ABSTRACT
OBJECTIVE:
To evaluate the preoperative prevalence of each type of J-wave syndrome electrocardiographic pattern and its association with perioperative cardiac events.DESIGN:
Retrospective study.SETTING:
Single hospital university study.PARTICIPANTS:
The study evaluated 930 patients 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 cardiac events was investigated up to 1 year postoperatively using an electronic medical record system. MEASUREMENTS AND MAINRESULTS:
Data from 789 patients were included in the final study. Of these, 16 patients (2.0%) had J-wave syndrome 7 patients (0.9%) had type-1 patterns; 5 patients (0.6%) had type-2 patterns; 2 patients (0.3%) had type-3 patterns; and 2 patients (0.3%) had Brugada syndrome-type ECG patterns. A J-point elevation≥0.2 mV, which is considered to be more dangerous, was found in only 2 patients with Brugada syndrome-type ECG patterns, both of whom suffered perioperative lethal arrhythmias.CONCLUSION:
Patients with J-wave syndrome ECG patterns, even dangerous patterns, are not necessarily associated with a higher risk of perioperative cardiac events. However, Brugada syndrome type ECG patterns should be carefully monitored.Palavras-chave
