The Ž eld of cardiac electrophysiology has grown and changed dramatically since the last guideline on fellowship training objectives was published in 1988. Not only has the ability to diagnose arrhythmic diseases improved, but also the knowledge of genetic contributions and mechanisms of these disorders has expanded. Moreover, the treatment of these arrhythmias, including ablation and implantab...

Space-fractional operators have been used with success in a variety of practical applications to describe transport processes in media characterised by spatial connectivity properties and high structural heterogeneity altering the classical laws of diffusion. This study provides a systematic investigation of the spatio-temporal effects of a space-fractional model in cardiac electrophysiology. W...

The parasympathetic nervous system plays an important role in the pathophysiology of atrial fibrillation. Catheter ablation, a minimally invasive procedure deactivating abnormal firing cardiac tissue, is increasingly becoming the therapy of choice for atrial fibrillation. This is inevitably associated with the obliteration of cardiac cholinergic neurons. However, the impact on ventricular elect...

Telemetric ECG recording in mice is essential to understanding the mechanisms behind arrhythmias, conduction disorders, and sudden cardiac death. Although the surface ECG is utilized for short-term measurements of waveform intervals, it is not practical for long-term studies of heart rate variability or the capture of rare episodes of arrhythmias. Implantable ECG telemeters offer the advantages...

Personalized cardiac electrophysiology simulations have demonstrated great potential to study arrhythmias and help in therapy planning of radio-frequency ablation. Its application analyze vulnerability ventricular tachycardia sudden death infarcted patients has been recently explored. However, the detailed multi-scale biophysical used these studies are very demanding terms memory computational ...

Systematic national effort to improve cardiac electrophysiology practice in Lebanon is lacking, and the quality improvement program mainly relates to individual efforts along with regulations, which are set as a "Road Map" by the Lebanese Arrhythmia Working Group. Lebanon currently has five electrophysiology laboratories. The "Road Map" mainly consists of creating a registry and a National Card...

We consider an inverse problem regarding the detection of small conductivity inhomogeneities in a boundary value for semilinear elliptic equation. For such problem, that is related to cardiac electrophysiology, asymptotic expansion potential due presence was established [4]. Starting from this we derive Lipschitz continuous ...

BACKGROUND Recent studies have shown that insertable cardiac monitors (ICMs) can be implanted out of the traditional hospital setting and efforts are being made to explore the feasibility of implanting these devices in a specific standardized location other than the operating room or a cardiac catherization/electrophysiology lab. METHODS This was a prospective, non-randomized, single center p...
