The following ECG findings are seen in Hypokalemia
Effects of hypokalaemia on the ECG Changes appear 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 Ref Harrison 20th edition pg 1456
Increased PR interval with ST depression
Increased PR interval with peaked T wave
Prolonged QT interval with T wave inversion
Decreased QT interval with ST depression
