Hello,
1. You measure in the distance in mm from from one R wave to the next R wave.
2. Then multiply that number by 0.04 (at a normal chart speed of 25mm/sec each mm = 0.04 sec). Answer = R-R interval in seconds.
3. Divide 60 by the answer to 2. (60 seconds in a minute)
Answer = HR in bpm
Hope this helps :)
Hi,
So the above method is fine if the rate is regular (though I prefer to divide the 300 by the R-R interval), but to determine the rate in atrial fibrillation:
1. Count out 6 seconds (ie 30 big squares)
2. Count the number or QRS complexes in that period
3. Times the number of QRS complexes by 10.

What is the difference between heart rate and ventricular rate?
On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
Is there a heart rate calculator for running?
I think what you are looking for is a heart rate MONITOR. You calculate what your target heart rate should be using a formula then the monitor helps you keep track of your heart rate.
