Final answer:
If there is no pulse or apex beat associated with the complexes, it indicates a slow heart rate or bradycardia.
Step-by-step explanation:
If there is no pulse or apex beat associated with the complexes, it indicates a lack of normal electrical activity in the heart. In such a case, the heart rate will be affected. The absence of a pulse suggests a slow heart rate or bradycardia. This means that the heart is beating at a lower rate than normal, which can result in inadequate blood flow to vital tissues.
