EKG AcquisitionQuestion 40 of 100
A technician is placing V5 on a 12-lead EKG. Which description is correct?
a.Fifth intercostal space, left midaxillary line
b.Sixth intercostal space, left anterior axillary line
c.Fourth intercostal space, left anterior axillary line
d.Left anterior axillary line, on the same horizontal level as V4
Explanation
V5 is placed at the left anterior axillary line on the same horizontal plane as V4 rather than by counting rib spaces, because the chest wall curves and the horizontal alignment keeps V4, V5, and V6 comparable. The midaxillary line at that level is V6. Counting to the sixth space or the fourth space would place the electrode too low or too high.
