1. A method of operating an external defibrillator configured to provide a defibrillation shock to a patient comprising:
- gathering physiological data;
analyzing the physiological data using a first algorithm to determine whether to initiate a shock; and
if it is determined that the defibrillation shock should be provided, analyzing the physiological data using a second algorithm to verify the determination to shock.

Abstract
In a method of operating an external defibrillator configured to provide a defibrillation shock to a patient, physiological data is gathered from the patient. Next, the physiological data is analyzed using a first algorithm to determine whether to initiate a shock. Then, if it is determined that a defibrillation shock should be provided, the physiological data is analyzed using a second algorithm to verify the determination to shock.

8. An external defibrillator comprising:
-
an electrode configured to gather physiological data from a patient;
a processor coupled to the electrode, the processor configured to;
(i) generate a sinusoidal waveform model of the physiological data;
(ii) determine a feature from the model; and
(iii) compare the feature to a standard to determine whether a shock is needed. - View Dependent Claims (9, 10, 11, 12, 13)
