Supports urgent ECG-guided management of severe dyskalemia; leaves open prospective validation of thresholds in modern cohorts.
Prompt recognition and treatment of potassium abnormalities, particularly using ECG for diagnosis, is critical to prevent life-threatening cardiac arrhythmias.
Allan B. Schwartz (1978) conducted a review in Potassium-related cardiac arrhythmias. Severe potassium abnormalities are medical emergencies, with clinical problems occurring at potassium levels <2.7 mEq/liter and life-threatening hyperkalemia at levels >7.0 mEq/liter.
