About Cardiac Mapping Cardiac Arrhythmia

What is the CardioInsight Noninvasive 3D Mapping System?

The CardioInsight™ Noninvasive 3D Mapping System works to capture a detailed, 3-D map of a cardiac arrhythmia. Before CardioInsight, heart rhythm information was collected by a noninvasive surface electrocardiogram (ECG) or by an invasive catheter mapping procedure2.

Other Mapping Options


To collect heart rhythm information via an ECG, sensors are placed on the chest where they record the heart's electrical activity1


This method gives a highly detailed map of the location of the rhythm disorder but requires the patient to undergo a heart catheterisation procedure under light sedation. During the procedure, a small incision is made in the groin area, and a catheter is advanced through a blood vessel to the heart.2

What are the benefits of the CardioInsight System?

The mapping system
  • The CardioInsight system does not require surgery2.
  • The vest has 252 electrodes and provides more detailed rhythm information than a standard 12-lead ECG2.
  • This heart rhythm information collected may help the physician plan and evaluate potential treatment.


The CardioInsight system can be used in a non-invasive diagnostic procedure. Potential risks of the entire procedure should be adequately considered for each patient which include radiation exposure and time required for signal collection.

What happens during a CardioInsight procedure?

1. Hospital personnel will apply the CardioInsight™ Mapping Vest to the chest. The vest is used with the CardioInsight™ Workstation to record the heart’s electrical activity.
Watch the animation below to see how the CardioInsight vest is applied. 

*This is one clinician's experience. Results may vary.

2. A CT scan of the upper body will be provided while wearing the vest. The heart’s electrical activity may be recorded either before or after the CT scan.

3. When the recording is complete, the physician will combine the information collected by the vest and by the CT scan to create 3-D maps of the heart’s electrical activity.

4. Once the heart maps are generated by the system, the physician will analyse the maps.
