Tall peaked t waves-rationale: a serum potassium level higher than 5.1 meq/l indicates hyperkalemia. electrocardiographic changes include flat p waves, prolonged pr intervals, widened qrs complexes, and tall peaked t waves.test-taking strategy: from the information in the question, you need to determine that this condition is a hyperkalemic one. from this point, you must know the electrocardiographic changes that are expected when hyperkalemia exists. if you had difficulty with this question, review the normal serum potassium level and the electrocardiographic changes that occur in hyperkalemia.
