A method for stimulating the cardiac action by means of an electrocardiostimulator implanted in the patient's body and connected to the heart, ensuring a desired heart rate, whereby a packet of electric pulses is produced, the number of heart contractions being equal to the number of pulse packets applied to the heart in the presence of stimulating actions. The implantable electrocardiostimulator comprises a main pulse generator connected to a power source and associated with the heart through electrodes, as well as an auxiliary pulse generator connected between said main pulse generator and electrodes. The natural frequency of pulses produced by said auxiliary generator is higher than the repetition frequency of pulses produced by the main generator.

Method for stimulating cardiac action by means of implanted

The present invention relates to the field of electrical engineering and more particularly to a method of D.C. voltage regulation across a load and to a device to carry this method into effect. In a method of regulating D.C. voltage across a load with the aid of a plurality of transistor inverter circuits controlled by square-wave voltage and having transformer outputs, comprising at least one main transistor inverter circuit and a number of additional transistor inverter circuits, whereby the output voltages of said transistor circuits are summed with subsequent detection, in accordance with the invention, the sum component corresponding to the main transistor inverter circuit does not reverse its sign in the course of regulation, while the sign of the component corresponding to any one of the additional transistor inverter circuits is reversed following the reversal of the sign of the difference between the total value of quantities proportional to the output voltages of the main transistor inverter circuit and several other additional transistor inverter circuits, and the value proportional to the reference voltage determining voltage across the load, by alternating a train of alternate conduction and cut-off control signals, and a train of only cut-off control signals applied to the control junction of the transistors of any one said additional transistor inverter circuit.
