FIELD: medicine.
SUBSTANCE: invention refers to medical equipment. An external defibrillator for two-phase defibrillation waveform supply comprises a high-voltage circuit, which accommodates a condenser, as well as a pair of electrodes and a number of switches. The high-voltage circuit is presented to charge the condenser to supply the defibrillation pulse. The switches comprise an H-bridge, connected between the condenser and electrodes and can be connected to first and second phases of the two-phase defibrillation waveform to the electrodes. A second-phase tilt is adjustable. The controlled conduction path comprises the H-bridge switch and enables the controlled conduction path for the second phase of the two-phase waveform.
EFFECT: using the invention enables higher safety and effectiveness of defibrillation.
