A great idea for a resource but unfortunately it is wrong. On the hexaxial co-ordinates, you need to plot the height of the R wave relative to the isoelectric line MINUS the height of negative-going Q or S wave relative to the isoelectric line. If you plot the total height of the QRS complex as shown here, the vector calculation will be wrong. For example, if the QRS complex in a particular lead is distributed 50% above and 50% below the isoelectric line (as happens if your cardiac vector is orthogonal to the recording axis) then your net measurement MUST be zero and the co-ordinate for that lead that you plot on the hexaxial diagram should be at its centre.

11 years later this is still useful and relevant. By the way why Lead II? In most guides they use Lead I and aVf.

" In the four-chamber view of the fetal heart, the normal axis lies at a 45 degree angle (range 22-75 degrees) to the left of an anteroposterior line drawn from the spine to the anterior chest wall." Normal fetal heart axis and position. ~Comstock CH. => i think it is absolutely normal angle :))

Can we use tha AvF lead instead of II?

This Tutorial is false. The heart axis is the result of the three vectors of lead I, lead II and lead III. You must draw the output vector of the three vectors. You must see some videos about how to sum up vectors if you don't know that already in mathematics.

we cant use rulers and stuff like that.....how else can we calculate it its sooo hard ive been trying to figure this out for so long now

so nice of you sir, thanks

thank you so much it's so interesting and that helped me a lot. But can you tell me please, why some doctors use DI and avF or avR to calculate heart axis? I don't understand how to choose?

for the patient 3 I got 27 degrees! It's way off 33 degrees on answer pack! And I Triple checked my answer. I dont know what I did wrong....

Does the measurement has to be exact? Can it be 0.1cm off?
