Abstract
A medical device capable of analyzing a patient's ECG, such as an external defibrillator, may be operated according to a method including the steps of: (a) determining if the patient is undergoing motion; (b) if it is determined that the patient is undergoing motion, providing an indication of patient motion; (c) after providing the indication, determining if the patient is undergoing motion, and if the patient is undergoing motion, starting ECG analysis after an elapsed time T.sub.0. The elapsed time T.sub.0 may be measured from a point in time prior to the commencement of step (a). The method may further include the steps of collecting ECG data of the patient, and initiating analysis of the ECG data prior to step (b). The step (b) may further include the step of interrupting the prior initiated ECG analysis. The method may further include the step of starting a timer when the ECG analysis is commenced, to measure elapsed time.
