New Paradigm of Defibrillation: Towards Painless Therapy
… atrial tachyarrhythmias and the mechanisms of defibrillation using the conventional high-voltage single shock. Through the use of novel fluorescent optical mapping techniques and several animal models of ventricular and atrial arrhythmias, we develop and validate several novel low-voltage …

An analysis of defibrillation and cardiac resynchronization therapy strategies in patients with failing systemic right ventricles
… Endocardial, epicardial and transthoracic defibrillation strategies were examined in 5 consecutive cases. A hybridized form of CRT was employed in two patients. Only one patient demonstrated response to therapy while the other deteriorated during biventricular pacing (BVP). This prompted a …

Adaptive defibrillator design
… with myocardivim abnormalities. Electrical defibrillation is usually achieved by passing an electrical current pulse transthoracically through the heart of the patient. The source of this electrical current is usually a high voltage capacitor. The successful operation of defibrillators …

A study of defibrillator waveforms, vectors, and therapies Kevin Anthony Michael.
The defibrillation studies were performed in a porcine model given its resemblance to the human heart and its resilience to repeated ventricular fibrillation inductions (VF) and defibrillations. A novel sequential preshock waveform was assessed in a prototype serial capacitance device. Single and …

LUCAS - Lund University Cardiopulmonary Assist System
… will increase if LUCAS-CPR is given before defibrillation, and if defibrillation is given during on-going chest compressions. 4. LUCAS-CPR will cause fewer rib fractures than manual CPR. LUCAS-CPR gave significantly higher rates of ROSC and significantly higher CPP than manual CPR. LUCAS-CPR …

High Resolution Multi-parametric Diagnostics and Therapy of Atrial Fibrillation: Chasing Arrhythmia Vulnerabilities in the Spatial Domain
… becomes a significant concern for electrical defibrillation of AF due to the fact that a patient is conscious when experiencing the arrhythmia. Limiting the risk of myocardial injury is key for both forms of fibrillation. In this project we aim to address the limitations of current …

Atrial Arrhythmogenic Substrates: The Role of Structure and Molecular Remodeling
… explore the application of a novel low-voltage defibrillation therapy to a rabbit model of atrial tachyarrhythmias and show significant reductions in the defibrillation threshold for both AF and AFl. We utilize a variety of experimental techniques, such as high throughput quantitative PCR, …

Bedarf und ideale Standorte von automatisierten externen Defibrillatoren im Kreis Düren : eine retrospektive Analyse von 560 außerklinischen Reanimationsverläufen im Kreis Düren im Zeitraum vom 01.01.2002 bis 31.12.2005
… rhythm in out-of-hospital cardiac arrest, defibrillation is essential. For several years, Automated External Defibrillators (AED) are available which enable defibrillation by other groups than physicians and healthcare professionals. In order to intend the need and a possible selection of …

Study of the Kalman filter for arrhythmia detection with intracardiac electrograms
… to reverse ventricular fibrillation (VF) by defibrillation and ventricular tachycardia (VT) by low-energy cardioversion or antitachycardia pacing. The schemes for detecting cardiac arrhythmias often realize nonpathologic tachycardia as serious arrhythmias and deliver false shocks. In this …

Isolation of Cellulose Nanofibres: Elucidation of a Novel Approach Utilizing Fungal Pretreatment
… is investigated which can bring about internal defibrillation in the fibres through reduction of hydrogen bonds and cleavage of hemicellulose chains tethering the cellulose microfibrils together. The pre-treatment of wood fibres with Ophiostoma Ulmi, a causative agent of Dutch elm disease in Elm …

Human Factors in Drone Delivery of Automatic External Defibrillators for Out of Hospital Cardiac Arrest: Older Adult Considerations
… Cardiac Arrests (OHCA) due to earlier access to defibrillation. There is a lack of user-centred, and older adult-focused research in this area. The present study evaluated the perceptions and interactions of older adults with a drone delivered AED operation to identify human factors …

The Experiences of Women Who Live with an Implantable Cardioverter-Defibrillator (lCD)
… these arrhythmias by pacing, cardioversion, and defibrillation thereby providing lifesaving therapy to patients at risk for sudden cardiac death. Currently, 150,000 Americans receive ICDs each year. Although most lCD recipients are men, more women are now qualifying for insertion (Stutts, Cross, …

Prehospital Care of Out-of-Hospital Cardiac Arrest Patients
… was ventricular fibrillation in 22 (29.3%) cases,defibrillation performed in the ambulance were 4 (18.2%) cases. CONCLUSION: By stander and 119 resuscitation were not satisfactory in the care of the out-of-hospital cardiac arrests.Witnessed arrest and bystander CPR did not significantly affect the …

Validation of weight estimation by age and length based methods in the South African population

Predictors of survival in cardiac arrest
… and then age. The delays to start of CPR and to defibrillation were short in the majority of patients, which may explain why delay was not the most important factor for outcome. Gender did not seem important when using ML. Study III examines ca 22,000 bystander-witnessed cases of OHCA to …
