Abstract:
1. An externally wearable patient treatment device comprising: cardiac sensing electrodes connected to the device, said cardiac sensing electrodes adjacent said patient in proximity to said patient's skin; treatment elements connected to the device, said treatment elements adjacent said patient in proximity to said patient's skin; at least one patient motion detector connected to the device and generating a signal indicative of patient activity; at least one control to evaluate signals from said motion detector and said cardiac sensing electrodes to determine if said signal is indicative of patient activity appropriate for treatment; a treatment algorithm accelerating or delaying treatment based upon the output of said at least one patient motion detector; a patient response sensor which can delay treatment when operated by said patient; and a stimulator alarm providing patient stimulus after a cardiac condition is sensed and before a treatment is initiated, wherein said treatment algorithm initiates treatment when the output of said at least one patient motion detector indicates a lack of patient activity and no input is received from said patient response sensor.
