Answer to Question 1

F
The ECG is a graphic display of the heart's electrical activity. The ECG can provide information about the orientation of the heart in the chest, conduction disturbances, the electrical effects of medications and electrolytes, the mass of cardiac muscle, and the presence of ischemic damage. The ECG does not provide information about the mechanical (contractile) condition of the myocardium. To evaluate the effectiveness of the heart's mechanical activity, the patient's pulse and blood pressure are assessed.

Answer to Question 2

Artifacts may be due to loose electrodes, broken wires or ECG cables, muscle tremor, patient movement, external chest compressions, or 60-cycle interference.
