electrocardiogram Electrocardiogram Lab Introduction Electrocardiograms atomic event 18 apply to obtain information about the lam of the center field. An ECG is a enter of the electrical application of the heart made from electrodes situated on the surface of the skin. Salt solutions argon good conductors of electricity and can transfer electrical activity to the skins surface. An ECG trace shows the sum of the electrical potentials generated by all in all the cells of the heart at any moment (Silverthorn, 1998). Each take reflects depolarisation or repolarization of a portion of the heart. Depolarization is the orient for contraction.
There are three major components of an ECG: the p waves, which corresponds to depolarization of the atria (Silverthorn, 1998). The qrs thickening represents the progressive wave of ventricular depolarization (Silverthorn, 1998). And the t wave, represents the repolarization of the ventricles. When recording an ECG, one active surface electrode is the positi...If you necessitate to get a full essay, order it on our website:
