Methods On presentation, we measured the QTc dispersion of the ECG and Glasgow Coma Scale (GCS) of patients. The QTc dispersion is the difference in the QT duration of the longest minus the shortest rate-corrected QT interval. Computer tomography of the brain was performed in order to ...
Prolonged QTc (Corrected QT interval) on electrocardiogram (EKG) is an established marker for higher risk of sudden cardiac death. There are limited data on the prevalence of prolonged QTc in SCD patients. Aim: We studied the prevalence, EKG and echocardiographic characteristics correlated with ...
OBJECTIVE: We sought to determine whether ganglionic (α3) acetylcholine receptor autoantibodies (α3-AChR-Ab) are associated with QT prolongation. BACKGROUND: Our hypothesis was prompted by a seropositive patient with acquired long QT syndrome who presented with ventricular fibrillation and was ...
To assess repolarization lability in the surface electrocardiogram, we developed an automated algorithm, based on template matching, to measure beat-to-beat changes in QT interval. We calculate a QT variability index...doi:10.1016/S0735-1097(03)81046-XKhurram Nasir...
EKGHIVQT interval.Objective: Abnormal ECGs are associated with increased risk of arrhythmias and sudden cardiac death. We aimed to investigate the prevalence and associated risk factors of prolonged QTc and major ECG abnormalities, in persons living with HIV (PLWH) and uninfected controls.Design: ...
