Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram [PDF]

open access: yes, 2004
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.

The Clinical Utility of 3D Electroanatomical Mapping for Atrial Fibrillation Ablation by Pulsed Field Ablation

open access: yesJournal of Arrhythmia, Volume 41, Issue 6, December 2025.
Systematic high‐density 3D electroanatomical remapping during pulsed field ablation detected residual conduction in 9% of cases, predominantly in the right superior pulmonary vein. Detailed voltage analysis demonstrated sharp 1 mm lesion borders, highlighting the value of 3D mapping for assessing lesion integrity and procedural endpoints in pulsed ...

Cardiac Arrhythmia and Geomagnetic Activity [PDF]

open access: yes, 2006
Background: The purpose of this paper is a review of a number of studies considering links between life threatening cardiac arrhythmias, sudden cardiac death (SCD) and the level of environmental physical activity factors like geomagnetic activity (GMA)

Clinical Profiles and In‐Hospital Outcomes of Pre‐Existing Versus Newly Diagnosed Atrial Fibrillation in Coronary Care Units: Insights From the MORCOR‐TURK National Registry

open access: yesJournal of Arrhythmia, Volume 41, Issue 6, December 2025.
MORCOR‐TURK National Registry Study: In Turkish coronary care units, newly diagnosed atrial fibrillation, compared with pre‐existing AF, is associated with a higher inflammatory burden (CRP 28.4 vs. 12.6 mg/L), elevated NT‐proBNP levels, and approximately double the in‐hospital mortality (12.0% vs. 6.8%).

Paroxysmal supraventricular tachycardias: modern principles of diagnostics and treatment

open access: yesКардиоваскулярная терапия и профилактика, 2005
The article is devoted to one of the most actual problems in modern arrhythmology - treatment of paroxysmal supraventricular tachycardias. Modern views on diagnostics and treatment of atrio-ventricular (AV) nodal reciprocating tachycardia and AV ...

The QT interval in lightning injury with implications for the cessation of metabolism hypothesis [PDF]

open access: yes
An hypothesis is presented to provide an alternative to the Cessation of Metabolism hypothesis often invoked in lightning injury. Cessation of Metabolism has been proposed to explain the observation of good recovery after a prolonged period in cardiac ...

The Postural Tachycardia Syndrome (POTS): Pathophysiology, Diagnosis & Management [PDF]

open access: yes, 2006
Postural tachycardia syndrome (POTS), characterized by orthostatic tachycardia in the absence of orthostatic hypotension, has been the focus of increasing clinical interest over the last 15 years 1. Patients with POTS complain of symptoms of tachycardia,

Beyond the Pulmonary Veins: The Influence of Pulsed Field Ablation on the Superior Vena Cava

open access: yesJournal of Arrhythmia, Volume 41, Issue 6, December 2025.
Pulsed field ablation at the right superior pulmonary vein frequently causes conduction delay or partial isolation of the superior vena cava. Anatomical proximity between the two structures, as assessed by preprocedural CT, predicts the likelihood of SVC involvement.

Anteroposterior Diameter of the Left Atrium Determines the Occurrence of Left Atrial Tachycardia in Non-paroxysmal Atrial Fibrillation Patients after Catheter Ablation

open access: yesMajalah Kardiologi Indonesia
Objectives:             The relationship between left atrial (LA) size and atrial fibrillation (AF) is well-established. However, the specifics of LA regional remodeling and its connection to left atrial tachycardia (LA-AT) post-ablation in patients ...
