Hypokalemia and Hypercalcemia ECG
Hypokalemia and Hypercalcemia ECG
  • The slow sinus P waves are conducted with a Prolonged PR Interval (can be caused by hypokalemia)
  • There is Left Axis Deviation and probably LBBB (although V6 doesn’t look like LBBB)
  • Q waves in V1 – V4 and slow R wave progression (could indicate old anterior MI)
  • Prominent U waves in V2 – V5 (seen in hypokalemia)
  • Shot QT Interval best seen in lateral and inferior leads (seen in hypercalcemia)
