Related to QRS interval: QT interval. the duration of the QRS complex in the electrocardiogram. In the electrocardiogram, the interval that denotes depolarization of the ventricles, between the beginning of the Q wave and the end of the S wave. Its normal duration is 120â200 msec. Shorter durations are found, e.g., in preexcitation. Longer durations are indicative of first-degree heart block.
Presence of a short PR interval (<120 ms) A wide QRS complex longer than 120 ms with a slurred onset of the QRS waveform, termed a delta wave, in the early part of QRS. Secondary ST-T wave changes (see the image below) Classic Wolff-Parkinson-White electrocardiogram with short PR, QRS >120 ms, and delta wave.
