QT-INTERVAL MEASUREMENT IN THE ELECTROCARDIOGRAM |
摘要 |
<p>A method and apparatus for measuring the QT interval of an electrocardiogram (ECG) signal wherein the end of then T wave is identified from ECG data (1-6), the end of the T wave defined as the first time of intersection (24) at which an upright T wave of a first set of derived ECG signal data intersects an inverted T wave of a second set of derived ECG signal data, and the intersection of the two sets of ECG data is along an isoelectric line within the trough after the positive T wave peak when the superimposed isoelectric baselines from the upright and inverted ECG signals demonstrate the best least squares fit.</p> |
