Question

An athlete uses a potassium-rich salt substitute heavily and develops palpitations and an ECG showing peaked T waves. Which diagnosis and causative behavior is most consistent with this presentation?

Accepted Answer

Hyperkalemia caused by excessive intake of potassium from the salt substitute; peaked T waves are a classic ECG sign and intake should be stopped and potassium levels checked promptly.

Answer

A potassium-independent cardiac conduction disorder that is unrelated to dietary intake and does not require checking serum electrolytes or changing the athlete's supplement habits.

Answer

Hypokalemia from sweating during exercise; peaked T waves indicate low potassium and the athlete should drink more plain water to restore electrolyte balance.

Answer

Hypernatremia induced by the salt substitute because potassium salts always contain excess sodium leading to high sodium levels and ECG peaked T waves directly indicate sodium toxicity.
