Lead placement is fairly standard, so that is not usually an issue. (So the S-wave does not always have to distinctly appear in a given lead.) The morphology of the QRS complex depends on heart health, anatomic position of the heart (characteristic of individual thoracic anatomy), and the particular lead of the scalar EKG you are examining. Of the QRS complex, the R-wave always appears in every lead, but the entire QRS complex (as distinct individual components) does not have to appear in any given lead. So depending on the lead, various parts of those loops will appear more or less prominently as projected on it. The scalar EKG (the 12 traces of amplitude as a funciton of time in a normal full EKG record) are the projections of that loop on lines connecting the various leads, and on the augmented (derived) ‘A’ and precordial ‘V’ leads. A reconstruction of this loop from the information in the scalar EKG is known as the vector EKG, or vectorcardiogram. Para el pico plano, la funcin devuelve solo el punto con menor ndice. La primera muestra no se incluye a pesar de ser la mxima. Los picos se muestran por orden de aparicin.
