  • Apparatus and method for energy management in atrial defibrillator
    Publication number: 20050027318
    Abstract: An apparatus and method for delivering electrical shock therapy in order to treat atrial tachyarrhythmias such as fibrillation in which the energy stored in a capacitor used to deliver a shock pulse is monitored and adjusted. A charging circuit is used to charge the capacitor from a supply voltage upon detection of an atrial arrhythmia, and a controller monitors sensed ventricular depolarizations until R-wave synchrony requirements are met so that an atrial shock pulse can be safely delivered. The controller also attempts to maintain the voltage of the capacitor at a specified voltage before delivery of the shock pulse by operation of the charging circuit.
    Type: Application

  • Method and apparatus for cardiac shock therapy
    Publication number: 20040111123
    Abstract: An apparatus and method for delivering defibrillation shock therapy employing a multi-terminal pulse output circuit. In such a circuit, at least three electrode lead terminals are switchably connected to the positive and negative terminals of an energy storage capacitor. By serially switching selected electrode lead terminals to the capacitor terminals, a variety of shock pulse waveforms may be generated.
