  • Enhanced rhythm identification in compression corrupted ECG
    Patent number: 7567837
    Abstract: A method is provided for analyzing the condition of a patient to determine whether or not a defibrillation shock should be applied, without stopping CPR (primarily chest compressions). While chest compressions continue to be applied to the victim, the system differentiates between (1) a perfusing rhythm that has the capability of leading to a beating heart without a shock and (2) ventricular fibrillation (VF) which sometimes occurs in the presence of ventricular tachycardia (VT), in which there is no capability for leading to a beating heart without a shock. Defibrillation shocks should be applied only when needed and that is in the presence of VF and sometimes in the presence of VT.
