Errors in potassium measurement can lead to falsely elevated potassium level that is pseudo hyperkalemia. Usually these errors are recognized either by the clinicians or laboratory personals. The factors which causes pseudo hyperkalemia can mask hypokalemia by pushing low value to normal value, which is very difficult identify by laboratory personals. In this article we are discussing the cause...

Hyperkalemia is a common clinical condition among heart failure patients especially if there coexisting older age, potassium-sparing medication, and renal insufficiency. Close follow-up titration of renin-angiotensin-aldosterone system inhibitors are essential to prevent the development hyperkalemia. It can also cause significant abnormalities in with cardiac implantable electronic devices (CIE...

We report a case of transient hyperkalemia during hysterectomy after cesarean section, due to preoperatively undiagnosed placenta accreta that caused unforeseen massive hemorrhage and required rapid red cell transfusion. Hyperkalemia-induced by rapid red cell transfusion is a well-known severe complication of transfusion; however, in patients with sudden massive hemorrhage, rapid red cell trans...

A 76 year-old woman with a history of coronary artery bypass grafting and prior myocardial infarction was transferred to the emergency room with loss of consciousness due to marked bradycardia caused by hyperkalemia. The concentration of serum potassium was high, and normal sinus rhythm was restored after correction of the serum potassium level. The cause of hyperkalemia was considered to be se...

Regional hyperkalemia during acute myocardial ischemia is a major factor promoting electrophysiological abnormalities leading to ventricular fibrillation (VF). However, steep action potential duration restitution, recently proposed to be a major determinant of VF, is typically decreased rather than increased by hyperkalemia and acute ischemia. To investigate this apparent contradiction, we simu...

With up to 56% of individuals taking diuretics likely to develop hypokalemia, and comorbid disease and many other types of medications having the potential to induce hyperkalemia, potassium abnormalities are some of the most commonly seen electrolyte abnormalities in the emergency department (ED). Unless recognized and treated appropriately, they can also be some of the most deadly. Symptoms ac...

Bradycardia, renal failure, Atrioventricular (AV) nodal Blocker Drug Use, Shock, and Hyperkalemia (BRASH) syndrome is a clinical condition frequently seen in emergency services but with low diagnostic awareness. In cases of the syndrome, its cause was determined to be synergistic effect hyperkalemia due failure use AV blocker drugs. The common features patients diagnosed BRASH are moderately el...

BACKGROUND Perceived risks of hyperkalemia and acute renal insufficiency may limit use of mineralocorticoid receptor antagonist (MRA) therapy in patients with heart failure, especially those with diabetes mellitus or chronic kidney disease. METHODS AND RESULTS Using clinical registry data linked to Medicare claims, we analyzed patients hospitalized with heart failure between 2005 and 2013 wit...
