1. Hyperkalemia 5.9 mEq/L The T waves are peaked.   They have a broad base with a narrow apex. 2. Hyperkalemia 6.1 mEq/L  The P wave is absent.   The QRS complex remains narrow but there is a tall T wave present. 3. Hyperkalemia 6.2 mEq/L  The P wave is absent.   The QRS complex is wide and there is a tall T wave present. 4. Hyperkalemia 6.4 mEq/L 5. Hyperkalemia 6.8 mEq/L 6. Hyperkalemia 6.9 mEq/L  The PR interval is .26 sec.   The QRS complex is .10 sec.   The T waves are tall. 7. Hyperkalemia 6.9 mEq/L The P wave is absent.   The QRS complex is wide with a very peaked T wave. 8. Hyperkalemia 7.0 mEq/L 9. Hyperkalemia 7.1 mEq/L 10. Hyperkalemia 7.1 mEq/L 11. Hyperkalemia 7.9 mEq/L 12. Hyperkalemia 8.0 mEq/L The rhythm is dual paced. The QRS complex is normally wide in a ventricul...

EKG strips showing "tall T waves" which are often  characteristic of hyperkalemia. 1. Hyperkalemia 6.2 mEq/L 2. Hyperkalemia 6.8 mEq/L 3. Hyperkalemia 7.6 mEq/L 4. Normal Potassium 3.8 mEq/L  This is lead V3.  This patient also had left ventricular hypertrophy.   Compare this to the previous EKG strip shown above which also is taken from a V3 lead. 5. Hyperkalemia 6.8 mEq/L
