ECG Changes

Mirtazapine, a medication primarily used to treat depression, anxiety, and other mental health conditions, has been associated with certain changes in the electrocardiogram (ECG) readings. ECG changes can include alterations in the intervals that measure the time taken for electrical signals to pass through the heart. These changes may manifest as prolongation of the QT interval, which can increase the risk of a serious heart rhythm disorder known as Torsades de Pointes.

It is important for patients taking Mirtazapine to be aware of these potential ECG changes and to discuss any concerns with their healthcare provider. Regular monitoring of ECG readings may be necessary to ensure that the medication is being well-tolerated and that any adverse effects are identified promptly.
