Andersen-Tawil Syndrome with High Risk of Sudden Cardiac Death in Four Mexican Patients. Cardiac and Extra-Cardiac Phenotypes

Recurrent syncope in the Andersen Tawil syndrome - Cardiac or neurological?

An 8-year-old female patient was referred to a paediatrician for assessment of an episode of global muscle weakness after a 100 m sprint. There was no loss of consciousness. Proximal hip muscles and shoulder girdle weakness was noted and the possibility of a myopathy was raised. Muscle biopsy demonstrated “ultra-structurally normal muscle fibres”. There was indolent progression of proximal musc...

Risk of sudden cardiac death

BACKGROUND The aim of this study was to determine characteristics of patients with sudden cardiac arrest (SCA) and/or sudden cardiac death (SCD). We need an effective risk stratification method for SCD in patients without low left ventricular ejection fraction (LVEF). METHODS The study population of this cross-sectional study consisted of 241 patients with SCA or SCD who were admitted to an a...

Sudden cardiac death risk stratification.

Arrhythmic sudden cardiac death (SCD) may be caused by ventricular tachycardia/fibrillation or pulseless electric activity/asystole. Effective risk stratification to identify patients at risk of arrhythmic SCD is essential for targeting our healthcare and research resources to tackle this important public health issue. Although our understanding of SCD because of pulseless electric activity/asy...
