Management of patient with acute lymphocytic myocarditis and congenital long QT syndrome presenting with electrical storm and incessant Torsade de Pointes: a case report.

Background: This case highlights the management of concomitant acute myocarditis and congenital long QT syndrome with electrical storm and incessant Torsade de Pointes.

Case Presentation: An 18 years-old Southeast Asian para 1 abortus 0 (P1A0) postpartum patient with cesarean section owing to severe preeclampsia, acute lymphocytic myocarditis, and prolonged QT interval owing to long QT syndrome. She has incessant Torsade de Pointes treated with beta-blocker, lidocaine, overdrive pacing with a temporary transvenous pacemaker, left cardiac sympathetic denervation per video-assisted thoracoscopic surgery, and implantable cardioverter-defibrillator implantation.

A case report of pre-implantation feasibility test for combining leadless pacemaker and subcutaneous implantable cardioverter-defibrillator in adult congenital heart disease.

Unlabelled: New cardiac implantable electronic devices (CIEDs), such as leadless pacemakers and subcutaneous implantable cardioverter defibrillators (S-ICDs), are being used in patients with adult congenital heart disease. The selection of CIEDs often requires careful consideration due to technical challenges posed by a unique heart structure. A 27-year-old man following a surgical tetralogy of Fallot (TOF) repair developed non-sustained ventricular tachycardia, sick sinus syndrome, and complete atrioventricular block.

Melatonin as a Chronobiotic and Cytoprotector in Non-communicable Diseases: More than an Antioxidant.

A circadian disruption, manifested by disturbed sleep and low-grade inflammation, is commonly seen in noncommunicable diseases (NCDs). Cardiovascular, respiratory and renal disorders, diabetes and the metabolic syndrome, cancer, and neurodegenerative diseases are among the most common NCDs prevalent in today's 24-h/7 days Society. The decline in plasma melatonin, which is a conserved phylogenetic molecule across all known aerobic creatures, is a constant feature in NCDs.

An ECG-based machine-learning approach for mortality risk assessment in a large European population.

Aims: Through a simple machine learning approach, we aimed to assess the risk of all-cause mortality after 5 years in a European population, based on electrocardiogram (ECG) parameters, age, and sex.

Methods: The study included patients between 40 and 90 years old who underwent ECG recording between January 2008 and October 2022 in the metropolitan area of Modena, Italy. Exclusion criteria established a patient cohort without severe ECG abnormalities, namely, tachyarrhythmias, bradyarrhythmias, Wolff-Parkinson-White syndrome, second- or third- degree AV block, bundle-branch blocks, more than three premature beats, poor signal quality, and presence of pacemakers and implantable cardioverter- defibrillators.

Permanent pacemaker implantation for atrioventricular block secondary to acute pancreatitis in a patient affected by panhypopituitarism.

Background: Hypopituitarism may trigger the development of acute pancreatitis (AP) through multiple mechanisms. AP may alter normal intracardiac conduction leading to an atrioventricular block. Due to the lack of similar cases, the correct timing and indication for pacemaker implantation in such a setting are unknown.

A Case of BRASH Syndrome Required Two Hospitalizations in a Short Period.

BRASH syndrome, characterized by bradycardia, renal failure, atrioventricular (AV) nodal blockade, shock, and hyperkalemia, is a recently identified syndrome typically caused by the interplay of electrolyte imbalances and medications such as beta-blockers and calcium channel blockers. This report presents the case of a 79-year-old woman with a history of epilepsy and hypertension, managed with carbamazepine, lamotrigine, and antihypertensive medications. She developed BRASH syndrome following reduced fluid intake and worsening renal function.

Introducing a Novel Pacemaker-Mediated Arrhythmia: The Pseudo-RNRVAS Arising From Atrial Capture Challenges.

Background: This study aimed to define and explain a novel form of pacemaker-mediated arrhythmia which is initiated and sustained by atrial capture loss coinciding with ventriculoatrial (VA) conduction within the postventricular atrial refractory period (PVARP). Unlike repetitive nonreentrant VA synchrony (RNRVAS), in the pseudo-RNRVAS, the atrium is not stimulated due to pacing below the threshold level, rather than because of refractory atrial myocardium.

Objective: The objective was to elucidate the mechanisms of this pseudo-RNRVAS, identify predisposing factors, and propose preventive strategies.
