Abstract: null null Background null Junctional ectopic tachycardia (JET) is a common arrhythmia following congenital heart disease (CHD) surgery. There is variability in choice of antiarrhythmic therapy, with amiodarone used commonly. Intravenous (IV) sotalol is a newly available agent which may be useful for JET. null null null Objective null To evaluate the safety of efficacy of IV sotalol for postoperative JET and compare outcomes with IV amiodarone. null null null Methods null Retrospective ...
ABSTRACTS: null Background null Bradyarrhythmias leading to permanent pacemaker (PPM) continue to be a complication after Transcatheter Aortic Valve Replacement (TAVR) null Objectives null To assess the prevalence of bradyarrhythmias using ECG extended rhythm recording among patients pre and post TAVR and whether they can predict the need for PPM null Methods null This was a prospective single center study in patients undergoing TAVR. Patients received an ECG-patch for 2 weeks pre, immediately p...
ABSTRACT null null Background null Pathogenic/likely pathogenic (P/LP) variants in the KCNQ1-encoded Kv7.1 potassium channel cause type 1 long QT syndrome (LQT1). Despite the revamped 2015 American College of Medical Genetics (ACMG) variant interpretation guidelines, the burden of KCNQ1 variants of uncertain significance (VUS) in patients with LQTS remains ∼30%. null null null Objective null To determine whether a phenotype-enhanced (PE) variant classification approach could reduce the VUS burde...
Abstract null null null BACKGROUND null Refractory epilepsy confers a considerable lifetime risk of sudden unexplained death (SUDEP). Mechanisms may overlap with sudden cardiac death (SCD), particularly regarding QTc prolongation. Guidelines in the US do not mandate the use of ECG in diagnostic evaluation of seizures or epilepsy. null null null OBJECTIVE null We aimed to determine the frequency of ECG use, QT prolongation and whether it predicts mortality in patients with seizures. null null nul...

Abstract null null Background null Pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (AF) is associated with a non-negligible long-term recurrence rate. null null null Objectives null The aim of this study was to investigate whether PVI combined with six short ablation lines on the PVI circumferences (PVI+6L group) yields higher success rates than PVI alone (PVI group). null null null Methods null In this multicenter, single-blind, randomized trial, a total of 390 patients with p...
ABSTRACT null Background null Recent case reports and small studies have reported activation of the magnet-sensitive switches in cardiovascular implantable electronic devices (CIED) by the new iPhone 12 series, initiating asynchronous pacing in pacemakers and suspension of anti-tachycardia therapies in ICDs. null Objective and Methods null We performed a prospective single-center observational study to quantify the risk of magnetic field interactions of the iPhone 12 with CIEDs. A representative...
Abstract null Background null A pathogenic variant in the gene encoding phospholamban (PLN), a protein regulating calcium homeostasis of cardiomyocytes, causes PLN cardiomyopathy. It is characterized by a high arrhythmic burden and can progress into severe cardiomyopathy. Risk assessment guides ICD therapy and benefits from personalization. It is unknown whether sex-specific differences in PLN cardiomyopathy exist. null Objective null Improving accuracy of PLN cardiomyopathy diagnosis and risk a...
Abstract null null Background null Altered ventricular depolarization due to manifest accessory pathway conduction, Wolff-Parkinson-White syndrome, leads to repolarization abnormalities that persist after pathway ablation. The term T-wave memory (TWM) has been applied to these changes, as the post-ablation T-wave vector “remembers” the preexcited QRS vector. In adults, these abnormalities can be misinterpreted as ischemia leading to unnecessary interventions. To date, there have been no comprehe...
