Recording the right procordial leads at higher intercostal spaces (ICS) can raise the sensitivity of the diagnosis on Brugada syndrome using ECG. However, the directive measurement of the right precordial leads at the higher ICSs is tedious and impractical. In this paper, we proposed a derivation method based on the information redundancy in the 12-lead system to study the possibility of deriving the right precordial leads at the higher ICSs from the commonly used Mason-Likar 12-lead ECGs. Through the evaluation based on the simulated Brugada-type ECGs and recorded ECGs from BS subjects, we found that the BS characteristic J wave and coved type ST elevation in the right precordial leads at the higher ICSs could be satisfyingly derived from the 12-lead ECGs. It is concluded that the derived precordial leads at the higher ICSs may serve as an assistant diagnosis tool to unmask Brugada syndrome.
在更高肋间间隙（ICS）记录右胸前导联可提高心电图对Brugada综合征诊断的敏感性。然而，在较高ICS处对右胸前导联进行定向测量既繁琐又不实用。在本文中，我们基于12导联系统中的信息冗余提出了一种推导方法，以研究从常用的Mason-Likar 12导联心电图推导较高ICS处右胸前导联的可能性。通过基于模拟Brugada型心电图和Brugada综合征（BS）患者记录的心电图进行评估，我们发现较高ICS处右胸前导联的BS特征性J波和穹隆型ST段抬高可以从12导联心电图中得到令人满意的推导。得出的结论是，较高ICS处推导的胸前导联可作为揭示Brugada综合征的辅助诊断工具。
