Smackdown...Bob has no boat
ECG leads are attached to the body while the patient lies flat on a bed
or table. Leads are attached to each extremity (4 total) and to 6
pre-defined positions on the front of the chest (Fig.121a). A small
amount of gel is applied to the skin, which allows the electrical
impulses of the heart to be more easily transmitted to the ECG leads.
The leads are attached by small suction cups, Velcro straps, or by
small adhesive patches attached loosely to the skin. The test takes
about 5 minutes and is painless. In some instances, men may require the
shaving of a small amount of chest hair to obtain optimal contact
between the leads and the skin.
12 leads may be employed for ECG using pre-defined positions on each
extremity (Fig 123b).
