Friedman总结低血钾的心电图改变如下: 1、T波低平、平坦或倒置,合并有T波增宽,偶见T波出现切迹。 2、Q—T间期通常处于正常上限或稍延长。 3、ST段压低,常呈盆状改变,也可出现类似由洋地黄引起的改变。测量Q—T间期可作鉴别,如缩短,考虑由毛地黄引起;如延长,考虑由低血钾引起。 4、如以前无U波,低血钾时可出现U波;如
Friedman summary of hypokalemia ECG changes are as follows: 1, T wave low flat, flat or inverted, combined with T wave broadening, occasionally T wave notch appears. 2, Q-T interval is usually in the normal upper limit or slightly extended. 3, ST segment depression, often basin-like changes can also be caused by similar changes caused by digitalis. Measurement of Q-T interval can be used for identification, such as shortening, consider the yellow ground fever caused; such as prolonged, consider the hypokalemia caused. 4, U wave as before, hypokalemia may appear U wave;
