Inclusion criteria
Inclusion criteria: More than 17 years old who were scheduled to surgery were investigated retrospectively. Patients for cardiac surgery or who were already diagnosed as Brugada syndrome were excluded. ER was defined as 0.1mV or more ST elevation at the J point in more than one lead of 12-lead ECG and the J wave was defined as upward deflection as slurring or notching terminal part of QRS complex. ECG patterns of J wave syndromes were classified as follows: type 1 ,an ER pattern with J waves in lateral leads(I,V4-5) which is commonly seen in healthy people,type2,an ER pattern with J waves in inferior leads (II,III,aVF) which is associated with a higher level of risk for VF, type3, an ER pattern with J waves in global leads which is associated with the highest level of risk for VF, and Brugada syndrome pattern, an ER pattern with J waves in V1-3. Perioperative cardiac incidents were examined up to 1 year after the surgery.
