老年高血压患者心律失常特点及其与左室肥厚的关系

Prevalence of Arrhythmias and its Relations with Left Ventricular Hypertrophy in Elderly Hypertensive Patients

分析原发性高血压病226例（老年组139例，非老年组87例）和80例健康老年人（对照组）24h动态心电图检测的心律失常。结果示总房性和室性心律失常发生率在高血压老年组为97％和77％，非老年高血压组为85％和53％，对照组为89％和59％；其中阵发房速、房颤和Lown's分级≥3的室性心律失常在高血压老年组达47％和40％，非老年组21％和22％，对照组30％和11％（P＜0．05～0．001）。在高血压老年组中62例伴左室肥厚（LVH），其总室住心律失常发生率和town's分级≥3者达92％和57％，均高于无LVH者的65％和27％（P＜0．001）。提示其发生与LVH密切相关。

The prevalence and significance of arrhytboias de-tected by 24 h ambulatory electrocardiographic monitoring were stud-ied in essential hypertensive petients (elderly group: 139 cases, ase>60; adult group: 87 cases ) and elderly healthy volunteers (con-trol group: 80 cases ). The incidences of total atrial and ventriculararrhythmias were 97% and 77% in elderly group, 85% and 53%in adult group, 89% and 59% in control group; paroxymal atrialtachycardia and atrial fibrillation and town's grade > 3 ventriculararrhythmias were 47% and 40% in elderly group, 21 % and 22%in adult group, 30% and 11 % in control group (P< 0. 05- 0. 001,respetively). In elderly hypertensive potients, 62 cases with leftventricular hypertrophy (LVH) and 77 cases without LVH, the inci-dences of total ventricular arrhythmias (VA) and VA with town'sgrade >3 were 92% and 57% vs 65% and 27% respectively (P<0. 001 respetively). The results suggests that arrhythmias often oc-cur in hypertinsive patients and have an increased tendency in the el-derly; in peticular, ventricular arrhythmia asems clerely related toLVH.
