Real‐Time Ventricular Fibrillation Amplitude‐Spectral Area Analysis to Guide Timing of Shock Delivery Improves Defibrillation Efficacy During Cardiopulmonary Resuscitation in Swine [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundThe ventricular fibrillation amplitude spectral area (AMSA) predicts whether an electrical shock could terminate ventricular fibrillation and prompt return of spontaneous circulation.

Out-of-Hospital Cardiac Arrest in Ireland 2012 to 2020: Bystander CPR, bystander defibrillation and survival in the Utstein comparator group

Resuscitation Plus
Background: The Irish Out-of-Hospital Cardiac Arrest registry (OHCAR) collects data based on the internationally recognised Utstein template. The Utstein comparator group (bystander witnessed and initial shockable rhythm) has specific relevance in ...

Association between the number of prehospital defibrillation attempts and neurologic outcomes in out-of-hospital cardiac arrest patients without on-scene return of spontaneous circulation [PDF]

Clinical and Experimental Emergency Medicine, 2021
Objective Delivery of prehospital defibrillation for shockable rhythms by emergency medical service providers is crucial for successful resuscitation in out-of-hospital cardiac arrest (OHCA) patients.

A framework of current based defibrillation improves defibrillation efficacy of biphasic truncated exponential waveform in rabbits

Scientific Reports, 2021
Defibrillation is accomplished by the passage of sufficient current through the heart to terminate ventricular fibrillation (VF). Although current-based defibrillation has been shown to be superior to energy-based defibrillation with monophasic waveforms,

DOuble SEquential External Defibrillation for Refractory Ventricular Fibrillation (DOSE VF): study protocol for a randomized controlled trial

Trials, 2020
Background Despite high-quality cardiopulmonary resuscitation (CPR), early defibrillation, and antiarrhythmic medications, some patients remain in refractory ventricular fibrillation (VF) during out-of-hospital cardiac arrest.

Factors associated with delayed defibrillation in cardiopulmonary resuscitation: A prospective simulation study. [PDF]

PLoS ONE, 2017
Early defibrillation is an important factor of survival in cardiac arrest. However, novice resuscitators often struggle with cardiac arrest patients.

Comparison of Resuscitation Outcomes Between 2‐ or 3‐Stacked Defibrillation Strategies With Minimally Interrupted Chest Compression and the Single Defibrillation Strategy: A Swine Cardiac Arrest Model

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background There is controversy over whether the number and mode of electrical shock are optimal for successful defibrillation. Methods and Results Fifty‐four pigs were randomly assigned to 3 groups. After inducing ventricular fibrillation and a 2‐minute

Extended charge banking model of dual path shocks for implantable cardioverter defibrillators

BioMedical Engineering OnLine, 2008
Background Single path defibrillation shock methods have been improved through the use of the Charge Banking Model of defibrillation, which predicts the response of the heart to shocks as a simple resistor-capacitor (RC) circuit.

Electroporation safety factor of 300 nanosecond and 10 millisecond defibrillation in Langendorff-perfused rabbit hearts.

PLoS ONE, 2021
AimsRecently, a new defibrillation modality using nanosecond pulses was shown to be effective at much lower energies than conventional 10 millisecond monophasic shocks in ex vivo experiments.
