All of the following may occur due to hypokalemia, except-
ECG changes when K+ < 2.7 mmol/l Increased amplitude and width of the P wave Prolongation of the PR interval T wave flattening and inversion ST depression Prominent <a href=" waves</a> (best seen in the precordial leads) Apparent long QT interval due to fusion of the T and U waves (= long QU interval) With worsening hypokalaemia... Frequent supraventricular and ventricular ectopics Supraventricular tachyarrhythmias: AF, atrial flutter, atrial tachycardia Potential to develop life-threatening ventricular arrhythmias, e.g. VT, VF and Torsades de Pointes Ref Davidson 23rd edition pg 361
