Potassium is the principal intracellular cation, and maintenance of the distribution of potassium between the intracellular and the extracellular compartments relies on several homeostatic mechanisms. When these mechanisms are perturbed, hypokalemia or hyperkalemia may occur.

Pseudohyperkalemia, or factitious hyperkalemia, constitutes an artificially high plasma potassium level (P(K)) from a variety of possible causes. Occasionally, the cause cannot be elucidated. Three patients who showed unusually large differences between free-flowing and tourniquet (stasis) potassium levels prompted us to investigate the influence of ...

To the Editor.— In his Letter, 1 Dr Hoyt speculates that therapy with the calcium antagonist diltiazem may have exacerbated hyperkalemia in a 70-year-old patient treated with metoprolol who was consuming massive quantities of potassium as salt substitute.

Pediatrics In Review, 1996
Potassium is the major intracellular cation; only a very small fraction of total body potassium is in the intravascular space. Increased potassium concentration in serum is infrequent in pediatrics, but it can be life-threatening because of its effect on membrane potentials, particularly of heart muscle.

We have described three patients with diabetes and renal insufficiency who had hyperkalemia during heparin therapy. These cases lend support to previous findings, and emphasize the clinical importance of this entity. We believe that heparin-induced hyperkalemia is a potentially life-threatening problem that is more common than previously appreciated ...

Hyperkalemia in Hemodialysis Patients
Seminars in Dialysis, 2014Hyperkalemia contributes significantly to high mortality among ESRD patients. Excess intake and inadequate removal are the most common etiologies in HD patients. Although dialysis is the definitive treatment, classical medical therapy must be employed as a temporizing measure to acutely lower serum potassium.

Physiologic and pathologic events that occur in patients as they grow older may result in distal renal tubular dysfunction, as well as decreased levels of plasma renin activity and plasma aldosterone. Such alterations result in a tendency toward hyperkalemia.

Hyperkalemia is a potentially fatal condition and is defined by a serum potassium level (K+) of greater than 5.5 mmol/L. The associated prevalence of cardiac arrhythmia increases directly with the degree of hyperkalemia. The danger in the majority of hyperkalemia cases is cardiac dysrhythmia, and often ventricular fibrillation or asystole is the ...
