<prompt> Which of the following is NOT TRUE about ECG changes in hyperkalemia?Peaked P-wavePeaked T -waveSinusoidal shape complexBroad QRS Complex  <response>: With mild to moderate hyperkalemia, there is reduction of the size of the P wave and development of peaked T waves. Severe hyperkalemia results in a widening of the QRS complex, and the ECG complex can evolve to a sinusoidal shape.
