[The use of multiprogrammable cardiac electrostimulators for treating brady- and tachyarrhythmias in patients with ischemic heart disease].

Examined were 54 patients with different disorders of the cardiac rhythm with an implanted programmed electrocardiostimulator (ECS-200). The authors worked out methods and criteria of choosing individual regimes of electrostimulation, evaluated their effect on the severity of stenocardia and grade of circulatory insufficiency. The threshold frequency of stenocardia is of major significance in determining the optimal frequency of electrostimulation for patients with stable atrioventricular block. For patients with sinus node weakness and transitory atrioventricular blocks the criteria of choice of electrostimulation parameters is maximum maintenance of the sinus node rhythm with a frequency of not less 50/min.
