDHVD合并冠心病组窦房阻滞发生率较单纯SDHVD组显著增加(6.9％比2.0％),主动脉退变合并二尖瓣退变组较单纯主动脉退变组窦房传导阻滞(14.3％比4.3％)、完全性右束支传导阻滞(21.4％比6.5％)发生率显著增加(P均＜0.05).结论:老年退行性心脏瓣膜病患者心脏传导阻滞增加,建议对此类患者定期行动态心电图检查,及时发现改变并进行必要的干预,改善预后.
