Question

Tall T-wave in ECG indicates

• A. Hyperkalemia
• B. Hypokalemia
• C. Myocardial infarction
• D. Tachycardia

Hint:

ECG changes with K\textsuperscript{+}: Hyperkalemia → peaked T; Hypokalemia → flattened T / U-wave.

Answer 1

The Correct Option is A

• Tall, peaked T-waves on ECG are a classic sign of hyperkalemia (elevated serum potassium).
• Hypokalemia produces flattened or inverted T-waves and U-waves.
• Therefore the correct answer is (1) Hyperkalemia.
