Ehjcardiovascrec

Abstract Aims Previous studies showed that autonomic activation by high-frequency electrical stimulation (HFS) during myocardial refractoriness evokes rapid firing from pulmonary vein (PV) and atria, ...

Ehjcardiovascrec

A substrate for atrial propensity to AF is required for AF initiation and maintenance. [...]we reviewed and discussed mainly the electrophysiological properties observed in ...

Ehjcardiovascrec

Abstract In the heart, changes in velocity and in patterns of conduction of myocardial electrical activity can affect cardiac rhythm and the coordination of contraction. Gap junctions are clusters ...

Ehjcardiovascrec

Methods and results: 12 rabbit heart preparations were used to evaluate the ventricular rate during programmed regular high atrial rate pacing or random pacing from eight atrial sites. Conclusions: ...

Ehjcardiovascrec

For patients and physicians it remains frequently disabling, responsible for extra cost, morbidity and probably mortality, and often very frustrating [28]. The number of centers involved in a ...

Ehjcardiovascrec

Introduction Atrial fibrillation (AF) represents the most common rhythm disorder with a life-time risk for those reaching 40 years of age of 25% in Europe and the USA.1 This arrhythmia is associated ...

Ehjcardiovascrec

Abstract Objective: Although the incidence of atrial fibrillation (AF) increases with age, the cellular electrophysiological changes that render the atria of aged individuals more susceptible to AF ...

Ehjcardiovascrec

[...]we tested the hypothesis that a rare stimulation pattern might alter the myocardial substrate, making it more susceptible to the initiation of arrhythmias. Methods: In isolated right and left ...

Ehjcardiovascrec

The ability to study the importance of a single gene product in pathophysiology make this a potentially powerful tool to understand the causal relationship of several proteins and the substrate for ...
