How To Measure Ekg Strips. The first line should be near the left hand side of the paper containing the ecg trace. How many seconds is an ekg strip. There are 5 small boxes in a large box 0 04 x 5 0 20 seconds. A favorite ekg interpretation resource is ecg interpretation made incredibly easy.
To determine the number of ventricular contraction multiply the number of r waves in the 6 second ekg strip by 10. We would know that an ekg result has a 6 second strip when there are 3 lines on the top present in the strip. Steps on how to measure the qrs complex. A normal qrs complex measures 0 06 to 0 12 seconds which is 1 5 to 3 small boxes on the ekg strip. Find the qrs on the ekg strip. How many seconds is an ekg strip.
When you measure the qrs complex you start by measuring at the end of the pr interval to the end of s wave.
The first line should be near the left hand side of the paper containing the ecg trace. That would provide a result of the heart rate. The second line should be exactly 30 large squares subsequent to the first line. Draw two lines on the ecg trace. Most ekg strips are 6 seconds the graph paper has a marking on the top or bottom to indicate every 3 seconds. Remember each box represents 0 04 seconds.
