Chaos control in cardiac dynamics: terminating chaotic states with local minima pacing
Current treatments of cardiac arrhythmias like ventricular fibrillation involve the application of a high-energy electric shock, that induces significant electrical currents in the myocardium and therefore involves severe side effects like possible ...

Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram [PDF]
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy are sufficiently predictable by clinical and echocardiographic parameters.

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York
Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

High-voltage defibrillator unit with increased energy output from a controlled capacitor storage
Introduction. It is known that the combination of the main parameters of the defibrillation pulse, such as its duration, leading edge steepness, current amplitude, energy and shape, phase amplitude ratio, should provide a therapeutic effect with minimal ...

Evaluation of Impact of Some Pulse Parameters on the Efficiency of Electric Cardiac Defibrillation
Objective: to test the hypothesis of the resonance pattern of an electric cardiac defibrillation process and to study the impact of the frequency spectrum of pulses of various shape on the efficiency of defibrillation.Material and methods.

The Automatic External Cardioverter-Defibrillator [PDF]
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.

Abstract Socio‐economic status (SES) has been associated with incident and prevalent heart failure (HF), as well as its morbidity and mortality. However, the precise nature of the relationship between SES and HF remains unclear due to inconsistent data. This study aims to provide a comprehensive assessment and data synthesis of the relationship between

Myocardial dysfunction after out-of-hospital cardiac arrest: predictors and prognostic implications. [PDF]
We aim to determine the incidence of early myocardial dysfunction after out-of-hospital cardiac arrest, risk factors associated with its development, and association with outcome.

Nonlinear physics of electrical wave propagation in the heart: a review [PDF]
The beating of the heart is a synchronized contraction of muscle cells (myocytes) that are triggered by a periodic sequence of electrical waves (action potentials) originating in the sino-atrial node and propagating over the atria and the ventricles ...
