Digitalis diarrhea with

Oral Treatment of hypokalemia in the following conditions With or without metabolic alkalosis digitalis intoxication familial periodic paralysis diabetic acidosis diarrhea and vomiting surgical conditions accompanied by nitrogen loss, vomiting, suction drainage, diarrhea, and increased urinary excretion of potassium certain cases of uremia hyperadrenalism starvation and debilitation corticosteroid or diuretic therapy. 

Cardiovascular toxicity is also frequently encountered in poisoning. Hypotension may be due to depression of cardiac contractility hypovolemia resulting from vomiting, diarrhea, or fluid sequestration peripheral vascular collapse due to blockade of -adrenoceptor-mediated vascular tone or cardiac arrhythmias. Hypothermia or hyperthermia due to exposure as well as the temperature-dysregulating effects of many drugs can also produce hypotension. Lethal arrhythmias such as ventricular tachycardia and fibrillation can occur with overdoses of many cardioactive drugs such as ephedrine, amphetamines, cocaine, tricyclic antidepressants, digitalis, and theophylline.
