Cardiovascular effects. In severe cases, extensive tissue third spacing of fluids combined with fluid loss from gastroenteritis may lead to hypotension, tachycardia, shock, and death. Metabolic acidosis and rhabdomyoly-sis may be present. After a delay of 1-6 days, there may be a second phase of congestive cardiomyopathy, cardiogenic or noncardiogenic pulmonary edema, and isolated or recurrent cardiac arrhythmias. Prolongation of the QT interval may be associated with torsade de pointes ventricular arrhythmia.
