MSN5031 Differential Diagnosis and Collaborative Management in Acute Care

Case Study

Chapter 16: Special Diagnostic Studies

A cardiac patient is having some follow-up testing on the current condition of the heart. The

patient always researches on the Internet to get the latest information about diagnostic tests that

are performed. The patient has a few questions for the healthcare provider about the upcoming

scheduled examinations.

1. The patient is having a vectorcardiogram done. The patient does not understand the

difference between the electrocardiogram and the vectorcardiogram because both are

recording the electrical forces of the heart. What is the best explanation of a

vectorcardiogram?

2. The patient is recovering from a recent myocardial infarction. The patient is scheduled

for a signal-averaged electrocardiogram. What are the indications for this diagnostic test?

3. The patient is going to wear a Holter monitor. The patient tells the healthcare provider

this monitor will provide an electrical shock in case of a ventricular dysrhythmia. Is the

patient’s understanding correct? Why or why not?
