Nursing information related to the heart (cardiac).
EKG fundamentals Bipolar leads look from a positive pole toward a negative pole. The positive electrode "looks" directly at the heart from the site where it is placed. Ground electrodes do not contribute to the tracing. "Quick look" defibrillator paddles are also bipolar. Lead MCL1 — use lead I selection on monitor; positive electrode placed in 4ICS (4th intercostal space) at the RSB (right sternal border); negative electrode placed on L shoulder; ground may be placed anywhere.
