Paced rhythms can mask ECG changes of several conditions. ECG changes due to hyperkalemia during paced rhythm have not been well described. We report a patient with isolated noncompaction of left ventricle with left ventricular dysfunction and complete heart block on a permanent pacemaker who developed hyperkalemia. Typical ECG changes of hyperkalemia including widening of QRS complex and sine waves were seen even during paced rhythm that reverted with correction of hyperkalemia.
起搏心律可掩盖多种疾病的心电图变化。关于起搏心律时高钾血症所致的心电图变化，目前尚无详尽描述。我们报告一例患有孤立性左心室心肌致密化不全伴左心室功能障碍且植入永久性起搏器的完全性心脏传导阻滞患者，该患者发生了高钾血症。即便在起搏心律期间，也出现了高钾血症典型的心电图变化，包括QRS波群增宽和正弦波，高钾血症纠正后这些变化消失。
