A method comprising: at a training stage, training a machine learning algorithm on a training set comprising: (i) Heart Rate Variability (HRV) parameters extracted from temporal beat activity samples, wherein at least some of said samples include a representation of a Ventricular Fibrillation (VF) event, (ii) labels associated with one of: a first period of time immediately preceding a VF event in a temporal beat activity sample, a second period of time immediately preceding the first period of time in a temporal beat activity sample, and all other periods of time in a temporal beat activity sample; at an inference stage, receiving, as input, a target HRV parameters representing temporal beat activity in a subject; and applying said machine learning algorithm to said target HRV parameters, to predict an onset time of a VF event in said subject.

Predicting ventricular fibrillation

A method comprising: receiving a plurality of data segments each representing human cardiac activity; calculating, from each of said data segments, a first value representing a distribution of a heart rate variability (HRV) parameter; acquiring a signal representing cardiac activity in a patient; deriving a second value representing distribution of an HRV parameter in said signal; and indicating an atrial fibrillation (AF) event in said patient, when a difference between said first and second values is above a predetermined threshold.
