Capreomycin-induced serum electrolyte abnormalities

Capreomycin-induced serum electrolyte abnormalities.

Electrocardiographic manifestations: electrolyte abnormalities.

Because myocyte depolarization and repolarization depend on intra- and extracellular shifts in ion gradients, abnormal serum electrolyte levels can have profound effects on cardiac conduction and the electrocardiogram (EKG). Changes in extracellular potassium, calcium, and magnesium levels can change myocyte membrane potential gradients and alter the cardiac action potential. These changes can ...

Electrolyte abnormalities with a fatal implication.

A 72-year-old caucasian male presented with a 1-month history of decreased appetite, 6 kg weight loss with alteration in pattern of micturition; namely a tendency to pass most of his urine overnight, estimated at 2 l to 2.5 l. He also gave a 1-week history of progressive ankle swelling. Over this period of time he felt increasingly clumsy on his feet especially on turning abruptly. He denied fe...

Abnormal ECGs secondary to electrolyte abnormalities.

Metabolic and electrolyte abnormalities during heat exhaustion.

Accepted 27 September 1995 An 81-year-old man, resident of a poorly ventilated, ineffectively air-conditioned inner city apartment, presented during a heat wave (environmental temperature 80°-93°F and humidity 70%-80%) with hyperthermia, confusion and dehydration. The patient had mild hypertension, depression and urinary incontinence and was taking hydrochlorothiazide/methyldopa, nortriptyline ...
