Atrial tachycardia in a patient with arrhythmogenic right ventricular cardiomyopathy/dysplasia

Journal of Arrhythmia, 2013
We describe a 49-year-old woman with atrial tachycardia (AT) and arrhythmogenic right ventricular cardiomyopathy/dysplasia. Cardiac magnetic resonance images showed a markedly dilated right atrium and right ventricle.

Catheter ablation of three macroreentrant atrial tachycardias after surgical repair of Double-Outlet Right Ventricle

Journal of Arrhythmia, 2012
A 54-year-old man with a surgically repaired double-outlet right ventricle (DORV) presented with palpitations and worsening right heart failure. His 12-lead ECG showed atrial tachycardia (AT) with an atrial cycle length (CL) of 300 ms and an inverted saw-

Prediction of Type and Recurrence of Atrial Fibrillation after Catheter Ablation via Left Atrial Electroanatomical Voltage Mapping Registration and Multilayer Perceptron Classification: A Retrospective Study

Sensors, 2022
Atrial fibrillation (AF) is a common cardiac arrhythmia and affects one to two percent of the population. In this work, we leverage the three-dimensional atrial endocardial unipolar/bipolar voltage map to predict the AF type and recurrence of AF in 1 ...

Noninvasive 3D Mapping and Ablation of Epicardial Premature Ventricular Contractions From the Endocardial Aspect of the Left Atrial Appendage

JACC: Case Reports, 2020
Ablation is an established treatment for ectopy originating from the left ventricle (LV). We report on a case of noninvasive 3-dimensional mapping locating the origin precisely in the epicardial LV summit area.

Electroanatomic Mapping of Cardiac Resynchronization Therapy [PDF]

Circulation, 2003
A 51-year-old man with a history of dilated cardiomyopathy presented with New York Heart Association Class III congestive heart failure. Despite optimal medical management, he continued to experience symptoms consistent with low-output failure: exertional dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.

Principal component analysis of atrial fibrillation: Inclusion of posterior ECG leads does not improve correlation with left atrial activity [PDF]

, 2015
Background Lead V? is routinely analysed due to its large amplitude AF waveform. V? correlates strongly with right atrial activity but only moderately with left atrial activity. Posterior lead V? correlates strongest with left atrial activity.

A case of successful radiofrequency catheter ablation for atrial tachycardia originating from the inferior vena cava using high-resolution mapping

Indian Pacing and Electrophysiology Journal, 2022
A 60-year-old man presented with sustained supraventricular tachycardia. Atrial tachycardia (AT), with the earliest atrial activation (EAA) occurring at the ostium of the coronary sinus, was reproducibly induced.Three-dimensional electroanatomical ...

Iron Deposition following Chronic Myocardial Infarction as a Substrate for Cardiac Electrical Anomalies: Initial Findings in a Canine Model [PDF]

, 2013
Purpose: Iron deposition has been shown to occur following myocardial infarction (MI). We investigated whether such focal iron deposition within chronic MI lead to electrical anomalies. Methods: Two groups of dogs (ex-vivo (n = 12) and in-vivo (n = 10))
