Hypomagnesemia is often times associated with hypokalemia; thus it is important to check a magnesium level in any patient who presents with arrhythmia. Severe hypokalemia with EKG changes should be treated emergently with repletion with intravenous potassium chloride to a K of 4-4.5.


ECG should be done on patients with hypokalemia. Cardiac effects of hypokalemia are usually minimal until serum potassium concentrations are < 3 mEq/L (< 3 mmol/L). Hypokalemia causes sagging of the ST segment, depression of the T wave, and elevation of the U wave.

In a retrospective review, blinded cardiologists documented peaked T-waves in only 3 of 90 ECGs with hyperkalemia. Sensitivity of peaked-Ts for hyperkalemia ranged from 0.18 to 0.52 depending on the criteria for peak-T waves. [medical citation needed] Prevention Hyperkalemia is a higher than normal level of potassium in the blood. Although mild cases may not produce symptoms and may be easy to treat, severe cases can lead to fatal cardiac arrhythmias. Learn the symptoms and how it's treated. Treat hypokalemia Hypomagnesemia causes hypokalemia. It is often the combination of these two abnormalities that causes arrhythmia.

Although the chronic hypokalemia can be mildly symptomatic, it can be aggravated by diarrhea or vomiting, precipitating prolonged QT interval, increased risk of rhabdomyolysis, cardiac arrhythmia, syncope and sudden death.

The electrocardiographic criteria for hypokalemia include the presence of U waves greater than 1 mm and U waves larger than the T wave in the same lead (with associated ST-segment depression). ECG findings in hypokalemia: Kalium cca 3,0–3,8 mmol/l: Flattening or inversion of T waves.

Hypokalemia arrhythmia ecg

Hypokalemia is associated with a wide range of arrhythmias, including atrial and ventricular extrasystoles, atrial fibrillation, and torsades de pointes ventricular tachycardia. The ECG signs of hypokalemia are described in Chapter 32.

Arrhythmias may occur already at therapeutic plasma levels of digoxin in the setting of hypokalemia. Arrhythmias caused by digoxin INTRODUCTION. Although hypokalemia can be transiently induced by the entry of potassium into the cells, most cases result from unreplenished gastrointestinal or urinary losses due, for example, to vomiting, diarrhea, or diuretic therapy [].
