Minimally invasive, pericardial implantable cardioverter-defibrillator placement in a young child

Journal of Arrhythmia, 2017
We report the successful minimally invasive placement of a pericardial implantable cardioverter-defibrillator (ICD) in a 16-kg child. A transvenous ICD dual coil was advanced through a small subxiphoid incision and screwed into the oblique sinus ...

Nanosecond Stimulation and Defibrillation of Langendorff-Perfused Rabbit Hearts [PDF]

, 2020
The search for novel defibrillation methodologies focuses on minimizing deposition of energy to the heart, as this is an indicator for side effects including pain and tissue death.

Defibrillation thresholds testing of implantable cardioverter-defibrillators at implantation

Journal of the American College of Cardiology, 2005
I read with interest the reports on defibrillation testing (DFT) during implantable cardioverter-defibrillator (ICD) implantation published recently in JACC ([1,2][1]). There is a significant, albeit low, risk to serious complications including death during DFT testing.

Clinical predictors of the defibrillation threshold with the unipolar implantable defibrillation system

Journal of the American College of Cardiology, 1995
The purpose of this study was to determine the relation between clinical variables and the defibrillation threshold by using a standardized testing protocol and a uniform implantable defibrillator system.Past studied have not revealed useful correlations between clinical variables and the energy required to terminate ventricular fibrillation.

Cardiac rhythm devices in heart failure with reduced ejection fraction – role, timing, and optimal use in contemporary practice. European Journal of Heart Failure expert consensus document

European Journal of Heart Failure, EarlyView.
Abstract Guidelines for management of heart failure with reduced ejection fraction (HFrEF) emphasize personalized care, patient engagement, and shared decision‐making. Medications and cardiac rhythm management (CRM) devices are recommended with a high level of evidence. However, there are significant disparities: patients who could benefit from devices

Model-based Pre-clinical Trials for Medical Devices Using Statistical Model Checking [PDF]

arXiv, 2021
Clinical trials are considered as the golden standard for medical device validation. However, many sacrifices have to be made during the design and conduction of the trials due to cost considerations and partial information, which may compromise the significance of the trial results. In this paper, we proposed a model-based pre-clinical trial framework

The Automatic External Cardioverter-Defibrillator [PDF]

, 2004
In-hospital cardiac arrest remains a major problem but new technologies allowing fully automatic external defibrillation are available. These technologies allow the concept of “external therapeutic monitoring” of lethal arrhythmias.

Double and triple sequential shocks reduce ventricular defibrillation threshold in dogs with and without myocardial infarction [PDF]

, 1986
The role of optimal placement of electrodes and mode of shock delivery from a defibrillator was examined in dogs with and without myocardial infarction.

The use of left ventricular ejection fraction in the diagnosis and management of heart failure. A clinical consensus statement of the Heart Failure Association (HFA) of the ESC, the Heart Failure Society of America (HFSA), and the Japanese Heart Failure Society (JHFS)

European Journal of Heart Failure, EarlyView.
Abstract This clinical consensus statement revisits the role of left ventricular ejection fraction (LVEF) as a measurement of cardiac function, a prognostic marker and a major criterion to classify patients with heart failure, and gives new advice for clinical practice.

Ultra-low-energy defibrillation through adjoint optimization [PDF]

This study investigates ultra-low-energy defibrillation protocols using a simple two-dimensional model of cardiac tissue. We find that, rather counter-intuitively, a single, properly timed, biphasic pulse can be more effective in defibrillating the tissue than low energy antitachycardia pacing (LEAP) which employs a sequence of such pulses, succeeding ...
