摘要
目的探讨动脉舒张压中的变音现象,为更准确地测量血压提供一定的临床试验依据。方法整群抽样内科门诊的就诊患者100名,袖带法测定血压,分别记录舒张压中变音和消失音时的血压值,进行统计分析。结果舒张压中出现变音现象的发生率为40%,老年、高血压被检者的舒张压变音发生率显著高于中青年及非高血压人群,与舒张压变音现象具有正关联的因素主要为年龄因素,老年人发生舒张压变音现象的可能性显著高于中青年。结论测量血压时需要考虑舒张压的变音现象,尤其对于老年、高血压被检者可能更适宜取变音值作为舒张压值。
Objective To explore the fourth korotkoff sound of diastolic blood pressure, in order to examine blood pressure more exactly. Methods 100 patients from out-patient department were entirely taken their blood pressure with blood pressure cuffs, the fourth and fifth korotkoff sounds were recorded and analysed. Results 40 percent of the fourth korotkoff sound was examined. The occurrence rate of the fourth korotkoff sound in elders and hypertensive patients was larger than that in youngers. The fourth korotkoff sound was positively associated with the age factor. Conclusions The fourth korotkoff sound should be considered in Mood pressure measursing, the value of the fourth korotkoff sound might be more suitable for diastolic blood pressure especially in elders and hypertensive patients.
