Key result
A hybrid prediction index based on ECG phase-portraits predicted impending ventricular arrhythmia 356 beats before onset on average, with 96.88% sensitivity and 100% specificity.
Why the study?

May enable preemptive monitoring in high-risk patients; hypothesis-generating and requires prospective validation before clinical use.
Does a hybrid prediction index using ECG phase-space diagrams predict impending ventricular arrhythmia in VA patients?
A novel hybrid statistical index using ECG phase-space reconstruction can accurately predict impending ventricular arrhythmias hundreds of beats before onset.
A 2014 study studied Ventricular arrhythmia (n=32). Hybrid prediction index from ECG phase-portraits was evaluated on Prediction of impending ventricular arrhythmia. A hybrid prediction index based on ECG phase-portraits predicted impending ventricular arrhythmia 356 beats before onset on average, with 96.88% sensitivity and 100% specificity.
