How can i program labview to measure the cardiac vector and the mean electrical axis of a electrocardiacgraph any ideas??

[vegas1332]

I am a student working on a senior design project of a protable Electrocardiograph machine. I have most of it complete but still need to figure out how to measure and display both the mean electrical axis and cardiac vector. If you have any ideas i would they would be greatly appreciated

I never needed it done, but I guess you are tracing all of them 12 standard (limb & precordial) leads. Knowing the angles of the limb leads (II, III, aVR, aVL, aVF) with respect to DI (zero angle), as well as having measured the R wave peaks - I reckon it is a matter of pure trigonometry (arctan, etc.). BTW, what do you mean by "cardiac vector"? Is it the orientation of the myocard? What is the difference from the "axis"? The only thing I can think of is using additional V leads for the horizontal plane. Anyway I wouldn't mind continuing this discussion via email since I am interested in the matter.
