title: [Value and methodology of electric stimulation in intracardiac examination of patients with ventricular pre-excitation syndrome].
abstract: The procedures involved in different techniques of cardiac electrostimulation for the diagnosis of the pre-excitement syndrome were examined in 154 patients. In a group of 150 patients with provoked (140) or spontaneous (10) tachycardia developing in response to endocardial electrocartography, the paroxysmal supraventricular tachycardia was noted in 95.5%, atrial flutter in 11.4%, atrial flutter-fibrillation in 5.7%, atrial fibrillation in 29.8%, A-V tachycardia in 3.7%. The methods of diagnostic cardiac electrostimulation are of great importance in determining the type, localization, electrophysiologic properties and mechanisms of heart rhythm disorders and in selecting a rational therapeutic method.
