Measurement of the QT interval.
Ventricular repolarization is reflected by the T-wave of the surface electrocardiogram, the QT interval being the time taken for ventricular recovery. QT measurement has assumed clinical importance as prolongation is associated with a variety of conditions includingthe Romano-Ward' and JervellLange-Neilson syndromes, drug toxirity' and an adverse prognosis following acute myocardial infarction....
متن کاملIssues in QT interval measurement
The QT interval, apart from clinical implications is crucial for safety assessment of new drugs under development. A QTc prolongation of even 10 msec in a study group is a warning signal for a new drug. There are various issues involved in the measurement of the QT interval especially regarding the ending of the T wave and different morphological pattern of T-U complex. The other issue is signi...
متن کاملMore light on QT interval measurement.
Aprolonged QT interval signifies a delay in the ventricular repolarisation phase, which renders the heart vulnerable to malignant arrhythmias such as torsade de pointes ventricular tachycardia. This sign of disease is sometimes subtle and may avoid recognition unless meticulously sought. In this issue of Heart, Malik and colleagues draw attention to methodological difficulties in the measuremen...
متن کاملThe Measurement of the QT Interval
The evaluation of every electrocardiogram should also include an effort to interpret the QT interval to assess the risk of malignant arrhythmias and sudden death associated with an aberrant QT interval. The QT interval is measured from the beginning of the QRS complex to the end of the T-wave, and should be corrected for heart rate to enable comparison with reference values. However, the correc...
