Answer 1

Six second rule is one of the easiest rules to calculate heart rate in ECG .

#. Important things to note about the squares before calculating heart rate :-

Each large block contains 25 squares

Each small square represents 0.04 seconds of time

5 small squares equal 0.20 seconds of time

When you are trying to calculate the heart rate with the six second rule, you must count out enough LARGE squares to equal 6 seconds. Therefore, 30 large squares would equal 6 seconds.

#. Atrial Rate

Identify the p-waves

Beginning at the first p-wave start counting 30 large squares.

Then count how many p-waves are between the 30 large squares.

Take that number and multiple it by 10 and this is your heart rate.

#. Ventricular Rate

Identify the r-waves

Beginning at the first r-wave start counting 30 large squares.

Then count how many r-waves are between the 30 large squares.

Take that number and multiple it by 10 and this is your heart rate.
