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 ...
Introduction Organophosphate (OP) compounds are commonly used as suicidal agents and produce characteristic toxic effects. Cardiac arrhythmias are often observed in the acute phase of toxicity; late onset polymorphic ventricular tachycardia preceded by prolonged QT interval on the EKG is also known to oc...
Cardiac arrhythmias are often observed in the acute phase of toxicity; late onset polymorphic ventricular tachycardia preceded by prolonged QT interval on the EKG is also known to occur. However, there are no reports of late onset, prolonged asystole without preceding arrhythmias and after acute ...
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...
