Improved Cardiac Arrhythmia Prediction Based on Heart Rate Variability Analysis
This work addresses the challenge of effective arrhythmia management for patients at high risk of sudden cardiac death, though it appears incremental as it builds on existing HRV analysis methods.
The paper tackled the problem of early detection of dangerous cardiac arrhythmias like ventricular tachycardia and atrial fibrillation to prevent sudden cardiac death, proposing novel methods based on Heart Rate Variability (HRV) analysis that showed good performance and potential for deployment in resource-constrained devices such as pacemakers and defibrillators.
Many types of ventricular and atrial cardiac arrhythmias have been discovered in clinical practice in the past 100 years, and these arrhythmias are a major contributor to sudden cardiac death. Ventricular tachycardia, ventricular fibrillation, and paroxysmal atrial fibrillation are the most commonly-occurring and dangerous arrhythmias, therefore early detection is crucial to prevent any further complications and reduce fatalities. Implantable devices such as pacemakers are commonly used in patients at high risk of sudden cardiac death. While great advances have been made in medical technology, there remain significant challenges in effective management of common arrhythmias. This thesis proposes novel arrhythmia detection and prediction methods to differentiate cardiac arrhythmias from non-life-threatening cardiac events, to increase the likelihood of detecting events that may lead to mortality, as well as reduce the incidence of unnecessary therapeutic intervention. The methods are based on detailed analysis of Heart Rate Variability (HRV) information. The results of the work show good performance of the proposed methods and support the potential for their deployment in resource-constrained devices for ventricular and atrial arrhythmia prediction, such as implantable pacemakers and defibrillators.
