Inappropriate therapy due to noise oversensing caused a true ventricular fibrillation (VF) and a life-threatening event in a patient. A 19-year-old patient with surgically corrected congenital heart disease and systolic dysfunction had an implantable cardioverter defibrillator implanted for primary prevention in 2013. This patient was admitted at the Emergency Department in June 2018 after receiving eight shocks from the device on the same day, with a prolonged syncope after the third shock. Another noise-induced VF detection occurred, and two inappropriate shocks followed sequentially, causing true VF. Four appropriate shocks were subsequently needed until sinus rhythm was finally restored.

Dimensional structure of the Brief Illness Perception Questionnaire and Association with adverse childhood experiences in patients with an implantable cardioverter-defibrillator.
Sci Rep

Department of Consultation-Liaison-Psychiatry and Psychosomatic Medicine, University Hospital Zurich, University of Zurich, 8091, Zurich, Switzerland.
Illness perceptions (IP), as measured by the Brief Illness Perception Questionnaire (BIPQ), and adverse childhood experiences (ACE) have been shown to affect the physical and psychological well-being in different patient populations. However, little is known about IP and ACE in patients with an implantable cardioverter-defibrillator (ICD). Our objectives were to investigate the dimensional structure and to evaluate correlates of the BIPQ in ICD patients.

Introduction: The role of the sympathetic nervous system in the initiation and continuation of ventricular tachyarrhythmias (VTA) is well established. However, whether CSD reduces implantable cardioverter-defibrillator (ICD) shocks and recurrent VTA is still uncertain.
Methods: A comprehensive literature search was performed at Medline and Embase until March 2023.
Interrupted versus uninterrupted anticoagulation for cardiac rhythm management device insertion.

Department of Pharmacy Practice, University of Connecticut, Storrs, CT 06269, USA.
Background: Guideline-recommended strategies to interrupt chronic anticoagulation with warfarin or direct oral anticoagulants (DOAC) during the perioperative period of cardiac implantable electronic device (CIED) surgery differ worldwide. There is uncertainty concerning the benefits and harms of interrupted and uninterrupted anticoagulation in patients undergoing CIED surgery.
Objectives: To assess the benefits and harms of interrupted anticoagulation (IAC) with either warfarin or DOAC in the perioperative period of CIED surgery versus uninterrupted anticoagulation (UAC), with or without heparin bridging, during an equivalent time frame, for CIED surgery.
Implementation of a Sudden Cardiac Death Risk Prediction Tool in Clinical Practice Through Electronic Health Records (INSERT-HCM Study Design).

Sudden cardiac death is a leading cause of mortality in children with hypertrophic cardiomyopathy (HCM). The PRecIsion Medicine in CardiomYopathy consortium developed a validated tool (PRIMaCY) for sudden cardiac death risk prediction to help with implantable cardioverter defibrillator shared decision-making, as recommended by clinical practice guidelines. The mplemeting a udden Cardiac Dath isk Assessment ool in hildhood (INSERT-HCM) study aims to implement PRIMaCY into electronic health records (EHRs) and assess implementation determinants and outcomes.

Background: The evidence in the primary prevention of sudden cardiac death (SCD) by using implantable cardioverter defibrillators (ICD) in patients with ischemic cardiomyopathy (ICM) is well-established but remains controversial for those with nonischemic cardiomyopathy (NICM). This study evaluates whether prognostic differences exist between ICM and NICM patients after ICD implantation.
Methods: Patients initially undergoing ICD implantation as primary SCD prevention were retrospectively enrolled from January 2017 to May 2023.
