Article Synopsis
- A study was conducted to assess how well two wearable ECG devices, the Apple Watch and KardiaMobile 6L, can accurately measure important heart metrics in patients with congenital long QT syndrome (LQTS).* -
- Researchers compared these wearable devices' readings to a standard 12-lead ECG in 98 patients and found that both devices offered moderate to strong correlations, especially in measuring the corrected QT interval and analyzing ST-T wave patterns.* -
- While the wearable devices showed promise as additional monitoring tools, they are not a substitute for traditional 12-lead ECG tests in managing patients with LQTS.*
Aims: The incidence of atrial tachyarrhythmias is high in patients with atrioventricular septal defect (AVSD). No specific data on catheter ablation have been reported so far in this population. We aimed to describe the main mechanisms of atrial tachyarrhythmias in patients with AVSD and to analyse outcomes after catheter ablation.

Electrophysiological studies (EPS) before pulmonary valve replacement (PVR), the most common reintervention in tetralogy of Fallot, could potentially inform therapy to improve arrhythmic outcomes.
Methods: A prospective multicenter study was conducted to systematically assess EPS with programmed ventricular stimulation in patients with tetralogy of Fallot referred for PVR from January 2020 to December 2021.
Arrhythmogenic cardiomyopathy (ACM) is a rare genetic disease associated with ventricular arrhythmias in patients. The occurrence of these arrhythmias is due to direct electrophysiological remodeling of the cardiomyocytes, namely a reduction in the action potential duration (APD) and a disturbance of Ca homeostasis. Interestingly, spironolactone (SP), a mineralocorticoid receptor antagonist, is known to block K channels and may reduce arrhythmias.

Health care system is itself a large contributor to greenhouse gas (GHG) emissions. In cardiology, atrial fibrillation (AF) catheter ablation is an increasing activity using numerous non-reusable materials that could contribute to GHG emission.

Background: Data regarding atrial arrhythmias in adults with AVSD are particularly scarce.
Methods: Data were analyzed from a multicentric cohort of adult patients with AVSD.
Background: Twin atrioventricular (AV) nodal tachycardia is a rare mechanism of supraventricular arrhythmia, only seen in some specific congenital heart defects (CHD). It consists of a re-entrant circuit between two distinct AV nodes (anterior and inferior). Since both nodes have antegrade and retrograde conduction, there is usually two QRS morphologies in sinus rhythm.

- The study evaluated the effect of pulmonary valve replacement (PVR) on the incidence of ventricular arrhythmias in tetralogy of Fallot (TOF) patients who have implantable cardioverter-defibrillators (ICDs).
- Results showed that among the 165 TOF patients monitored, those who underwent PVR experienced significantly fewer appropriate ICD therapies after the surgery compared to before, indicating a reduction in arrhythmia burden.
- The findings suggest that PVR may play a crucial role in decreasing the risk of arrhythmias and highlight the importance of considering PVR in the treatment plans for high-risk TOF patients.
Background: To gain further insights into mechanisms leading to atrial fibrillation (AF) recurrence after a first ablation procedure using cryoballoon technique, the data collected during redo procedure were analyzed.
Methods And Results: From a total of 112 patients who underwent cryoballoon pulmonary vein isolation (PVI) for paroxysmal AF, 44 had a second ablation procedure using radiofrequency catheter, because of recurrent atrial arrhythmia. PV reconduction was observed in 109 of the 171 initially isolated veins (64%).
