1. A wearable defibrillation system comprising:
- a support structure configured to be worn by a patient;
a charge storage module coupled to the support structure and configured to store charge;
electrodes configured to detect an ECG of the patient;
a monitoring device other than the electrodes configured to sense a physiological parameter of the patient other than the ECG; and
a processor configured to determine at least in part from the physiological parameter whether the patient meets an unconscious bradyarrhythmia condition, andin which portions of the charge are delivered to the patient as pacing pulses if it is determined that the patient meets the unconscious bradyarrhythmia condition.

Abstract
In one embodiment, a wearable defibrillation system may sense whether its wearer meets an unconscious bradyarrhythmia condition that can be associated with becoming unconscious. Even though such a condition might not be helped with a defibrillation pulse, the wearable defibrillation system may still administer pacing pulses to prevent the bradycardia from becoming worse, such as a sudden cardiac arrest. In some embodiments, the pacing pulses are administered at a frequency too slow for the patient to regain consciousness. An advantage is that, because the patient remains unconscious, he does not experience the sometimes severe discomfort due to the pacing pulses.

19. A non-transitory computer-readable storage medium storing one or more programs which, when executed by a wearable defibrillation system worn by a patient, they result in:
-
causing to be sensed a physiological parameter of the patient other than the patient'"'"'s ECG; causing to be determined at least in part from the physiological parameter whether the patient meets an unconscious bradyarrhythmia condition; and if so, causing to be delivered pacing pulses to the patient.
