The Electrophysiology Experience in Patients With Ebstein's Anomaly Undergoing the da Silva Cone Repair at UPMC Children's Hospital of Pittsburgh

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction The da Silva Cone repair (CR) has demonstrated to be an effective intervention for Ebstein's anomaly (EA). Perioperative management can be complicated by arrhythmias, but previous studies showed improvement with preoperative catheter and intraoperative surgical ablation.

Severe congenital RYR1-associated myopathy complicated with atrial tachycardia and sinus node dysfunction: a case report

open access: yesItalian Journal of Pediatrics, 2019
Background Cardiac arrhythmias are sometimes encountered in patients with hereditary myopathies and muscular dystrophies. Description of arrhythmias in myopathies and muscular dystrophies is very important, because arrhythmias have a strong impact on the

Dominant Frequency Mapping as a Functional Tool for Substrate‐Guided Ventricular Tachycardia Ablation

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
Stimulus‐independent DF mapping integrates intracardiac signals with 3D anatomy to visualize high‐DF activity, with regions derived from SmartTouch and Pentaray catheters showing spatial correspondence with operator‐defined ablation sites. Quantitative analysis demonstrates higher proximity scores at ablation sites, low projection error, and good ...

Atrioventricular Node Slow‐Pathway Ablation Reduces Atrial Fibrillation Inducibility: A Neuronal Mechanism

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundRadiofrequency ablation (RFA) for atrioventricular nodal reentrant tachycardia appears to reduce atrial tachycardia, which might relate to parasympathetic denervation at cardiac ganglionated plexuses.

Prospective Trial of Radiofrequency Catheter Ablation of High Dominant Frequencies After Pulmonary Vein Isolation in Non‐Paroxysmal Atrial Fibrillation (PAD‐AF Trial): A Multicenter, Randomized Clinical Trial

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
In persistent AF, adjunctive dominant frequency‐guided ablation after pulmonary vein isolation did not significantly improve outcomes. Limited overlap between high‐frequency sites and low‐voltage areas suggests functional–structural dissociation, while right atrial low‐voltage burden predicts recurrence.

Atypical response of class IC atrial flutter to adenosine

open access: yesMonaldi Archives for Chest Disease, 2015
We report the case of a 67-year-old female with a wide QRS complex tachycardia at 180 bpm. A diagnosis of class IC atrial flutter with aberrant ventricular conduction caused by flecainide therapy was formulated.

Diagnosis and Treatment of Inappropriate Sinus Tachycardia

open access: yes, 2017
Inappropriate sinus tachycardia (IST) is a syndrome of cardiac and extracardiac symptoms characterized by rapid sinus heart rate at rest (>100 bpm) or with minimal activity and disproportionate to the physiologic demands. Patients with this unique and

Challenges of device therapy for ventricular tachycardia in the rate range of sinus rhythm

open access: yes, 1996
A method is described for patient-activated detection of ventricular tachycardia, under circumstances in which automatic algorithms fail. We present a case of a patient with an implanted defibrillator (Jewel PCD) who presented with symptomatic exercise ...

Prevalence and Recovery of Arrhythmia‐Induced Cardiomyopathy in Patients With Newly Diagnosed Heart Failure Using a Wearable Defibrillator: A Real‐World Cohort Study

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
This graphical abstract summarizes the study design and main findings in patients with newly diagnosed left ventricular systolic dysfunction and concomitant arrhythmia undergoing early rhythm control under wearable cardioverter‐defibrillator protection.

Arrhythmia Diagnosis Following an ICD Shock.

open access: yesIndian Pacing and Electrophysiology Journal, 2001
Stored electrograms show atrial fibrillation with rapid ventricular rates (top panel). Sufficient numbers of RR intervals meet the tachycardia detection criteria initiating a train of anti-tachycardia pacing by the ICD (after the 8th electrogram in the ...
