The 12-lead ECGElectrocardiogram; also called an EKG; a representation of electrical voltage measured across the chest over a period of time. 1. Six Second ECG Guidebook (2012), T Barill, p. 196 More provides 12 views of the heart. The 12 views are generated through only 10 electrodes. Four limb electrodesThe 12-lead ECG provides 12 views of the heart. The 12 views are generated through only 10 electrodes. Four limb electrodes attach to the inner forearms and calves.

The remaining 6 electrodes, labelled successively from V1 to V6, are attached to the chest to provide precordial views.
The systematic ECG interpretation of a 12 lead ECG takes a bit more time than the six seconds necessary to correctly name most single lead rhythmOften refers to a discernible pattern in time or distance between QRS complexes and/or P waves. More strips. While many excellent approaches to 12 lead interpretation exist, all methods include certain key points that are incorporated into a four-step system for 12 lead ECG analysis.
Table 6.1 details the electrode placement for the 12 lead ECG. Note that only ten electrodes are used for twelve lead viewsLocating the positive electrode is crucial to determining which area of the heart is viewed electrically. Metaphorically, the positive electrode serves as a mini-video camera aimed at the heart in the direction of the negative electrode. These leads and their... More.
