The rhythms of rhythm [PDF]

open access: yesJournal of the International Phonetic Association, 2021
The low frequency (LF) spectral analysis or ‘rhythm spectrum’ approach to the quantitative analysis and comparison of speech rhythms is extended beyond syllable or word rhythms to ‘rhetorical rhythms’ in read-aloud narratives, in a selection of exploratory scenarios, with the aim of developing a unified theory of speech rhythms.

Incidence, electrophysiological characteristics, and long‐term follow‐up of perimitral atrial flutter in patients with previously confirmed mitral isthmus block

open access: yesJournal of Arrhythmia, 2021
Introduction After mitral isthmus (ΜΙ) catheter ablation, perimitral atrial flutter (PMF) circuits can be maintained due to the preservation of residual myocardial connections, even if conventional pacing criteria for complete MI block are apparently met

A novel stepwise approach incorporating ethanol infusion in the vein of Marshall for the ablation of persistent atrial fibrillation

open access: yesFrontiers in Cardiovascular Medicine, 2023
IntroductionApart from pulmonary vein isolation (PVI), several step-by-step procedures that aim to modify left atrial substrate have been proposed for the ablation of persistent atrial fibrillation (AF), yet the optimal strategy remains elusive.

Anemia and iron deficiency in patients with atrial fibrillation

open access: yesBMC Cardiovascular Disorders, 2022
Atrial fibrillation (AF) is the most common cardiac tachyarrhythmia and has a rising global prevalence. Given the increasing burden of AF-related symptoms and complications, new approaches to management are required. Anemia and iron deficiency are common

The Electrophysiology of Atrial Fibrillation: From Basic Mechanisms to Catheter Ablation

open access: yesCardiology Research and Practice, 2021
The electrophysiology of atrial fibrillation (AF) has always been a deep mystery in understanding this complex arrhythmia. The pathophysiological mechanisms of AF are complex and often remain unclear despite extensive research.

Current Mechanistic and Pharmacodynamic Understanding of Melanocortin-4 Receptor Activation

open access: yesMolecules, 2019
In this work we summarize our understanding of melanocortin 4 receptor (MC4R) pathway activation, aiming to define a safe and effective therapeutic targeting strategy for the MC4R.

Conversion of atrial fibrillation to sinus rhythm during cryoballoon ablation: A favorable and not unusual phenomenon during second‐generation cryoballoon pulmonary vein isolation

open access: yesJournal of Arrhythmia, 2020
Background The prevalence and the clinical impact of conversion of atrial fibrillation (AF) to sinus rhythm (SR) during cryoballoon ablation (CB‐A) are unknown.

Ventricular ectopy from the non-coronary cusp: Pathophysiological and anatomical considerations

open access: yesIndian Pacing and Electrophysiology Journal, 2021
Non-coronary cusp (NCC) is a rare site for ventricular arrhythmias because it does not come into direct contact with the ventricular myocardium. Instead, the NCC comes in contact with the membranous septum near the His region.
