“…We show that one can predict ventricular tachyarrhythmia with moderate accuracy using modern machine learning algorithms and a combination of features from HRV signals in time, frequency, and nonlinear domains in the same group of patients with heart failure. While there has been research on the prediction of SCD using HRV signals,[1318] most of these previous studies use HRV signals from healthy subjects as the baseline to predict SCDs in patients with heart disease. Also, while there is a previous study on the prediction of ventricular tachycardia using pre-ventricular-arrhythmic rhythms and control rhythms from the same group of patients, the sample has 41 subjects and 104 recordings.…”

“…[12] In particular, HRV signals have been used with machine learning to predict the occurrences of sudden cardiac death (SCD) in the past. [1318] However, most of these studies compared pre-ventricular-tachyarrhythmia signals from human subjects at risk of SCD with HRV signals from healthy human subjects. While those findings show that there are significant differences between pre-ventricular-arrhythmia HRV signals from patients with heart disease and HRV signals from healthy subjects, we cannot conclude how practical it is to predict ventricular tachyarrhythmia in patients who received ICDs.…”

“…Therefore, electrical measurements of the heart, in the form of ECG signals, can provide a holistic assessment of health [103]. However, a fundamental problem with such general indicators of health is the complexity of interpretation.…”

“…Their results presented accuracy of 83.96% for the fourth 1 min before SCD onset. Rajendra et al [48] proposed a method using discrete wavelet transform and nonlinear analysis of ECG signals. They segmented the ECG signal 4 min before SCD occurrence.…”
