The year in cardiology: arrhythmias and pacing. [PDF]

, 2020
During this last year, there has been much progress with regard to anticoagulant and ablation therapy for atrial fibrillation (AF). Apart from recently issued European Society of Cardiology Guidelines for the management of patients with supraventricular ...

Conversational Atrial Tachycardia

Journal of the American College of Cardiology, 2012
![Figure][1] [![Graphic][3] ][3] A 63-year-old man with history of paroxysmal atrial fibrillation presented with symptoms of dyspnea and dizziness for several weeks. Curiously, these symptoms occurred only while he was speaking.

A case of an atrial tachycardia originating from an occluded coronary sinus ostium with a persistent left superior vena cava

Indian Pacing and Electrophysiology Journal, 2017
We present a case of a 37-year-old female who complained of frequent palpitations caused by an atrial tachycardia and atrial premature contractions. Angiography revealed that the coronary sinus was occluded at the ostium and connected to a persistent ...

Clinical and Electrophysiological Correlates of Incessant Ivabradine-Sensitive Atrial Tachycardia.

Circulation: Arrhythmia and Electrophysiology, 2019
BACKGROUND Incessant focal atrial tachycardia (FAT), if untreated, can lead to ventricular dysfunction and heart failure (tachycardia-induced cardiomyopathy). Drug therapy of FAT is often difficult and ineffective. The efficacy of ivabradine has not been

Persistent Atrial Tachycardia Mimicking Inappropriate Sinus Tachycardia: A Case Report

Journal of Arrhythmia, 2011
We report on a 57-year-old man with atrial tachycardia mimicking inappropriate sinus tachycardia that was sustained for 4 months despite pharmacotherapy.

A study on stability analysis of atrial repolarization variability using ARX model in sinus rhythm and atrial tachycardia ECGs [PDF]

, 2016
© 2016 Elsevier Ireland Ltd Background The interaction between the PTa and PP interval dynamics from the surface ECG is seldom explained. Mathematical modeling of these intervals is of interest in finding the relationship between the heart rate and ...

Scar identification, quantification, and characterization in complex atrial tachycardia: a path to targeted ablation?

Europace, 2019
Successful catheter ablation of scar-related atrial tachycardia depends on correct identification of the critical isthmus. Often, this is a represented by a small bundle of viable conducting tissue within a low-voltage area.

Adenosine Triphosphate-sensitive Micro-reentrant Atrial Tachycardia Originating from the Crista Terminalis in a Patient with Chronic Renal Failure due to Thrombotic Thrombocytopenic Purpura

Journal of Arrhythmia, 2009
A 57-year-old woman with chronic renal failure due to the thrombotic thrombocytopenic purpura complained of palpitation. A 12-lead ECG showed supraventricular tachycardia with a cycle length of 375 ms. During the electrophysiological study, a tachycardia

Nonreentrant atrial tachycardia occurs independently of hypertrophic cardiomyopathy in RASopathy patients

American Journal of Medical Genetics. Part A, 2018
Multifocal atrial tachycardia (MAT) has a well‐known association with Costello syndrome, but is rarely described with related RAS/MAPK pathway disorders (RASopathies).

Electrocardiographic patch devices and contemporary wireless cardiac monitoring. [PDF]

, 2015
Cardiac electrophysiologic derangements often coexist with disorders of the circulatory system. Capturing and diagnosing arrhythmias and conduction system disease may lead to a change in diagnosis, clinical management and patient outcomes.
