Abstract
Background: Hypokalemia with ECG changes is very hazardous; therefore, it is important to correct hypokalemia to avoid life-threatening cardiovascular complications.
Objective: To know ECG pattern pre and post potassium correction in patients with hypokalemia.
Methods and results: A prospective study with longitudinal observational design in hospitalized hypokalemic patients who received intravenous potassium correction at Dr. Wahidin Sudirohusodo Hospital, Makassar during February - May 2018. ECG changes are determined based on ECG examination. Potassium correction is given based on potassium deficit formula. Data analysis used SPSS version 22 with McNemar and Chi Square statistical test. Study included 80 subjects consisting of 26 males and 54 females, mean age of 48,8 ± 16 years, 53,8% of moderate and 38,8% of severe hypokalemia, 85% having ECG changes. The ECG patterns were long QT (30%), prominent U (30%), T-inverted (21,2%), ST depression (15%), T-flat (10%), VES (6,3%), SVT (3,8%), first degree AVB (3,8%), and AF (2,5%). Significant improvement found in long QT and prominent U post correction (p<0.05). Decrease of post correction potassium levels, found 100% of prominent U and 75% of long QT became normal.
Conclusion: The ECG patterns in hypokalemia are mostly long QT and prominent U. Potassium correction may provide an improvement in ECG patterns even if potassium levels still below the normal range.

Key words: ECG, hypokalemia, arrhythmia, long QT, prominent U
