[Electrocardiostimulation in the treatment of recurrent ventricular fibrillation in a patient with long QT syndrome on the ECG].

Electrical stimulation of the ventricles with frequency more than spontaneous heart rate was used in a 36-year old patient suffering from rheumatic fever, paroxysms of ciliary arrhythmia to prevent recurring ventricular fibrillation in the presence of a QT elongated interval on the ECG. Medicinal therapy was provided in parallel. She was discharged in a satisfactory condition. For 11 mos. of outpatient treatment there were no fits of loss of consciousness; the QT interval was not elongated. It is concluded that electrocardiostimulation is effective for the prevention of ventricular fibrillation in patients with the syndrome of a QT elongated interval on the ECG.
