摘要
目的 :了解高原老年患者动态心电图 (DCG)检查时各种心律失常及最低心率情况 ;方法 :用美国惠普公司生产的HP43 42 0动态心电图系统做DCG检查 ;结果 :老年患者单发房性早搏检出率为 86.9% ,成对为 1 8.8% ,阵发性房性心动过速为 2 6.2 % ;单发室性早搏检出率为 71 .9% ,成对为 2 8.0 % ,阵发性室性心动过速的检出率为 7.5 % ;最低心率为 3 7次 /分～ 99次 /分 ,小于 40次 /分者 2例 ( 2 .4% ) ,最低心率并不随年龄增长而减慢 ;结论 :上述两种早搏检出率明显高于海平面老年前期健康人组 ,最低心率并不随年龄增长而减慢 ,心率波动范围亦非为窄 ,最低心率 <40次 /分并伴有最快心率 <1 0 0次 /分 ,应采取必要措施 。
To study the incidence of arrhythmia and the minimal heart rate in senile patients.Method:107 subjects were detected by 24 hours dynamic ECG using HP43420 ECG system union,made in USA.Results:The rate of incidence of single auricular escape was up to 86.9% and the paired rate of 18.8%;26.2% of cases had the paroxysmal superventricular tachycardia (SVT).The single ventricular escape occured in 71.9% of cases and paired rate of 28.0%,7.5% paroxysmal ventricular tachycardia occured only in subjects.The minimal heart rate was ranged from 37(2 cases) to 99 beat per minute.The increase of minimal heart rate don't associated with increased age.Conclusion:The incidence of escape of heart is higher in senile patients at high altitude than that in sea level.The examination of minimal heart rate is important to protecting the heart accidents at high altitude.
