[Electrocardiogram Minnesota codings from 30 000 adult cases with Kazakh ethnicity in Xinjiang, China].

ABSTRACT

OBJECTIVE: To observe the abnormal Minnesota code (MC) distribution and interrelated characteristic on electrocardiograms (ECGs) of the adult Kazakh population. METHODS: Resting ECGs and blood press of randomly sampled 30 000 adult Kazakh people in three Northern regions of Xinjiang were continuously examined and analyzed, using Minnesota code recommended by WHO as the classification of ECG. RESULTS: The overall rate of abnormal ECG findings was 248.60 per thousand, and the main abnormality in males was 146.83 per thousand, compared to 157.71 per thousand in females. The prevalence rates of abnormal ST-T changes, the total arrhythmia and atrial fibrillation (AF) were 100.03 per thousand, 71.17 per thousand and 2.83 per thousand respectively. There were statistically significant differences among the main abnormities from the three regions. CONCLUSION: The ECGs abnormalities of adult Kazakh people were high. There was significant relation found between the main abnormalities and hypertension. The prevalence of AF was different from the domestically reported literature that calls for further study.
