Despite their proven efficacy at reducing mortality in selected patients, implantable cardioverter-defibrillators have some proarrhythmic effects. In this report, we present a case of a patient with recurrent ventricular tachycardia degeneration to ventricular fibrillation by appropriate low-energy implantable cardioverter-defibrillator shocks.

Objective: Hypercalcemia is often considered as an emergency because of a potential risk life-threatening arrhythmias or coma. However, there is little evidence, apart from case studies, that hypercalcemia can be immediately life-threatening. The aim of our study was to assess prospectively, if hypercalcemia (Ca ≥ 3 mmol/L) was associated with immediately life-threatening complications.

Ryanodine receptor 2 (RyR2) protein, a calcium ion release channel in the sarcoplasmic reticulum (SR) of myocardial cells, plays a crucial role in regulating cardiac systolic and diastolic functions. Mutations in RyR2 and its dysfunction are implicated in various congenital heart diseases (CHDs). Studies have shown that mutations in the RYR2 gene, which encodes the RyR2 protein, are linked to several cardiac arrhythmias, including catecholaminergic polymorphic ventricular tachycardia (CPVT), long QT syndrome (LQTS), calcium release deficiency syndrome (CRDS), and atrial fibrillation (AF).

Background: Ventricular tachycardia ablation (VTA) is an important treatment option for ventricular tachycardia, with increasing use across all age groups. However, age-related differences in outcomes remain a concern.
Objective: This study aimed to investigate age-related trends in VTA procedures and their associated adverse events across the United States from 2011 to 2021.
