Blood Normal potassium levels are between 3.5 and 5.0 mmol/L with levels below 3.5 mmol/L (less than 3.5 mEq/L) defined as<unk> . Electrocardiogram<unk>  leads to characteristic ECG changes (PR prolongation, ST-segment and T-wave depression, U-wave formation). The earliest electrocardiographic (ECG) findings, associated with<unk> , are decreased T wave height. Then, ST depressions and T inversions appear as serum potassium levels reduce further. Due to prolonged repolarization of ventricular Purkinje fibers, prominent U waves occur (usually seen at V2 and V3 leads), frequently superimposed upon T waves, therefore producing the appearance of prolonged QT intervals, when serum potassium levels fall below 3 mEq/L. Amount The amount of potassium deficit can be calculated using the following formula: Meanwhile, the daily body requirement of potassium is calculated by multiplying 1 mmol to body weight in kilograms. Adding potassium deficit and daily potassium requirement would give the total amount of potassium need to be corrected in mmol. Dividing mmol by 13.4 will give the potassium in grams.
