Fetal Tachyarrhythmia - Part I: Diagnosis [PDF]

open access: yes, 2004
Fetal tachycardia, first recognized in 1930 by Hyman et al1, is a condition occurring in approximately 0.4-0.6% of all pregnancies2. A subset of these cases with more sustained periods of tachycardia is clinically relevant.

An analysis of the use of graphics for information retrieval [PDF]

open access: yes, 1995
Several research groups have addressed the problem of retrieving vector graphics. This work has, however, focused either on domain-dependent areas or was based on very simple graphics languages.

Cardiomyopathy With Preexcitation and Conduction Abnormalities in a Child

open access: yesJournal of Arrhythmia, Volume 41, Issue 5, October 2025.
An 11‐year‐old boy presented with dilated cardiomyopathy in association with a fasciculoventricular pathway and sinus node and atrioventricular conduction abnormalities. Whole exome sequencing revealed a novel variant of uncertain significance in LIM domain‐binding protein 3 (LDB3) which has not been heretofore described.

Changes in standard of candidates taking the MRCP(UK) Part 1 examination, 1985 to 2002: Analysis of marker questions [PDF]

open access: yes, 2005
The maintenance of standards is a problem for postgraduate medical examinations, particularly if they use norm-referencing as the sole method of standard setting. In each of its diets, the MRCP(UK) Part 1 Examination includes a number of marker questions,

Heritability and causality of QRS duration and chronic heart failure risk

open access: yesESC Heart Failure, Volume 12, Issue 4, Page 3018-3027, August 2025.
Methodological framework used to investigate the heritability using linkage disequilibrium score regression (LDSC) and causal relationship between QRS duration (exposure) and chronic heart failure (outcome) using Mendelian randomization. QRS data were sourced from GWAS and exome‐wide association studies (EWAS), and chronic heart failure GWAS data were ...

Polyphenol‐Based Nutritional Strategies Combined With Exercise for Brain Function and Glioma Control: Focus on Epigenetic Modifications, Cognitive Function, Learning and Memory Processes

open access: yesFood Science &Nutrition, Volume 13, Issue 8, August 2025.
The integration of polyphenol‐based nutritional strategies with structured exercise interventions presents a promising approach to control glioma progression. By targeting neuroinflammation and cellular plasticity, this combination offers a powerful dual‐targeting strategy.

Extra‐cardiac vagal stimulation: Clinical utility of a novel diagnostic and therapeutic tool in supraventricular tachycardia

open access: yesJournal of Arrhythmia, Volume 41, Issue 4, August 2025.
Extracardiac vagal stimulation (ECVS) is a novel, safe tool inducing controlled AV/VA block. It assists SVT differential diagnosis, pathway unmasking, and ablation endpoint confirmation, adding value to EP procedures for supraventricular tachycardias.
