Overview
The EKG shows a prolonged QT interval.
Electrocardiogram
ECG changes are non-specific and include:
- A slight prolongation of conduction and the depression of the ST segment
- Magnesium depletion increases susceptibility to arrhythmogenic effects of drugs such as isoproterenol and cardiac glycosides and this includes:
- Supraventricular and ventricular arrhythmias
- Torsade de pointes (repetitive polymorphous ventricular tachycardia with prolongation of QT interval) has been reported in cases of hypomagnesaemia
- Torsade de pointes and other arrhythmias have been successfully treated with magnesium. However, this may be a pharmacological effect, independent of underlying magnesium deficiency.
