Abstract

Detection of ventricular fibrillation (VF) by means of appropriate algorithms is crucial for automatic external defibrillators. One of the more recent and effective techniques reported in scientific literature is the phase space reconstruction (PSR), which is based in the non-linear and chaotic behavior of the electrocardiogram. We propose in this work a PSR based algorithm for VF detection considering variable delay times which stresses the differences between normal signals and irregular signals of VF. The evaluation of the algorithm was made with all records of the MIT-BIH and CU databases without any pre-selection. The results have shown improvement in terms of sensitivity, specificity, positive predictivity and accuracy in respect to other algorithms evaluated under similar conditions.
