ECG vest enables non-invasive heart maps
Medtronic landed FDA clearance for its CardioInsight 3D cardiac mapping system that’s used to locate sources of arrhythmias. The system consists of an ECG vest with a whopping 252 electrodes. It’s used to collect highly detailed skin surface electric signal data while the patient is inside a CT scanner. This data is overlaid onto the resulting CT scan to create a 3D representation of the heart and its electric activity.
Cardiac mapping is normally done via a catheter, which introduces risks, costs, and discomfort. Because the CardioInsight can be used at the bedside or in a doctor’s office, it may be able to take some strain off of electrophysiology labs.
Some details from Medtronic about the system’s capabilities:
"The vest technology contours to the patient’s body and allows for continuous and simultaneous panoramic mapping of both atria or both ventricles, which cannot be achieved with current invasive methods. The 3D cardiac maps can be created by capturing a single heartbeat, and enable rapid mapping of these heart rhythms. The predecessor system has been used with more than 1,600 patients and is featured in more than 120 peer-reviewed journals and presentations".
