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.
