Effect of Balloon Inflation-Induced Acute Ischemia on Qt Dispersion During Percutaneous Transluminal Coronary Angioplasty
(Clinical Cardiology Publ Co, 1999)
Background: QT dispersion (QTd = QT(max) - QT(min)) measured as interlead variability of QT interval reflects the spatial inhomogeneity of ventricular repolarization times, and increased QTd may provide a substrate for ...
Qt Dispersion Plus St-Segment Depression: A New Predictor of Restenosis After Successful Percutaneous Transluminal Coronary Angioplasty
(Clinical Cardiology Publ Co, 1999)
Background: ST-segment depression during exercise testing is frequently observed in the absence of restenosis after percutaneous transluminal coronary angioplasty (PTCA). Hypothesis: With the goal of improving the prediction ...
