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.
- 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? - 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? - 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?
