Mechanisms of Defibrillation [PDF]
Annual Review of Biomedical Engineering, 2010 Electrical shock has been the one effective treatment for ventricular fibrillation for several decades. With the advancement of electrical and optical mapping techniques, histology, and computer modeling, the mechanisms responsible for defibrillation are now coming to light.

Defibrillation Testing During Defibrillator Implantation [PDF]
Arrhythmia & Electrophysiology Review, 2012 Implantable cardioverter defibrillators (ICDs) terminate ventricular tachycardia (VT) and ventricular fibrillation (VF) with high efficacy. ICDs improve mortality in patients after survived sudden cardiac death (SCD) and in patients at high risk of dying suddenly.

Hybrid Cathode Lithium Battery Discharge Simulation for Implantable Cardioverter Defibrillators Using a Coupled Electro-Thermal Dynamic Model [PDF]
arXiv, 2023 This paper investigates the impact of implantable cardioverter defibrillator (ICD)'s load on its lithium battery power sources through a coupled electro-thermal dynamic model simulation. ICDs are one of the effective treatments available to significantly improve survival of patients with fatal arrhythmia (abnormal heart rhythm) disorders.

Frontiers in Physiology, 2011 Prolonged out-of-hospital ventricular fibrillation (VF) arrests are associated with reduced ECG dominant frequency (DF) and diminished defibrillation success. Partial reversal of ischaemia increases ECG DF and improves defibrillation outcome.

Low energy defibrillation in human cardiac tissue: a simulation study [PDF]
, 2008 We aim to assess the effectiveness of feedback controlled resonant drift pacing as a method for low energy defibrillation. Antitachycardia pacing is the only low energy defibrillation approach to have gained clinical significance, but it is still suboptimal.

Optimizing low-energy anti-fibrillation pacing: Lessons from a cellular automaton model [PDF]
arXiv, 2021 The essential features of far-field low-energy defibrillation are elucidated using a simple cellular automaton model of excitable media. The model's topological character allows for direct correspondence with both realistic models and experiment. An optimal pacing period is shown to arise from the competition between two effects, and not a resonant ...

An Efficient Shock Advice Algorithm based on K-nearest Neighbors for Automated External Defibrillators [PDF]
arXiv, 2021 Shockable rhythms, namely ventricular fibrillation and ventricular tachycardia, are the main cause of sudden cardiac arrests, which can be detected quickly by the automated external defibrillator (AED) devices. In this paper, a simple but effective algorithm is proposed as the shock advice algorithm applied in AED.
