Sensor vest reveals irregular heart rhythms

Patients with cardiac arrhythmia can be treated more accurately and faster if the irregular heart rhythms are mapped before surgery using a sensor vest with 252 electrodes.

CardioInsight VestThis gives the cardiologist a good picture of the area to be treated beforehand which saves the cardiologist from having to locate the arrhythmia during surgery. Erasmus MC is the first Dutch hospital to use the so-called CardioInsight vest.

Cardiac movements
Last week, the third patient at Erasmus MC was diagnosed with cardiac arrhythmia using a new method, in which the patient wears a sensor vest that is connected to a system that maps irregular heart rhythms using a 3D card system. 252 electrodes record cardiac movements from outside the patient's body. A conventional ECG uses 12 electrodes. This new method is much less burdensome for patients than the current invasive method.

The system can be used to map a wide range of irregular heart rhythms in the upper and lower chambers of the heart, and creates 3D cardiac maps. The sensor vest worn by the patient pairs body surface electrical data with heart-torso anatomy. The technology collects ECG signals from the chest and combines these signals with data from a CT scan of the heart. The 3D cardiac maps treated show a detailed image of the heart rhythms.

Dr. Tamas Szili-Torok, cardiologist and electrophysiologist at Erasmus MC, is enthusiastic about the new method. Szili-Torok says "This enables us to clearly locate the arrhythmia before a surgical procedure such as ablation, and means that we can work 30% to 40% faster."
