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

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.

Optimal allocation of defibrillator drones in mountainous regions [PDF]

, 2019
Responding to emergencies in Alpine terrain is quite challenging as air ambulances and mountain rescue services are often confronted with logistics challenges and adverse weather conditions that extend the response times required to provide life-saving support.

Control of spiral waves and turbulent states in a cardiac model by travelling-wave perturbations [PDF]

Chinese Physics, 12, 674 (2003), 2003
We propose a travelling-wave perturbation method to control the spatiotemporal dynamics in a cardiac model. It is numerically demonstrated that the method can successfully suppress the wave instability (alternans in action potential duration) in the one-dimensional case and convert spiral waves and turbulent states to the normal travelling wave states ...

Azygos Vein Lead Implantation For High Defibrillation Thresholds In Implantable Cardioverter Defibrillator Placement [PDF]

Indian Pacing and Electrophysiology Journal, 2010
Evaluation of defibrillation threshold is a standard of care during implantation of implantable cardioverter defibrillator. High defibrillation thresholds are often encountered and pose a challenge to electrophysiologists to improve the defibrillation ...

Evaluation of factors associated with selection for coronary angiography and in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest without ST‐segment elevation

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1159-1170, December 1, 2022., 2022
Abstract Background Clinical factors favouring coronary angiography (CA) selection and variables associated with in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest (OHCA) without ST‐segment elevation (STE) remain unclear.

Transcatheter valve repair of tricuspid regurgitation with the PASCAL system: TriCLASP study 30‐day results

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1291-1299, December 1, 2022., 2022
Abstract Background Severe tricuspid regurgitation (TR) is independently associated with increased morbidity and mortality. Percutaneous transcatheter approaches may offer an alternative for patients not amenable to surgery. Methods TriCLASP is a prospective, single‐arm, multicenter European post‐market clinical follow‐up study (NCT04614402) to ...

The mortality for the implantable cardiac defibrillator in nonischemic cardiomyopathy: An updated systematic review and meta‐analysis

Clinical Cardiology, Volume 45, Issue 12, Page 1163-1170, December 2022., 2022
Abstract The implantable cardiac defibrillator (ICD) is common for the management of nonischemic cardiomyopathy (NICM). Mortality is a crucial issue for patients with NICM. We can understand the mortality events of ICD versus medicine treatment via a systemic review and meta‐analysis of randomized clinical trials.

Prognostic value of global longitudinal strain in hypertrophic cardiomyopathy: A systematic review and meta‐analysis

Clinical Cardiology, Volume 45, Issue 12, Page 1184-1191, December 2022., 2022
Abstract Background As previously reported, impairment of left ventricular global longitudinal strain (LVGLS) is associated with myocardial fibrosis, arrhythmias, and heart failure in hypertrophic cardiomyopathy (HCM) patients. Hypothesis This study aimed to estimate the association between LVGLS measured by echocardiography and major adverse ...

Drift and termination of spiral waves in optogenetically modified cardiac tissue at sub-threshold illumination

eLife, 2021
The development of new approaches to control cardiac arrhythmias requires a deep understanding of spiral wave dynamics. Optogenetics offers new possibilities for this.

The Effect of Compressor-Administered Defibrillation on Peri-shock Pauses in a Simulated Cardiac Arrest Scenario

Western Journal of Emergency Medicine, 2014
Introduction: Coordination of the tasks of performing chest compressions and defibrillation can lead to communication challenges that may prolong time spent off the chest.
