Milk-alkali syndrome electrocardiogram
Introduction
Overview
Overview
Milk-alkali syndrome causes hypercalcemia and hypercalcemia may cause the following findings on electrocardiogram (ECG): shortened QT interval (the most common finding), shortened ST segment, PR prolongation, increased amplitude of QRS complex, decreased amplitude of T wave, T wave notching, transient ST segment elevation, bradycardia, sinus arrest, and ventricular arrhythmias.
Electrocardiogram
Electrocardiogram
Milk-alkali syndrome causes hypercalcemia and hypercalcemia may cause the following findings on electrocardiogram (ECG):[1][2][3][4][5][6]
- Shortened QT interval (the most common finding)
- Shortened ST segment
- PR prolongation
- Increased amplitude of QRS complex
- Decreased amplitude of T wave
- T wave notching
- Elevation of J point
- Transient ST segment elevation
- Osborn wave
- Bradycardia, sinus arrest, and premature ectopic beats
- Ventricular arrhythmias
- ECG findings in severe hypercalcemia may mimic myocardial infarction.
