Yield of Tilt Table Test in Diagnosing Syncope in Patients With Suspected Neurally Mediated Syncope.

Background: Syncope is a common medical condition. The reflex or neurally mediated syncope (NMS) is the most frequent type. The tilt table test (TTT) helps distinguish syncope from other common causes of complete loss of consciousness, such as epilepsy, define syncope subtypes and guide management.

Clinical and Genetic Characteristics of Arrhythmogenic Right Ventricular Cardiomyopathy Patients: A Single-Center Experience.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited progressive cardiomyopathy. We aimed to define the long-term clinical outcome and genetic characteristics of patients and family members with positive genetic tests for ARVC in a single tertiary care cardiac center in Saudi Arabia.

Methods: We enrolled 46 subjects in the study, including 23 index-patients (probands) with ARVC based on the revised 2010 ARVC Task Force Criteria (TFC) and 23 family members who underwent a genetic test for the ARVC between 2016 and 2020.

Prevalence of sleep problems and habits among children in Saudi Arabia: A cross-sectional study.

Objectives: To investigate children's sleep problems, habits, and lifestyle changes.

Methods: A cross-sectional study was carried out in Riyadh, Saudi Arabia, over a period of 2 months, from August through September 2022, with parents of children aged 2-14 years after reviewing the literature and formulating a validated Google questionnaire containing 30 questions related to sleep habits, problems, and disorders.

Association of and single-nucleotide polymorphisms with warfarin dose adjustment in Saudi patients.

Objectives: Despite its wide usage, warfarin therapy remains challenging due to its narrow therapeutic index, inter-individual response variability, and risk of bleeding. Previous reports have suggested that polymorphisms in and genes could influence warfarin therapy. Herein, we investigated whether  -1173C>T, , and gene polymorphisms are associated with warfarin dose adjustment and related bleeding events.
