Practice EKG Rhythm Strips 143: Various Hyperkalemia

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 ventricular paced rhythm.  However, the underlying hyperkalemia causes ever greater widening of the QRS complex.


12.
Hyperkalemia 8.9 mEq/L







The PR interval is prolonged.  There are ventricular pacer spikes before the QRS complex which would normally be wide.  However, the underlying hyperkalemia causes ever greater widening of the QRS complex with elevation of the T waves.

13.
Hyperkalemia 10.2 mEq/L










The rhythm has nearly a sine wave configuration.
