The Frequency and Association of Dyskalemias With Types of Arrhythmias and Their Predictors in Emergency Cardiac Care Patients

Potassium derangements are common in emergency cardiac patients and significantly increase the risk of arrhythmias. Hypokalemia predisposes to ventricular arrhythmias, while hyperkalemia more often results in bradyarrhythmias and conduction blocks. Chronic kidney disease is an independent predictor of arrhythmias.
