ABSTRACT:
A system and method for detecting ventricular fibrillation based on chaos theory. A Poincare plot of the amplitude of the ECG signal is generated and used to detect the presence of fibrillation. The plot is monitored for the data points drifting off the plot axes. Upon detecting such drift, the presence of ventricular fibrillation is confirmed. The system and method may be used as a primary detection scheme or as a backup system to reconfirm fibrillation detection using conventional techniques.
