Final answer:
First, check the electrode placement and skin contact when an EKG does not conduct signals properly; if unresolved, consider other measures such as applying conductive gel or replacing electrodes.
Step-by-step explanation:
When electrodes do not conduct the signal after two EKG tracings on an electrocardiogram (ECG), the recommended course of action is to check electrode placement and skin contact first. If electrodes are not properly adhered or positioned, they may not pick up the heart's electrical signals effectively.
The standard placement of ECG leads in a 12-lead ECG involves six electrodes on the chest and four electrodes on the limbs, which must be accurately placed for optimal signal conduction.
Should this not resolve the issue, other steps may include applying conductive gel or replacing the electrodes. Ignoring the issue is not advisable, as accurate monitoring is critical for diagnosing heart function.
