Influence of age and sex on the diagnostic yield of inherited cardiac conditions in sudden arrhythmic death syndrome decedents.

Aims: Sudden arrhythmic death syndrome (SADS) refers to a sudden death, which remains unexplained despite comprehensive post-mortem examination and a toxicological screen. We aimed to investigate the impact of age and sex on the overall diagnostic yield and underlying aetiology in decedents with SADS using a combined approach of familial evaluation (FE) and molecular autopsy (MA).

Methods And Results: Consecutive referrals to a single centre for FE only, MA only or both, following a SADS death were included.

Anticipating Urgency: Predictive Factors for Early Intervention in Appendicular Perforation.

Background: Appendicular perforation is a severe complication of acute appendicitis, leading to increased morbidity and complex post-surgical outcomes. Early identification of patients at risk of perforation is crucial to improve clinical management and reduce complications. This study aims to review and summarize the predictive value of clinical, biochemical, and radiological factors in determining the likelihood of appendicular perforation.

Noninvasive assessment of hydroquinidine effect in Brugada syndrome (QUIET BrS).

Background: Hydroquinidine reduces arrhythmic events in patients with Brugada syndrome (BrS). The mechanism by which it exerts antiarrhythmic benefit and its electrophysiological effects on BrS substrate remain incompletely understood.

Objective: This study aimed to determine the effect of hydroquinidine on ventricular depolarization and repolarization in patients with BrS in vivo.

Comparison of 6-lead smartphone ECG and 12-lead ECG in athletes and a genetic heart disease population.

Background: Smartphone electrocardiograms (iECGs) are an innovative method of capturing transient arrhythmias that are occasionally experienced by athletes. This study aimed to assess the accuracy of a 6-lead iECG compared with 12-lead ECG in athletes and those with known genetic heart disease (positive controls).

Research Design And Methods: Each participant had a resting 12-lead ECG (supine) and a 30 s 6-lead iECG (seated) taken within 2 h.

Relative utility of portable ECG devices in capturing arrhythmias in athletes.

Introduction: Traditional monitoring of athletes with cardiac symptoms is limited due to sport-specific considerations and the intermittent nature of symptoms. Some portable electrocardiogram (ECG) devices may have more diagnostic utility than traditional monitoring. Their accuracy, advantages, and limitations should be considered when a clinician is considering the most appropriate device for investigation of an athlete's symptoms.
