Question 7 · LEK · Potassium balance
The abnormalities in ECG which are characteristic of hyperkalemia include:
1) ST depression;
2) flattened P wave;
3) shortened QT intervals;
4) tall and narrow T waves;
5) tall and wide U waves.
The correct answer is:
2) flattened P wave;
3) shortened QT intervals;
4) tall and narrow T waves;
5) tall and wide U waves.
The correct answer is:
- A. 1,2,4,5.
- B. 1,4,5.
- C. 3,4,5.
- D. 2,3,4.
- E. 2,4.
Hint
Hyperkalaemia speeds repolarisation and depresses atrial conduction; hypokalaemia gives a largely opposite ECG pattern.
