目的介绍心电轴计算公式,通过对公式法与查表法比较,说明公式法的实用有效。方法介绍心电轴计算公式及其原理,应用公式法制定心电轴表记作表1,将表1中的数值与表2中的数值进行配对设计以及对40例心电图实例应用上述两种方法所得值进行配对设计。结果对配对样本t检验的结果(P>0.05)表明这两种方法无显著差别,公式法与查表法取得一致性结果。结论公式法是一种准确实用的方法。
Objective To introduce the calculation formula of ECG axis, and to compare the formula method with the look-up table method, which shows that the formula method is practical and effective. Methods The formula and principle of ECG axis were introduced. The formula of ECG axis was formulated as Table 1, the values in Table 1 were matched with the values in Table 2, and the above two methods were applied to 40 ECG examples The value of the paired design. The results of the paired sample t-test results (P> 0.05) showed that there was no significant difference between the two methods, the formula method and the table look-up method to achieve consistent results. Conclusion Formula method is an accurate and practical method.
