Abstract

A wearable defibrillator for monitoring life threatening arrhythmias in a patient includes a plurality of electrocardiogram (ECG) sensing electrodes to generate ECG data, one or more audio devices, and one or more processors. The one or more audio devices include a microphone configured to detect background noise and a speaker configured to produce an audio output. The one or more processors are configured to detect. from at least the ECG data, whether the patient is experiencing a life threatening arrhythmia, cause an audible alarm to be produced as the audio output in response to detecting that the patient is experiencing the life threatening arrhythmia, identify a level of the background noise detected by the microphone in response to detecting that the patient is experiencing the arrhythmia, and increase a confidence that the detected arrhythmia is appropriate for treatment in response to identifying that little to no background noise is detected.
