WEARABLE CARDIOVERTER DEFIBRILLATOR (WCD) SYSTEM REACTING TO HIGH-AMPLITUDE ECG NOISE

摘要

To provide wearable cardioverter defibrillator (WCD) systems, storage media that may store programs, and methods.SOLUTION: The WCD system analyzes an ECG signal of a patient to determine whether or not the patient should be given an electric shock to restart his or her heart. If so, then the WCD system first gives a preliminary alarm to the patient, asking him or her to prove he or she is alive if he or she is. The WCD system further determines whether the ECG signal contains too much high amplitude (H-A) noise, which can distort the analysis of the ECG signal. If too much H-A noise is detected for a long time, the WCD system may eventually alert the patient about their activity, so that the ECG noise may be abated. The WCD system may even pause the analysis of the ECG signal, so that there will be no preliminary alarms that could be false until the ECG noise is abated.SELECTED DRAWING: Figure 1
