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.
The normal QRS axis, like the P wave axis, points downward and to the left within a coordinate between -30 o and +90 o. This axis is said to be deviated to the left (left axis deviation or LAD) if it lies between -30 o and -90 o; and deviated to the right (right axis deviation or RAD) if it lies between +90 o and 180 o.
