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

Journal 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.

Impact of Left Bundle Branch Area Pacing on Echocardiographic Parameters and Symptoms: Data From the Conduction System Pacing Italian Network Group (C‐SING) Study

Journal of Cardiovascular Electrophysiology, EarlyView.
Left bundle branch area pacing is associated with preservation of ventricular function in patients with bradycardia indications and with significant reverse remodeling and symptomatic improvement in patients with heart failure. Maintaining a high percentage of effective LBBAP capture is critical to minimize the risk of pacing‐induced cardiomyopathy and

A curious alliance: Sinus nodal dysfunction precipitating atrioventricular block

Journal of Arrhythmia, 2014
An elderly woman presented with recurrent syncope. Sinus bradycardia and sinoatrial block were seen on the electrocardiogram; however, PR interval prolongation after sinus pauses suggested atrioventricular conduction system disease.

Sinus node dysfunction following targeted disruption of the murine cardiac sodium channel gene Scn5a

, 2005
We have examined sino-atrial node (SAN) function in hearts from adult mice with heterozygous targeted disruption of the Scn5a gene to clarify the role of Scn5a-encoded cardiac Na+ channels in normal SAN function and the mechanism(s) by which reduced Na ...

Impact of Left Bundle Branch Pacing on Left Ventricular Mechanical Efficiency

Journal of Cardiovascular Electrophysiology, EarlyView.
The analysis of myocardial work in 115 consecutive patients receiving left bundle branch area pacing revealed a strong correlation between all myocardial work indices recorded during spontaneous or paced rhythm. Conversely, no significant correlations were observed between myocardial work indices and the R wave peak time in V6 or the V6–V1 interpeak ...

Annual Research Review: What processes are dysregulated among emotionally dysregulated youth? – a systematic review

Journal of Child Psychology and Psychiatry, Volume 66, Issue 4, Page 516-546, April 2025.
Proliferation of the term “emotion dysregulation” in child psychopathology parallels the growing interest in processes that influence negative emotional reactivity. While it commonly refers to a clinical phenotype where intense anger leads to behavioral dyscontrol, the term implies etiology because anything that is dysregulated requires an impaired ...
