[Use of P-synchronized electrical stimulation of the heart for preventing supraventricular tachycardia paroxysms due to accessory conduction pathways].
The paper deals with a possibility to apply P-synchronized ventricular stimulation for the prevention of frequent, drugirresponsive paroxysms of supraventricular tachycardia (SVTC) due to the accessory conduction pathways. During the electrophysiologic study of 5 patients with SVTC paroxysms, the presence of Kent's bundle conducting the impulses in a retrograde way has been revealed. The observed mechanisms of SVTC occurrence (delayed His-Purkinye system conduction in 2 patients and atrioventricular nodal conduction in 3 patients) enabled its prevention to be achieved by a method of ventricular electric stimulation in the P-synchronized regimen with a shortened atrioventricular delay in the impulse conduction. While performing this type of stimulation tachycardia episodes were completely terminated, and it was impossible to provoke them by different types of stimulation.
