Which electrolyte abnormality is listed as a contributing factor to symptoms?

Potassium is the electrolyte whose abnormal levels most directly change how nerves and muscles behave, and it has a strong, immediate impact on heart rhythm. Small shifts in potassium alter the resting membrane potential and how easily cells fire, which translates into symptoms like muscle weakness, fatigue, cramps, palpitations, or arrhythmias. Because of this direct influence on neuromuscular and cardiac function, potassium disturbances are a common contributing factor to a patient’s symptoms in many clinical notes. Sodium affects fluid balance and neuronal activity, calcium governs muscle contraction and some cardiac conduction, and chloride participates in acid-base balance, but none of them have as immediate and dramatic an effect on excitability and rhythm as potassium in typical symptom clusters.
