高原心脏病24小时动态心电图13例分析

THE HOLTER ANALYSIS IN 13 CASES WITH HIGH ALTITUDE HEART DISEASE

对１３例轻度高原低氧性肺动脉高压者进行了２４小时动态心电图（ＨＯＬＴＥＲ）观察。观察结果与同期１０例健康人和９例心血管病人进行了比较，结果发现：高原低氧性肺动脉高压者的平均心率、最慢心率、最快心率、室性早搏次数、房性早搏次数与健康人相比无统计学差异，但其心率变异指数低于健康人，这说明轻度高原低氧性肺动脉高压者并无明显心律失常倾向，但其自主神经调节功能可能不稳定。

he Holter monitoring in 13 cases with high altitude heart disease(HAHD)were studied.Theresults were compared to 10 healthy high altitude immigrants(HHAI).The total heart beat,meanheart rate,the lowest heart rate,the fastest heart rate,ventricular premature beat,atrial prema-ture beat in HAHD were 68 010～119 316,50～84,36～61,80～174,0～74and 0～31;in HHAIwere 74 150～113 843,53～80,39～60,92～-169,0～22and 0～51,respectively.The difference be-tween the two groups was not statistically significant. Ventricular premature beats were detectedin 8 cases of 13 HAHD(61.5%),6 cases belonged to 1A,1 case to 1B and 1 case to 4 grade andin 6 cases of 10 HHAI(60%),5 cases belong to 1A and 1 case to 4 grade according to Lown'sclassification.The lowest heart rate in HHAD was 36 and in HHAl was 39,both were sinus rythy-m.There were no 1 or 2.degree AVB and other serious arrythymias detected
