Electrolyte disorders can alter cardiac ionic currents kinetics and depending on the changes
can promote proarrhythmic or antiarrhythmic effects. The present report reviews the …

The focus of this article is hypokalemia, its electrophysiologic properties, and clinical
arrhythmias. The effects of potassium on the electrophysiologic properties of the heart have …

While a number of electrolytes play a role in the genesis of the transmembrane action
potential (AP), the changes in the action potential most clearly related to arrhythmias are …

Hypokalemia is a common biochemical finding in cardiac patients and may represent a side
effect of diuretic therapy or result from endogenous activation of renin–angiotensin system …

It is well known that changes in serum potassium cause ventricular arrhythmias as a result of
clearly documented changes in the electrophysiological characteristics of single fibers …

Increasing information on the potentially serious risks of potassium and magnesium
depletion associated with diuretic therapy demands a clinical focus on understanding the …

Hyperkalemia is a common clinical condition that can induce deadly cardiac arrhythmias.
Electrocardiographic manifestations of hyperkalemia vary from the classic sine-wave rhythm …

Hyperkalemia is a common cause of electrolyte induced cardiac conduction disturbance. A
well-defined series of changes at the cellular level leads to characteristic evolutionary …

Routine use of diuretics and neurohumoral activation make hypokalemia (serum K+< 3. 5
mM) a prevalent electrolyte disorder among heart failure patients, contributing to the …

A growing body of experimental, epidemiologic and physiologic evidence testifies to the
hazards of hypokalemia and other electrolyte disorders that can complicate the chronic use …
