Cardiac electrostimulation was conducted in 19 patients to prevent and control paroxysmal ventricular tachycardia. In 8 of those, an attempt was made to prevent tachycardia by continuous endocardial ventricular stimulation in the demand regimen. In 11 patients, a radio-frequency stimulator was implanted, its electrode positioned in the right ventricle to control current tachycardiac attacks. A 3-5-second stimulation at frequencies of 180-220 impulses per minute was sufficient to control the attack in 8 of the patients, while programmed ventricular stimulation only was needed to produce the effect in 3 patients. |
