An external defibrillator includes a detector used to detect a life threatening condition of a patient, a controller operating the defibrillator automatically and a therapy delivery circuit that delivers appropriate therapy. Advantageously a parameter is derived from the cardiac signals sensed in the patient, the parameters being used to differentiate between shockable events such as ventricular tachyarrhythmia and other events such as SVT. The defibrillator is attached to a patient by an attendant and once it is attached, the defibrillator is adapted to monitor the patient and when a life threatening condition is detected, to apply therapy automatically, i.e., without any involvement by the patient or the attendant. |
