Course and prognostic implications of QT interval and QT interval variability after primary coronary angioplasty in acute myocardial infarction.
OBJECTIVES The aim of this study was to determine the influence of early reperfusion on the course of QT interval and QT interval variability in patients undergoing primary percutaneous transluminal coronary angioplasty (PTCA) in acute myocardial infarction (AMI) and its prognostic implications on major arrhythmic events during one-year follow-up. BACKGROUND Although early coronary artery rec...
متن کاملQT-Dispersion as a potential marker in prognosis of acute myocardial infarction
Introduction: QT dispersion in a 12 lead ECG represents the heterogeneity of ventricular repolarization. The prolongation of QT-interval dispersion increases the risk of coronary heart disease, ventricular arrhythmia, and sudden cardiac death in patients with myocardial infarction. We aimed to investigate the prognostic value of QT-dispersion in patients with acute myocardial infarction. Meth...
متن کامل[QT interval dispersion analysis in acute myocardial infarction patients: coronary reperfusion effect].
OBJECTIVE To study the effect of early reperfusion of infarct-related artery on QT(DeltaQT) dispersion interval, as well as how valuable it is as a marker for coronary reperfusion and ventricular arrhythmias. METHODS One hundred and six patients with reperfusion (WR) and 48 without reperfusion (WtR) who have received thrombolytic therapy in the acute phase of infarction were studied. ECG carr...
متن کاملIsolated inferior wall ST segment depression as an early sign of acute anterior wall myocardial infarction.
BACKGROUND Reciprocal changes may accompany ST segment elevation in the ischemic territory during acute myocardial infarction (AMI). We examined the hypothesis that isolated inferior ST segment depression on admission is an early sign of anterior wall infarction. METHODS 49 patients admitted to the coronary care unit between January 1996 and June 2008 who presented with inferior ST segment de...
متن کاملUnstable QT interval dynamics precedes ventricular tachycardia onset in patients with acute myocardial infarction: a novel approach to detect instability in QT interval dynamics from clinical ECG.
BACKGROUND Instability in ventricular repolarization in the presence of premature activations (PA) plays an important role in arrhythmogenesis. However, such instability cannot be detected clinically. This study developed a methodology for detecting QT interval (QTI) dynamics instability from the ECG and explored the contribution of PA and QTI instability to ventricular tachycardia (VT) onset. ...
