Abstract
A defibrillator for atrium and/or ventricle having at least two capacitors which in the production of defibrillation pulses are discharged in at least two phases in succession in different configurations, wherein there are provided switching means which control the discharge in the at least two discharge phases in such a way that the mean value of their voltages is substantially equal and no voltages below the rheobase occur in any of the discharge phases, and a corresponding defibrillation method.
Claims22
A device for defibrillating an atrium and/or a ventricle, said device having at least two capacitors which in the production of defibrillation pulses are discharged in a first phase involving a first configuration and in a successive second phase involving a different second configuration, wherein the device further has a means for switching that controls the discharge in the discharge phases of the first and second configurations so that the mean values of the voltages are substantially equal during the pulse durations for the first and second configurations and voltages below the rheobase do not occur in any of the discharge phases.
A method for defibrillating an atrium and/or a ventricle with a device having at least two capacitors, the method characterized by the steps of first discharging the capacitors in a first phase involving a first configuration and then discharging the capacitors in a second phase involving a different second configuration, wherein the discharge in the at least two discharge phases is controlled in such a way that the mean value of the voltages in the discharge phases is substantially equal and does not fall below the rheobase in any of the discharge phases.
