Wearable cardioverter defibrillator (wcd) system reacting to high-amplitude ecg noise

This invention describes a wearable defibrillator that monitors a patient's heart rhythm and can deliver an electric shock if needed. A key feature is its ability to detect when the heart signal is too noisy due to patient movement or other interference. If excessive noise is detected, the device will delay any potential shock or alarm until the noise subsides or a set time passes, preventing false alarms.

Why it matters: Recent advancements in machine learning for signal processing have significantly improved the ability to accurately identify and filter high-amplitude noise from ECG readings. This could make the WCD's noise detection and delay mechanism more precise and reliable than when it was filed.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedECG sensing, high-voltage discharge, safety-critical software
