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.

Transient outward K+ current (ITO) reduction prolongs action potentials and promotes afterdepolarisations: a dynamic-clamp study in human and rabbit cardiac atrial myocytes [PDF]

, 2012
Background and aim: Human atrial transient outward K+ current (ITO) is decreased in a variety of cardiac pathologies, but how ITO reduction alters action potentials (AP) and arrhythmia mechanisms is poorly understood, owing to non-selectivity of ITO ...

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

HL-1 cells express an inwardly rectifying K+ current activated via muscarinic receptors comparable to that in mouse atrial myocytes [PDF]

, 2010
An inwardly rectifying K^+ current is present in atrial cardiac myocytes that is activated by acetylcholine (I_{KACh}). Physiologically, activation of the current in the SA node is important in slowing the heart rate with increased parasympathetic tone ...

Trends in atrial flutter and atrial tachycardia research

Informatics in Medicine Unlocked, 2017
Background: Atrial flutter and atrial tachycardia are frequently observed arrhythmias that can be difficult to treat effectively with catheter ablation. It would be of interest to know the research directions for these arrhythmias in order to plan future

Catheter ablation for atrial tachycardia in pediatric patients: a single-center experience

Frontiers in Cardiovascular Medicine
PurposeAtrial tachycardia is an uncommon supraventricular tachycardia in children. It is often drug-resistant and likely to occur concomitantly with tachycardia-induced cardiomyopathy, making radiofrequency catheter ablation the preferred treatment.

Semi-urgent pulmonary vein isolation using cryoballoon for haemodynamically unstable atrial fibrillation storm in a patient with low cardiac output syndrome: a case report

BMC Cardiovascular Disorders, 2020
Background Atrial fibrillation and heart failure are common coexisting conditions requiring hospitalisation for heart failure and death. Pulmonary vein isolation is a well-established option for symptomatic atrial fibrillation and for atrial fibrillation

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Successful hot balloon ablation for focal atrial tachycardia derived from the left superior pulmonary vein antrum

Journal of Arrhythmia, 2020
A 45‐year‐old man with paroxysmal atrial fibrillation (PAF) was admitted to our hospital for hot balloon ablation. At admission, atrial tachycardia (AT) was observed.
