- 1. An external defibrillator comprising:
a processor; a defibrillator pulse generator operatively connected to the processor and configured to generate a defibrillating shock; and electrode pads configured to be operatively connected to the defibrillator pulse generator and the processor to deliver the defibrillating shock from the defibrillator pulse generator to the patient, the electrode pads further configured to deliver one or more ECG signals from the patient to the processor, wherein the processor is programmed to:
analyze one or more electrocardiogram (ECG) signals from the patient during delivery of chest compressions to the patient;
determine appropriateness of delivering a shock to the patient based on the analysis of the one or more ECG signals during the delivery of chest compressions of a CPR interval;
determine that the chest compressions of the CPR interval have been completed;
analyze one or more ECG signals acquired in an absence of chest compressions within about 5 seconds after cessation of the chest compressions of the CPR interval to confirm the appropriateness of delivering the shock to the patient; and
provide an indication on a display screen of a recommendation of providing a shock to the patient based on the determined appropriateness of delivering the shock to the patient.
- 27. A method for providing electrical therapy to a patient, the method comprising:
analyzing one or more electrocardiogram (ECG) signals from the patient during delivery of chest compressions of a CPR interval to the patient; determining appropriateness of delivering a shock to the patient based on the analysis of the one or more ECG signals during the delivery of the chest compressions; determining that chest compressions of the CPR interval have been completed; after the chest compressions of the CPR interval have been completed, analyzing one or more ECG signals to confirm the appropriateness of delivering the shock to the patient within about 5 seconds after a rescuer has completed the chest compressions of the CPR interval; and providing an indication on a display device of a recommendation of providing a shock to the patient based on the determined appropriateness of delivering the shock to the patient.
