On the mechanism of rhabdomyolysis in potassium depletion.
Rhabdomyolysis and myoglobinuria occur commonly in men who sustain environmental heat injury during intensive physical training in hot climates. These also occur in patients with potassium depletion. Since physical training in hot climates may be accompanied by serious losses of body potassium, the possibility was considered that performance of strenuous exercise when potassium deficient might ...
متن کاملPotassium depletion and diastolic dysfunction.
Changes in extracellular potassium concentration affect nearly all aspects of myocardial function. Reductions in potassium concentration alter the resting membrane potential, membrane conductance for sodium and potassium, repolarization time, relative refractory time, and conduction velocity. The arrhythmogenic consequences of these effects of potassium depletion are well recognized by the medi...

متن کاملPotassium depletion improves myocardial potassium uptake in vivo.
Potassium depletion (KD) is a very common clinical entity often associated with adverse cardiac effects. KD is generally considered to reduce muscular Na-K-ATPase density and secondarily reduce K uptake capacity. In KD rats we evaluated myocardial Na-K-ATPase density, ion content, and myocardial K reuptake. KD for 2 wk reduced plasma K to 1.8 +/- 0.1 vs. 3.5 +/- 0.2 mM in controls (P < 0.01, n ...
متن کاملDepletion of body potassium by diuretics.
THE occurrence of ulcers in the small intestine during the course of treatment of patients with thiazide diuretics together with enteric-coated tablets of potassium chloride or enteric-coated tablets of combinations of thiazides and potassium chloride has suggested to several investigators that some factor in these medications may be responsible for the genesis of such ulcers.1' 2 As a matter o...
