Pseudo P pulmonale is seen in:
Pseudo P pulmonale is seen in:
Show Hint
Tall peaked P waves mimicking P pulmonale from a low electrolyte.

- Hypokalemia
- Hyponatremia
- Hypocalcemia
- Hypercalcemia
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Separate the real P-wave abnormalities from the pseudo pattern. True P pulmonale means right atrial enlargement with tall peaked P waves.
Step 2: When the ECG shows tall peaked P waves that look like P pulmonale but the right atrium is in fact normal, the finding is labelled pseudo P pulmonale, an electrolyte-driven mimic rather than a structural change.
Step 3: The electrolyte disturbance classically responsible is low serum potassium, so among the options the answer is hypokalemia.
\[\boxed{\text{Hypokalemia}}\]
