Elevated potassium level is a common and life threatening condition that is seen in the emergency department. Hyperkalemia is defined as a serum K of greater than 5.5. In order to reduce morbidity and mortality associated with this condition, early identification and treatment is key. It is important to recall that potassium is a primarily intracellular cation. When there is excess extracellular potassium, either from shifts or inability to excrete, patients can experience arrhythmias and potentially cardiac arrest.
What is an EKG?
An electrocardiogram (EKG) is often times obtained on patients shortly after they arrive in the emergency department. This EKG can be used to evaluate for ischemic changes, but also can give the provider some early insight into the patient’s electrolyte levels. A combination of clinical history paired with EKG findings consistent with elevated potassium levels, should prompt emergent treatment to stabilize the cardiac membrane.

EKG changes vary depending on the severity of the hypokalemia, however there is no a direct correlation with serum potassium levels.
Does hypokalemia cause hyperpolarization?
Symptoms associated with hypokalemia are correlated not only with serum potassium levels, but also with the rate of increase in potassium concentration. Low serum potassium levels provoke cell membrane hyperpolarization, which causes the clinical manifestations 4. Mild hypokalemia rarely causes symptoms.
