Question

3. Renee is performing an ECG on a patient. She notices many of the leads have jagged peaks with irregu-

lar heights and spacing. What is occurring and how should she correct the problem?

Answer 1

Atrial fibrillation is occurring, leading to an irregular heartbeat and an increased frequency between the QRS complexes, affecting the heart rate or pulse. To correct the problem, Renee should inform the patient's healthcare provider for further evaluation and treatment, which may involve medication or procedures.

Step-by-step explanation:

In this case, the irregular heights and spacing of the jagged peaks in the ECG leads indicate atrial fibrillation, which is an abnormal heart rhythm characterized by chaotic electrical signals in the atria. This condition can lead to an increased frequency between the QRS complexes. As a result, the irregular heartbeat affects the heart rate or pulse.

To correct the problem, Renee should inform the patient's healthcare provider about the abnormal findings and recommend further evaluation and treatment. A cardiologist may suggest medications to control the heart rhythm or procedures like cardioversion or ablation to restore a normal sinus rhythm.

Answer 2

The jagged peaks with irregular heights and spacing on multiple leads of an ECG are typically indicative of artifact or interference. This can be caused by a variety of factors, including muscle movement, electrical interference from other equipment, or poor electrode contact.

To correct the problem, Renee should first check the patient's skin for any oils or lotions that may be interfering with the electrode contact. She should also ensure that the electrodes are properly placed and securely attached to the patient's skin. If the problem persists, Renee may need to adjust the patient's position or request that any nearby equipment be turned off to reduce interference.

If the artifact or interference is still present after these adjustments have been made, Renee may need to repeat the ECG or consult with a physician or specialist to determine the cause of the problem and appropriate corrective actions.
