Abstract

The study included 149 patients with implanted cardioverters-defibrillators (CD) at high risk of development of ventricular tachyarrhythmia. It was found that unmotivated malfunction of CD occurs in supraventricular tachycardia, when a short episode of ventricular tachycardia spontaneously ends before CD starts to work, when T-wave is mistaken for ventricular contraction, in defective isolation, electrode dislocation. A method to reduce frequency of CD malfunction is proposed. To prevent unmotivated discharges it is recommended to use attendant drug therapy, upgrading equipment and algorithms of tachyarrhythmia detection, early correction of myocardial ischemia and electrolyte disorders.
