OBJECTIVE: To elucidate the relation of changes in computerized vectorcardiographic trend parameters indicating perioperative @entity741 with perioperative @entity299 . DESIGN: Prospective clinical study. SETTING: A single university hospital. @entity1 : Thirty-eight @entity1 undergoing elective abdominal aortic surgery. INTERVENTIONS: Computerized vectorcardiography recorded during surgery and for 48 hours postoperatively. MEASUREMENTS AND MAIN RESULTS: Vectorcardiographic spatial alterations in the QRS complex (QRS-VD) and absolute (ST-VM) and spatial (STC-VM) ST-segment changes, previously used indicators of @entity741 , were analyzed and related to the @entity299 detected clinically. In five @entity1 with clearly @entity63 ( @entity204 , @entity583 , recurrent @entity63 ) and eight @entity1 with possibly @entity63 ( @entity712 , @entity943 ) perioperative @entity299 , ST-VM and STC-VM were significantly increased intraoperatively. Postoperatively, these differences remained, but QRS-VD were also significantly increased. Intraoperative and postoperative changes indicating @entity63 were strongly related (r = 0.83). The signs of @entity63 were most pronounced during the postoperative 12 to 36 hours. The presence of 60 minutes of signs of @entity63 during 2 hours revealed high sensitivity (85%), specificity (80%), and positive (69%) and negative (91%) predictive values for subsequent @entity299 . Traditional vector loop analysis showed signs of non-Q-wave @entity1188 in six @entity1 , whereas only three of these were detected using standard clinical methods. CONCLUSIONS: Vectorcardiographic signs of @entity741 were significantly increased intraoperatively, but most pronounced postoperatively in the @entity1 subsequently suffering @entity299 . The changes could be related to the individual cardiac morbidity with acceptable precision. Thus, continuous vectorcardiographic monitoring may be beneficial for @entity1 at risk of developing perioperative @entity63 .
