title: Automated detection of Brugada-type electrocardiogram using diagnostic criteria of the European Society of Cardiology and the American Heart Association.
abstract: The diagnostic criteria of Brugada syndrome were reported from the European Society of Cardiology (ESC) and the American Heart Association in 2002. We examined the automated detection of Brugada-type electrocardiogram (ECG) on 12-lead ECG analysis program by modifying ESC criteria and evaluated it. In ESC criteria, Brugada-type ECG was classified into 3 types of ST-segment abnormalities of V1 to V3 leads. We modified these criteria and determined automated detection criteria as follows: type 1: STj>or=0.2 mV and STj>ST1>ST2 and T<0 mV; type 2: STj>or=0.2 mV and STj>STmin>or=0.1 mV and T>0 mV and T<1.8xR' and S<or=3.0 mV; type 3: STj>or=0.2 mV and 0.1 mV>STmin>0 mV and T>0 mV and T<1.8xR' and S>or=3.0 mV; STj, ST1, and ST2 are amplitude of the ST segment (STj: J point, ST1: J point +40 milliseconds, ST2: J point +80 milliseconds). We evaluated these criteria with 97 ECGs from 27 patients, which are diagnosed as Brugada syndrome in university hospital. Brugada-type ECGs were detected correctly in 85 of total 97 ECGs (sensitivity, 88.7%, type 1: 32/32, type 2: 50/61, type 3: 4/4). As compared with 5 cardiologists interpretation of Brugada-type ECGs, computer classified incorrectly in 20 ECGs (type 1: 2, type 2: 17, type 3: 1) in 21,524 cases.
