GROUPING SIMILAR EPISODES DETECTED BY A WEARABLE MEDICAL DEVICE (WMD)
Technologies and implementations related to facilitating grouping of electrocardiogram (ECG) signals of a heart of a person (e.g., patient) wearing a wearable medical device (WMD). The ECG signals may be acquired during various times (e.g., during a normal rhythm of the heart and/or during an event of the rhythm of the heart) including various times of activity of the person (e.g., sleeping, awake, active, inactive, etc.). The ECG signals may be received and analyzed to determine if the ECG signals may be indicative of an event associated with a heart of the person or not.
