WebA QRS complex normally follows each P wave. Many variations exist in the configuration of the QRS complex and not every QRS complex contains a Q wave, R wave or S wave. The shape indicates what path the electrical signal took through the ventricles. Whatever the variation, it is still called the QRS complex. WebJul 9, 2024 · The normal PR interval should be between 3 to 5 small boxes wide, which is 0.12 to 0.20 seconds in duration. If the PR interval is longer than 5 small boxes, it is …

Each small box represents 0.04 seconds, so we know this wave on the EKG graph took place in 0.12 seconds. It is a good idea to get comfortable with measuring waves in this manner and calculating the time per wave, as it will help your EKG interpretation greatly. WebJun 8, 2024 · Normal duration: 0.12-2.0 seconds ( 3-5 horizontal boxes ). This is measured from the onset of the P wave to the onset of the QRS complex regardless if the initial wave is a Q or R wave. How many boxes on ECG is 6 seconds?
