A Method to Differentiate between Ventricular Fibrillation and Asystole during Chest Compressions Using Artifact-Corrupted ECG Alone

Early defibrillation in conjunction with chest compression (CC) is crucial for the return of spontaneous circulation (ROSC) in patients suffering from cardiac arrest [1,2]. The current application of an automated external defibrillator (AED) requires CCs to be interrupted during automatic rhythm analysis, as the mechanical activity from the CCs introduces artifact components into the electrocardiogram (ECG) signal and causes inaccuracy of the shock/nonshock decision of the AED [3]. However, the interruption of CCs compromises circulation and further adversely affects the ROSC probability [4 –6].
