BACKGROUND
It has been reported that recording electrocardiograms (ECGs) in the 3rd intercostal space (ICS) is one method that can be used for detecting Brugada syndrome; however, the prevalence of Brugada-type ECGs recorded in the 3rd ICS and the usefulness of recording the ECG in the 3rd ICS in accordance with recently established electrocardiographic criteria is unknown.
METHODS AND RESULTS
ECGs were recorded in both the 4th and 3rd ICS in 17 Brugada-type ECG patients (group A) and in 206 consecutive male subjects (group B). Brugada-type ECGs were divided into 3 types. In group A, the prevalence of type 1 ECG, which is a coved-type ECG with ST-segment elevation of >/=2 mm, increased from 23.5% to 64.7% when ECG was recorded in the 3rd ICS. The conversion to type 1 ECG was found to be related to induction of ventricular arrhythmia. In group B, the prevalence of Brugada-type ECG increased from 1.5% to 5.8% when the ECG was recorded in the 3rd ICS.
CONCLUSIONS
Recording the ECG in the 3rd ICS is useful for identifying high-risk patients with Brugada-type ECG and for detecting concealed Brugada-type ECG.
背景
据报道，在第三肋间间隙（ICS）记录心电图（ECG）是可用于检测布加综合征的一种方法；然而，在第三肋间间隙记录到的布加综合征型心电图的发生率以及根据最近确立的心电图标准在第三肋间间隙记录心电图的实用性尚不清楚。
方法与结果
对17例布加综合征型心电图患者（A组）和206例连续入选的男性受试者（B组）在第四和第三肋间间隙均记录了心电图。布加综合征型心电图分为3型。在A组中，当在第三肋间间隙记录心电图时，1型心电图（即ST段抬高≥2mm的穹窿型心电图）的发生率从23.5%增至64.7%。发现转为1型心电图与室性心律失常的诱发有关。在B组中，当在第三肋间间隙记录心电图时，布加综合征型心电图的发生率从1.5%增至5.8%。
结论
在第三肋间间隙记录心电图有助于识别布加综合征型心电图的高危患者以及检测隐匿性布加综合征型心电图。
