1. An external defibrillator, comprising:
- circuitry for delivering a defibrillation pulse to defibrillation electrodes applied to the chest of a patient;
circuitry for monitoring a pulse signal from the patient, wherein the circuitry comprises circuitry for receiving the pulse signal from a piezoelectric sensor configured to detect motion caused by blood moving through an artery of the patient;
circuitry for monitoring an ECG signal from the patient;
one or more processors configured to determine whether it is appropriate to deliver a defibrillation shock to the patient, the determination being based at least in part on the content of the ECG signal and on the content of the pulse signal.

Abstract
A method of operating an automated external defibrillator, the method being implemented by circuitry and one or more processors of the defibrillator, comprising monitoring a pulse signal from the patient; monitoring an ECG signal from the patient; determining whether it is appropriate to deliver a defibrillation shock to the patient, the determination being based at least in part on the content of the ECG signal and on the content of the pulse signal.
