title: ECG changes of hyperkalemia during paced rhythm.
abstract: 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.
