PR Interval as a Valuable Predictor of Tilt Table Test Results in Patients With Neurally Mediated Syncope

Annals of Noninvasive Electrocardiology, Volume 30, Issue 2, March 2025.
A longer PR interval correlates with a positive tilt table test. This suggests that an AEM‐derived PR interval duration longer than 160 ms may be a valuable tool for predicting TTT results and identifying patients at higher risk of NMS. ABSTRACT Background Neurally mediated syncope (NMS) is the primary cause of temporary and self‐limiting loss of ...

Guidelines for the standardization of pre‐analytical variables for salivary biomarker studies in Alzheimer's disease research: An updated review and consensus of the Salivary Biomarkers for Dementia Research Working Group

Alzheimer's &Dementia, Volume 21, Issue 2, February 2025.
Abstract There is a pressing need for accessible biomarkers with high diagnostic accuracy for Alzheimer's disease (AD) diagnosis to facilitate widespread screening, particularly in underserved groups. Saliva is an emerging specimen for measuring AD biomarkers, with distinct contexts of use that could complement blood and cerebrospinal fluid and detect ...

GestaltMML: Enhancing Rare Genetic Disease Diagnosis through Multimodal Machine Learning Combining Facial Images and Clinical Texts [PDF]

arXiv, 2023
Individuals with suspected rare genetic disorders often undergo multiple clinical evaluations, imaging studies, laboratory tests and genetic tests, to find a possible answer over a prolonged period of time. Addressing this "diagnostic odyssey" thus has substantial clinical, psychosocial, and economic benefits.

Long-Term Natural History of Adult Wolff–Parkinson–White Syndrome Patients Treated With and Without Catheter Ablation

Circulation: Arrhythmia and Electrophysiology, 2015
Background—There are a paucity of data about the long-term natural history of adult Wolff–Parkinson–White syndrome (WPW) patients in regard to risk of mortality and atrial fibrillation.

Syndrome Measurement Order for the [[7,1,3]] Quantum Error Correction Code [PDF]

arXiv, 2013
In this work we explore the accuracy of quantum error correction depending of the order of the implemented syndrome measurements. CSS codes require bit-flip and phase flip-syndromes be measured separately. To comply with fault tolerant demands and to maximize accuracy this set of syndrome measurements should be repeated allowing for flexibility in the ...

Conversion of supraventricular arrhythmias to sinus rhythm using flecainide [PDF]

, 2017
We evaluated the efficacy of flecainide acetate (given intravenously to a maximal dose of2 mg kg−1 and then orally in a dose of 100 mg b.d. or 100 mg t.d.s.) in the conversion to sinus rhythm of 50 patients exhibiting supraventricular arrhythmias (39 ...

Acceleration of the Ventricular Response During Atrial Fibrillation in the Wolff‐Parkinson‐White Syndrome After Verapamil

Circulation, 1982
We examined the electrophysiologic effects of verapamil in eight patients with the Wolff-Parkinson-White syndrome. Verapamil shortened the antegrade effective refractory period of the accessory pathway in three patients and abbreviated the shortest cycle

Atrial Tachyarrhythmia in Arrhythmogenic Right Ventricular Cardiomyopathy: A Case Report

Clinical Case Reports, Volume 13, Issue 2, February 2025.
ABSTRACT Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heritable myocardial condition that mostly affects the right ventricle (RV). Atrial involvement is poorly understood and the evidence for atrial involvement remains limited. In this case report, we describe an 18‐year‐old woman who had ARVC with the atrial tachyarrhythmia and ...

Transgenic Mouse Model of Ventricular Preexcitation and Atrioventricular Reentrant Tachycardia Induced by an AMP-Activated Protein Kinase Loss-of-Function Mutation Responsible for Wolff-Parkinson-White Syndrome

Circulation, 2005
Background—We identified a gene (PRKAG2) that encodes the &ggr;-2 regulatory subunit of AMP-activated protein kinase (AMPK) with a mutation (Arg302Gln) responsible for familial Wolff-Parkinson-White (WPW) syndrome.

Pregnancy in women with mitochondrial disease—A literature review and suggested guidance for preconception and pregnancy care

Australian and New Zealand Journal of Obstetrics and Gynaecology, Volume 65, Issue 1, Page 30-36, February 2025.
Mitochondrial donation to reduce the risk of primary mitochondrial disease transmission from mother to child is now permitted under Australian law as part of a clinical trial. The energy demands of pregnancy have the potential to worsen mitochondrial disease symptoms and severity in affected women.
