OBJECTIVE: To evaluate the preoperative prevalence of each type of J-wave syndrome electrocardiographic pattern and its association with perioperative @entity299 . DESIGN: Retrospective study. SETTING: Single hospital university study. @entity1 : The study evaluated 930 @entity1 who underwent gynecologic, abdominal, neurosurgical, orthopedic, and urologic surgeries. INTERVENTIONS: Preoperative standard 12-lead electrocardiogram (ECG) monitoring was performed, and each type of J-wave syndrome ECG pattern-types 1, 2, and 3 and Brugada syndrome-type-was evaluated. Incidence of perioperative @entity299 was investigated up to 1 year postoperatively using an electronic medical record system. MEASUREMENTS AND MAIN RESULTS: Data from 789 @entity1 were included in the final study. Of these, 16 @entity1 (2.0%) had J-wave syndrome: 7 @entity1 (0.9%) had type-1 patterns; 5 @entity1 (0.6%) had type-2 patterns; 2 @entity1 (0.3%) had type-3 patterns; and 2 @entity1 (0.3%) had @entity1789 patterns. A J-point elevation>= 0.2 mV, which is considered to be more dangerous, was found in only 2 @entity1 with @entity1789 patterns, both of whom suffered perioperative @entity943 . CONCLUSION: @entity1 with J-wave syndrome ECG patterns, even dangerous patterns, are not necessarily associated with a higher risk of perioperative @entity299 . However, @entity1789 patterns should be carefully monitored.
