Systems and methods for detecting health disorders

An external wearable medical device comprising:

• a memory;
• a plurality of electrocardiogram (ECG) sensors configured to be disposed on a patient;
• at least one motion sensor configured to be disposed on the patient;
• at least one processor coupled to the memory;
• and
• an event manager executed by the at least one processor and configured to:
• monitor an ECG signal of the patient received from at least one of the plurality of ECG sensors;
• receive patient activity data from the at least one motion sensor;
• detect, based on the patient activity data, data indicative of a syncope precursor event as a sign of an impending syncope, the data indicative of the syncope precursor event being data related to at least one of a change in the patient's gait and increased swaying when the patient walks;
• and
• store, in the memory of the external wearable medical device, the ECG signal of the patient during the syncope precursor event in association with information descriptive of the timing of an occurrence of the syncope precursor event and the data indicative of the syncope precursor event.

A method of monitoring a patient, the method comprising:

• monitoring, by an external wearable medical device worn by the patient, an electrocardiogram (ECG) signal of the patient received from at least one of a plurality of ECG sensors disposed on the patient;
• receiving, by the external wearable medical device, patient activity data from at least one motion sensor disposed on the patient;
• detecting, by the external wearable medical device and based on the patient activity data, data indicative of a syncope precursor event as a sign of an impending syncope, the data indicative of the syncope precursor event being data related to at least one of a change in the patient's gait and increased swaying when the patient walks;
• and
• storing, in a memory of the external wearable medical device, the ECG signal of the patient during the syncope precursor event in association with information descriptive of the timing of an occurrence of the syncope precursor event and the data indicative of the syncope precursor event.
