1. A wearable medical device comprising:
- a plurality of sensing electrodes to sense an electrocardiogram signal of a patient;
a plurality of therapy electrodes to provide treatment to the patient;
a garment to be worn about a torso of the patient and receive the plurality of sensing electrodes and the plurality of therapy electrodes;
a motion detector;
a processor coupled to the plurality of sensing electrodes, the plurality of therapy electrodes, and the motion detector; and
a memory communicatively coupled to the processor and comprising instructions that when executed by the processor cause the processor to;
receive movement information comprising at least acceleration information and heading information from the motion detector;
detect a movement of the wearable medical device from the movement information received from the motion detector, wherein the movement of the wearable medical device comprises a distance traveled by the wearable medical device and a direction traveled by the wearable medical device; and
estimate a current location of the wearable medical device relative to a previous location of the wearable medical device using dead reckoning based at least in part on the distance traveled by the wearable medical device and the direction traveled by the wearable medical device.
