Vectorcardiography

What is Vectorcardiography?

Both the electrocardiogram and vectorcardiogram record the electrical forces produced by the heart. They differ only in the methods by which these forces are displayed. The vectorcardiogram records the projection of the electromotive forces of the heart on a plane of the body.

Why is Vectorcardiography done?

To integrate, schematize and present three-dimensionally the information contained in the various leads to increase the accuracy and promote better understanding of the ECG.

What preparation is needed?

• This test must be ordered by a doctor.
• No restrictions on food, liquid or medications prior to the test.
• Do not apply lotions, oils, or powder to the chest area.

  How is the test done?

• It will take 15 minutes to have the monitor put on.
• The electrodes are attached as follows:
  • RA – just below the right clavicle on the midline
  • LA – just below the left clavicle on the midline
  • RL – right pelvis
  • LL – left pelvis
  • A1 – H – on either side of the neck or anywhere above the shoulder
  • A2 – E – midsternum
  • A3 – I – right mid axillary line ( same level as V6)
  • A4 – M – center of the back ( opposite E)
  • Chest electrode placement
• The test will then be interpreted by a cardiologist with training on vectorcardiography.
