  • Patent number: 8401637
    Abstract: A method and system for treating an individual experiencing cardiac arrest using an automatic external defibrillator (AED) includes placing a first and a second electrode of the AED in electrical communication with an exterior surface of the individual. A need to apply a high voltage defibrillation signal to the individual is automatically determined. The method also includes automatically causing the AED to apply a medium voltage therapy (MVT) signal through the first and the second electrodes to the individual. The MVT signal is applied to induce a hemodynamic effect in the individual. Alternatively, or additionally, the MVT signal is applied to induce a respiratory effect in the individual. Optionally, the MVT signal is applied before determining the need to apply the defibrillation signal.

  • Patent number: 7706864
    Abstract: An electrical method and apparatus for stimulating cardiac cells causing contraction to force hemodynamic output during fibrillation, hemodynamically compromising tachycardia, or asystole. Forcing fields are applied to the heart to give cardiac output on an emergency basis until the arrhythmia ceases or other intervention takes place. The device is used as a stand alone external or internal device, or as a backup to an ICD, atrial defibrillator, or an anti-tachycardia pacemaker. The method and apparatus maintain some cardiac output and not necessarily defibrillation.
