    CardioInsight™ cardiac mapping system

    Noninvasive 3-D mapping solution

    Gain a new perspective on infrequent or unstable rhythms using the CardioInsight™ (CIT) solution. By noninvasively collecting body surface electrical data using a disposable, multi-electrode vest combined with a standard CT scan, the CIT solution creates 3-D, multi-chamber maps at any time throughout the patient care pathway with as little as one heartbeat.
