摘要：
A system includes an ambulatory medical device and a server. The ambulatory medical device comprises: a digital signal processing module configured to: detect an abnormal rhythm from an electrocardiogram (ECG) signal of a patient using a first signal processing routine； and generate a first flag indicating an abnormal rhythm is detected； and a noise detector module configured to: receive the ECG signal from the digital signal processing module； execute a second signal processing routine to classify the abnormal rhythm as one of an arrhythmia event and a noise event； and, if the abnormal rhythm is classified as a noise event, initiate a preconfirmation period during which the noise detector module continues to evaluate the abnormal rhythm and classify the abnormal rhythm as one of an arrhythmia event and a noise event using the second signal processing routine； and generate a second flag indicating the start of the preconfirmation period； and a server configured to: receive the ECG signal, the first flag indicating the abnormal rhythm, and the second flag indicating the start of the preconfirmation period； and provide a visual indication of the preconfirmation period.
