Algorithm for detection of ventricular fibrillation on line in a CCU

Abstract

A new simple and fast algorithm for VFIB (ventricular fibrillation) detection has been developed and tested in an AHA (American Heart Association) database. The algorithm is based on the portions of small and high derivatives in the ECG (electrocardiographic) signal. The performance is found to be adequate while showing detection for all VFIB episodes in the AHA database within 14 s, on average. All the false positives were found to be VTAC (ventricular tachycardia) episodes, which usually precede the VFIB.<>
