本文分析慢性高原病合并左前分支阻滞60例,将其分为单纯型、合并型、电轴变动型,混合型4组。单纯型在高原红细胞增多症中占55％,其他三型多见于临床症状较重的高原心脏病,高血压患者。在高原三年内心电图动态观察,60例无1例恢复正常,随访回到平原12例,五年内在高红症5例中ECG恢复2例,7例心脏病患者有一例ECG恢复正常,2例(LAH混合型)被确诊为冠心病。通过各类型LAH与临床对比和联系,探讨慢性高原病合并各类型LAH的临床意义。
In this paper, 60 patients with chronic high altitude sickness complicated with left anterior branch block were divided into four groups: simple type, merge type, variable axis type and mixed type. Simplex in 55% of high altitude polycythemia, the other three more common in clinical symptoms of plateau heart disease, hypertension. During the three years of plateau electrocardiogram dynamic observation, none of 60 cases returned to normal, followed up to plain 12 cases. Within 5 years, 5 cases of hyperlipidemia recovered 2 cases of ECG, 7 cases of heart disease, 1 case of ECG returned to normal, 2 cases (LAH mixed type) was diagnosed with coronary heart disease. Through various types of LAH and clinical comparison and contact, to explore the clinical significance of various types of LAH in patients with chronic high altitude disease.
