[Ventricular arrhythmia in hypertrophic cardiomyopathy. When and how to treat].
Patients with apical hypertrophy have a natural favourable history. Non Specific Ventricular Tachycardia (NSVT) at ambulatory monitoring is more favourable if it is not associated with consciousness disorders. A high rate of NSVT episodes at Holter or the association with syncope can lead to a less favourable prognosis and therefore require pharmacological or electric treatment. The role of ET (electrophysiological test) has not yet been clearly described and is in progress. Recent studies of molecular genetics help to identify high-risk patients. Sustained monomorphic VT is not frequent but when it occurs it should be treated with BT. Patients with a light risk of VT should be treated with pharmacological therapy (white amiodarone and/or sotalol) and preferably with implantable defibrillator (ID) if VT cannot be eliminated. ID should be implanted also in the few patients surviving heart attack to avoid the risk of relapses.
