QTc dispersion and complex ventricular arrhythmias in untreated newly presenting hypertensive patients

Characterisation of left ventricular function by tissue Doppler imaging technique in newly diagnosed, untreated hypertensive subjects

BACKGROUND Hypertension results in structural and functional changes in the heart. Early detection of abnormalities of cardiac structure and function is important in the assessment and treatment of hypertensive subjects. The aim of this study was to evaluate the utility of the tissue Doppler echocardiographic technique in characterising diastolic and systolic functions in untreated native black...

Complex ventricular arrhythmias.

prolonged dispersion of qt and qtc in thalassemia major patients

thalassemia major patients require repeated transfusions of packed cell and their lysis lead to iron deposition especially in the cardiac walls such as septum and posterior wall, so make thickening and cause cardiac disorders. in this case-control study, our object was to appoint if qt and qtc and te dispersions were predictors of cardiac disorders in thalassemia major patients or not. 34 thala...

Dispersion of ventricular repolarisation: a marker of ventricular arrhythmias in patients with previous myocardial infarction.

OBJECTIVE To examine whether, in coronary patients after myocardial infarction, the dispersion of ventricular repolarisation measured through QT and JT intervals from a surface electrocardiogram could allow separation of those with ventricular tachyarrhythmias (VT) complicating their myocardial infarct from those without. DESIGN A retrospective comparative study. SETTING University hospital...

Varicella myocarditis presenting with unusual ventricular arrhythmias.

A 10-year-old boy with varicella developed syncopal episodes caused by runs of self-terminating ventricular tachycardia and ventricular fibrillation. These arrhythmias were thought to be caused by varicella myocarditis and were resistant to most common antiarrhythmic agents. Continuous electrocardiographic recording and analysis proved extremely useful in the management of this case. Mexiletine...
