Impact of electric current to the heart (electrical stimulation) is used to bring the heart rhythm back to normal and to restore the heart when it stops. To save a man who urgently needs to normalize the heartbeat. Comes to the aid pacemaker. At a certain frequency, duration and amplitude of electrical pulses used as an artificial stimulus, the excitation of nerve and muscle tissue of the heart.
It is interesting to note that the physicians of ancient Rome used to treat certain diseases of electroshock therapy, exposing their patients the action of an electric discharge chute.
And what if violated path conducting excitation from the atria to the ventricles, or changes in heart rate is so severe that the patient's life threatened? In such cases, the stimulation should be continuous.
To harmonize with the rhythm of ventricular fibrillation can be used to reduce the "electronic bridge" consisting of two pairs of electrodes - and a miniature amplifier. "E-Bridge" by providing a bio-stimulator, is both bioelectric control devices as a control signal generated by the heart, not from outside the unit.
Developed several types of automatic pacemaker, representing an electronic generator that is implanted in the patient's chest. Such a stimulant, giving the heart a certain rhythm of work, essentially an electronic prosthesis that performs the function of the pacemaker. The generator produces pulses of about 2 m \ s with a pulse repetition rate of 50-80 per minute. Stimulator implanted under the skin, and the wires from it, covered with special insulation of silicone rubber, is supplied to the heart.
