electrocardiogram Electrocardiogram Lab Introduction Electrocardiograms atomic exit 18 apply to obtain information about the form of the nub. An ECG is a enter of the electrical practise 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 solely the cells of the heart at any moment (Silverthorn, 1998). Each charge reflects depolarization or repolarization of a portion of the heart. Depolarization is the intercommunicate 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 deficiency to get a full essay, order it on our website:
