Holter study of heart rate variability in children and adolescents with long QT syndrome.
Ann Noninvasive Electrocardiol
July 2024
Objectives: This study aimed to retrospectively assess cardiac autonomic activity in children with LQTS, considering genotype, symptoms, sex, age, and beta-blocker therapy (BB) and compare it to healthy controls.
Methods: Heart rate variability (HRV), using power spectrum analysis, was analyzed in 575 Holter recordings from 116 children with LQTS and in 69 healthy children. The data were categorized into four age-groups and four heart rate (HR) ranges.
Background: Swimming is a genotype-specific trigger in long QT syndrome type 1 (LQT1).
Objective: To examine the autonomic response to water activities in children and adolescents with LQT1.
Methods: In this cross-sectional study, LQT1 patients were age and sex matched to one healthy control subject.
Article Synopsis
- The study looked at different types of surgeries for patients with blocked arteries in the neck to see which was safer and better long-term.
- Researchers checked the results of over 9,000 surgeries done over a period of 11 years in Sweden.
- They found that using a simple closure method after surgery increased the chances of having a stroke, but overall, the long-term risk of strokes or death was similar no matter the surgery type or patch material used.
A range of neuroradiological findings has been reported in patients with COVID-19, some mimicking cerebral small vessel disease (CSVD). We present a case of a man in his 50s with severe COVID-19, who was Glasgow Coma Scale 3 and tetraparetic after sedation was ceased in the intensive care unit. Return of consciousness and motor activity was slow.

IL-6 signals through two pathways: classical IL-6 signalling with C-reactive protein (CRP) as a product is pivotal in the acute immune response against pathogens while IL-6 trans-signalling is involved in prolonged inflammation. We measured biomarkers of the IL-6 classical and trans-signalling pathways in patients with moderate or severe COVID-19 in the first wave of the COVID-19 pandemic.
