1 2. 2. 2  The average duration of the QRS complex in 100 normal adults was 0.0777 second. 3  Fifty of the patients were males with an average duration of the QRS time interval of 0.0833 second, and 50 were females with a shorter time interval of 0.0722 second.
Prolonged QRS duration indicates abnormal conduction through the His-Purkinje system leading to longer period of depolarization. QT interval varies by heart rate, therefore, corrected QT interval (QTc) is used instead. A normal QTc should be less than 0.42 sec in men and less than 0.45 sec in women.he QRS axis in this ECG is 150 degrees: Heart Rhythm. A normal heart rhythm is when the origin of the impulse is from the sinus node (sinus rhythm) with normal AV conduction. Therefore, a normal heart rhythm is when the P wave axis is normal + Normal AV conduction (PR interval) + Normal heart rate for age.
