Using the same placement of three-electrode pads and a little fancy math, we can get different views of the electrical activity in the heart. Known as augmented limb leads, unipolar limb leads, or just unipolar leads, an electrocardiogram can create an augmented theoretical null point in the ...
Commonly, an ECG will use six electrodes (or leads) placed across the chest, as well as one on each arm and leg. These electrodes capture the electric currents coming from the heart from different directions, which produces an ECG (referred to as a 12 lead ECG -- the 12 views are prod...

Figure 1 shows how an ordinary, non-anomalous signal (top line) is reconstructed (middle line) with relatively small errors. Figures 2, 3 and 4 show magnified views of the successive 5 second periods. Looking at the distribution of the reconstruction error in Figure 5 shows that the error ...
What gets me is the different AV blocks and looking for ischemia in an area of the heart because of a odd slope on the tracing. I really want to become proficient in this art. I know for us in the field there isn't much we can do for the higher blocks. But not recognizing them ...
Figure 20shows the combined views of all leads in the 12-lead ECG. Figure 20. The 12-lead ECG primarily records the electrical activity of the left ventricle (right ventricular electrical activity is less prominent under normal circumstances). As depicted in the figure, the left ventricle has ...
