Ventricular arrhythmias can be divided into two sub-types: those termed “idiopathic”, that usually appear in younger patients, and those associated to structural heart disease such as previous myocardial infarction. These arrhythmias are more dangerous and must be carefully assessed in specialized units to decide the best treatment option.
Catheter ablation is the treatment of choice for idiopathic ventricular arrhythmias given the good outcomes following the procedure. Management of ventricular arrhythmias associated with heart disease must be individualized, since pharmacological treatment, invasive treatment with catheter ablation, implantation of an automatic defibrillator or a combination of these may be necessary.
