[Treatment of paroxysmal ventricular tachycardia]

The authors present a retrospective evaluation of the risk stratification and therapy of 53 patients with ventricular tachycardia. They present the diagnostical algorithm used for the detection of risk of sudden death. The most frequently used drug in the set of patients was amiodarone in monotherapy or in combination with other drugs. Sotalol was used for both, its antiarrhythmic nature, and for its ability to reduce the defibrillation threshold in patients with an implanted automatic implantable cardiovertor-defibrillator (AICD). Antiarrhythmic drugs of class I in monotherapy were used in patients with non-coronary causes of ventricular tachycardia and with normal left ventricular function. The authors, on the basis of sudden death of three patients with low ejection fraction of the left ventricle which were recorded even despite Holter apparatus and electophysiologically confirmed supression of ventricular tachycardia, recommend to consider in this group of patients the primary AICD implantation.
