Hyperkalemia manifests as vague muscle weakness initially, with skeletal muscle weakness possibly progressing to paralysis, paresthesias, and dysrhythmias. Hypercalcemia presents as dysrhythmia, hypertension, muscle weakness, depressed reflexes, and altered states of consciousness progressing to coma. Hypermagnesemia causes weakness, diminished deep-tendon reflexes, muscle weakness, and hypotension with peripheral vasodilation.
