WebFeb 1, 2024 · 4. Divide the number 300 by your answer above. Once you have calculated the number of big squares separating QRS complexes (let's use 3.2 as an example), perform the following calculation to determine heart rate: 300/3.2 = 93.75. Round your answer to the nearest whole number. WebJan 9, 2024 · Other paper speeds: 50mm/sec. Doubling the standard rate will cause the ECG to appear drawn out or wider complex than 25mm/sec paper speeds. 1mm ( small square) = 0.02 sec (20ms) 5mm ( large square) = 0.1 sec (100ms) The rhythm strip will thus comprise 5 seconds total capture compared to the standard 10 seconds.
