How to Measure an ECG

The marked measurements on the X-

axis (Horizontal) are in 0.1 seconds.

The time span from each mark (red)

labeled as sec is 1.0 seconds.

Each mark between the sec marks

represents 0.1 seconds.

The RED line on the image to the left

would be measured as 0.5 seconds.

The marked measurements on the Y-

axis (Vertical) are in 0.25 mV.

The BLUE line on the image to the left

would be measured as 0.75 mV.

CalculationsCalculate the average 10 second heart rate for the control and each test solution.The formula is: (Column A + Column B + Column C) / 3 Record the answers in the proper spaces in column (D) of the data table

Calculate the change in heart rate for each test solution.The formula is: Column E solution – Column E control

Record the answers in the proper spaces in column (F) of the data table Calculate the average 60 second heart rate for the control and each test solution.The formula is: Column D x 6 Record the answers in the proper spaces in column (E) of the data table

Calculate the percent difference in heart rate for each test solution.The formula is: (Column E solution / Column E control) x 100

Record the answers in the proper spaces in column (G) of the data table
