An analysis was made of the changes in ECG in 61 random patients during status asthmaticus. It was found that a statistically significant increase occurred in the amplitude of the P wave in the inferior leads. P. pulmonale was noticed in lead II in 26%, in lead III in 18%, and in lead aVF in 25% during status asthmaticus, whereas corresponding values in the controls were 5%, 5% and 3%. A tendency to rS was also seen in the precordial leads, as were a small clockwise rotation, a small rotation of the frontal QRS axis to the right, and slight changes in the ST segment and T wave.
对61例哮喘持续状态患者的心电图变化进行了分析。结果发现，下壁导联P波振幅有统计学意义的增加。哮喘持续状态时，Ⅱ导联出现肺型P波的比例为26%，Ⅲ导联为18%，aVF导联为25%，而对照组相应比例分别为5%、5%和3%。胸前导联还出现rS倾向，以及轻微的顺钟向转位、额面QRS电轴轻度右偏，ST段和T波也有轻微改变。
