Electrolytes and the electrocardiogram

The American Journal of Cardiology, 1963
Abstract Variation in concentration of potassium and calcium ions in the extracellular fluid produce specific and well defined changes in the shape and duration of the transmembrane action potential in single myocardial fibers. These changes are responsible for typical electrocardiographic patterns encountered in patients with abnormal plasma ...

Electrolyte Balance

International Journal of Technology Assessment in Health Care, 1991
The kidney is structurally and biochemically immature at birth. As a consequence, renal function is low (3;10;ll;18). Glomerular filtration rate (related to body surface area or to body weight) is approximately 25% of that in adults. The capacity of several different tubular transport systems is lower in the infant than in the adult (2;5;13;21;28).

Electrolyte Disorders

Veterinary Clinics of North America: Small Animal Practice, 2001
Abnormal electrolyte concentrations occur commonly in hospitalized patients and may produce a variety of clinical symptoms, cause lack of response to therapeutics for primary clinical conditions, and affect clinical outcome. Recognition of electrolyte disturbances requires a high index of suspicion by the clinician for such a disturbance and prompt ...

Oscillating electrolytes

ELECTROPHORESIS, 2006
AbstractChemical oscillations are driven by the gradient of the chemical potential so that they can appear in systems where the substances are not in chemical equilibrium. We show that under the influence of the electric field, concentrations of electrically charged substances in solutions can oscillate even if the system is in chemical equilibrium ...

Urinary Electrolytes

Emergency Medicine Clinics of North America, 1986
Urinary electrolytes can be a useful tool in the Emergency Department. For those patients with volume depletion, acute oliguria and hyponatremia, the determination of urinary sodium levels can aid in diagnosing the etiology of the presenting condition. Urinary potassium levels can aid the clinician in determining the cause of the potassium loss, either
