May enable real-time VF/VT detection from brief ECGs; hypothesis-generating and requires prospective clinical validation.
A novel complexity-based sequential hypothesis testing algorithm demonstrates potential for real-time detection of lethal ventricular arrhythmias and can be implemented on hardware.
Szi-Wen Chen (2006) studied Ventricular fibrillation and ventricular tachycardia (n=70). Complexity-measure-based sequential hypothesis testing (CM-SHT) algorithm was evaluated on Overall predictive accuracy for VF and VT detection. The complexity-measure-based sequential hypothesis testing algorithm achieved an overall predictive accuracy of 96.67% for the real-time detection of ventricular fibrillation and ventricular tachycardia.
