1. A patient-specific defibrillator system, comprising:
a support structure;
one or more sensors;
an energy storage device to store electrical charge;
one or more therapy electrodes; and
a processor coupled to the one or more sensors, the energy storage device, and the one or more therapy electrodes, wherein the processor is configured to:
use an algorithm to analyze information derived from signals output by the one or more sensors, the algorithm being used to determine a need for therapy by the patient-specific defibrillator system,
wherein the processor is further configured to dynamically calculate and re-calculate coefficients of the algorithm using an artificial intelligence analysis performed on data collected from multiple different persons, and
wherein the algorithm is derived, at least in part, from the artificial intelligence analysis performed on data collected from a patient using the one or more sensors; and
based on the determination of the need for therapy by the patient-specific defibrillator system, cause at least some or all of the electrical charge stored in the energy storage device to be discharged through the one or more therapy electrodes while the support structure is being worn.
