Sine Language:
The electrocardiogram
sine wave in the graph.....
Diagram of electrocardiogram
math is a powerful tool that being used in every profession. For this power point, I'm going to talk about the "Sine language" in a medical equipment --- electrocardiogram
ECG recording is a voltage versus time curve. The distant of the first point to the second point is 1mm.
The relationship between sine and ECG
We can set up a function y = sin X, when X were taken 0,30,60,90,120,150,180, Y values corresponding respectively 0,0.5,0.8660,1,0.8660,0.5,0. Draw the corresponding point in the coordinate system of the sine wave can be drawn images.
The "sine" shows in the electrocardiogram is called electrocardiographic sine wave....
like the picture below.
If the central line is located, so we can determine the maximum, and minimum.
However, when X = 0, Y = 0, X = 180 when, Y = 0; if X ranging from 180 to 360 [], then we can see, just the original image contrast (the fourth quadrant). This is the sine of the images.
This is the graph of sine wave. we can say the maximum of the graph is +1, the minimum is -1.和The central line is 0, the period is around 5 or more(5.3 or 5,4). :)
Thank you for your patient
