Premature Atrial Contractions and Electrolyte Imbalances
Premature atrial contractions are associated with electrolyte abnormalities, with hypokalemia (low serum potassium) being the most commonly cited electrolyte disturbance. [1][2]
Electrolyte Imbalance Most Commonly Implicated
- Hypokalemia (low potassium) is a commonly recognized electrolyte cause of premature contractions and atrial ectopy. [1][2]
Related Electrolyte Abnormalities
- Hypomagnesemia (low magnesium) is also associated with cardiac arrhythmias and can contribute to supraventricular ectopy in clinical contexts where electrolyte disturbances coexist. [3]
Clinical Implication
- Serum electrolyte testing is used to identify and correct electrolyte abnormalities contributing to premature atrial contractions. [1][4]
