About Cardiac Mapping Cardiac Arrhythmia

What is the CardioInsight Noninvasive 3D Mapping System?

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

Other Mapping Options

EKG

To collect heart rhythm information via an EKG, sensors are placed on your chest where they record your heart's electrical activity. While helpful, this method does not provide much detail about the specific location of the rhythm disorder.1

INVASIVE CATHETER MAPPING

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


What are the benefits of the CardioInsight System?

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

What cardiac arrhythmias can be mapped with the CardioInsight System?

NOTE: Not all cardiac arrhythmia conditions can be identified by your physician using the maps created by the CardioInsight Noninvasive 3D Mapping System.


What happens during a CardioInsight procedure?

1. Hospital personnel will apply the CardioInsight™ Mapping Vest to your chest. The vest is  used with the CardioInsight™ Workstation to record your heart’s electrical activity.
 
Watch the animation below to see how the CardioInsight vest is applied. 
 
2. You will get a CT scan of your upper body while wearing the vest. Your heart’s electrical activity may be recorded either before or after the CT scan. 

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

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