Investigation Ofxinjiangregion Health Adults QRS Duration

Objective:To investigate the xinjiang region health adults QRS duration distribution and its gender,age,ethnic differences,comparing it with the international standard. Methods:using simple random sampling method,collected4750cases healthy people electrocardiogram of xinjiang adults,2277cases (47.94%) men,and2473cases (52.06%)women, and according to the gender is divided into six age groups, and calculate each age groups mean QRS duration upper limit and lower limit value. Results:(1) The mean QRS duration of men is (94.00±10.48) ms, women is (86.54±9.85) ms, the mean QRS duration and the uppe、lower limit of men were higher than women,(p<0.01), gender difference was statistically significant; After the70-year old men and women QRS duration were rising trend, the other ages basically stable;(2) The correlation coefficient r the relationship QRS duration between age and heart rate is0.031and0.019,(p>0.05), the QRS duration with no statistically significant difference between age and heart rate;(3)The uighurs mean QRS duration (94.01±9.47),the hans is (94.01±9.47),and uyghurs higher than hans,(p<0.01), the difference was statistically significant between the two ethnic groups。conclusion:Xinjiang region healthy adult population QRS duration is not consistent with the international standard, and there is an obvious gender and ethnic differences, it is necessary to establish the normal standards of associated with age and sex. Adjust the traditional normal QRS duration limit standard, is expected to further improve the quality of electrocardiogram diagnosis.
