Defibrillation and cardioversion [PDF]

Cardiovascular Research, 2001
Going back to the ‘archaic past and to obsolete ancestors’ [1] provides insight not only where we came from but where we might be heading. Indeed history matters in medicine as it does in everyday life. It is now 40 years since the introduction of DC defibrillation and cardioversion [2,3].

Environmentally Friendly Nanofiber Cellulose From Durian Rinds: A Sustainable Alternative Biomass Resource

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A novel, efficient, and eco‐friendly sustainable process has been developed for the extraction of cellulose nanofibers (CNF) from durian rinds. The method utilizes low‐molecular‐weight 2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPO) as an oxidation agent, in conjunction with sonication treatment, resulting in a significant reduction of processing

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Implantable cardioverter defibrillators for the treatment of arrhythmias and cardiac resynchronisation therapy for the treatment of heart failure: systematic review and economic evaluation [PDF]

, 2014
Background This assessment updates and expands on two previous technology assessments that evaluated implantable cardioverter defibrillators (ICDs) for arrhythmias and cardiac resynchronisation therapy (CRT) for heart failure (HF).

The topology of defibrillation [PDF]

Journal of Theoretical Biology, 2004
We describe how Art Winfree's ideas about phase singularities can be used to understand the response of cardiac tissue with a random preexisting pattern of reentrant waves (fibrillation) to a large brief current stimulus. This discussion is organized around spatial dimension, beginning with a discussion of reentry on a periodic ring, followed by ...

Contemporary and Emerging Therapies in the Management of Refractory Angina: A Clinical Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Refractory angina (RA) represents a growing challenge in clinical cardiology, particularly in patients with obstructive coronary artery disease (CAD) who remain symptomatic despite optimal medical therapy and who are not candidates for revascularization.

Slowing of electrical activity in ventricular fibrillation is not associated with increased defibrillation energies in the isolated rabbit heart

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.

Deep Neural Networks for ECG-Based Pulse Detection during Out-of-Hospital Cardiac Arrest [PDF]

, 2019
The automatic detection of pulse during out-of-hospital cardiac arrest (OHCA) is necessary for the early recognition of the arrest and the detection of return of spontaneous circulation (end of the arrest).

The difficult discussion on the deactivation of implantable cardioverter devices at the end of life: a systematic review

ESC Heart Failure, Volume 12, Issue 2, Page 733-760, April 2025.
Abstract Implantable cardioverter defibrillators (ICDs) reliably prevent death due to life‐threatening arrhythmias; this may become less relevant in people with more severe heart failure who are reaching the end of life (EOL). This review aimed to explore the ICD deactivation process and identify ethical issues, especially around the initiation of ...
