It was reported that a patient underwent an atrial fibrillation procedure that utilized a carto 3 system and suffered a ventricular tachycardia.During the procedure, the physician noticed that the ecg surface had disappeared from the carto 3 system display.Multiple system errors were generated, some of which indicated that the system should be shut down and some linked to body surface (bs) ecg recordings.Although multiple attempts have been made to obtain clarification to this complaint, no further information has been made available.Thus, it is not clear from all follow-ups performed, how, why or when the patient suffered a ventricular tachycardia.The awareness date for this complaint was reset to (b)(4) 2014, the date we were made aware that the patient suffered a ventricular tachycardia.
