BACKGROUND
An rSr' pattern in leads V1-V2 can be observed when ECG leads are placed in the 2nd intercostal space. Recently, three criteria analyzing the ST segment and r' width to identify true Brugada pattern ECGs have been described.
OBJECTIVES
To assess the feasibility and reliability of using high precordial lead ECGs in conjunction with three new criteria for identifying true Brugada pattern ECGs.
METHODS
ECGs of 491 college athletes and 181 non-athletes were performed with standard and high-lead ECGs. ECGs were then analyzed using the newly proposed criteria.
RESULTS
Zero patients had a Brugada type 1 or 2 pattern at baseline; 76 patients demonstrated an rSr' pattern in leads V1-V2 on the high-lead ECG. Two of the 76 (3%) met criteria suggesting a true Brugada ECG.
CONCLUSION
New ECG criteria based on the r' wave accurately identify rSr' patterns in V1-V2 from potential Brugada type 2 patterns in patients with purposely placed high precordial leads.
背景
当心电图导联置于第二肋间时，可在V1 - V2导联观察到rSr'图形。最近，已经描述了三种分析ST段和r'波宽度以识别真正Brugada图形心电图的标准。
目的
评估使用高位胸前导联心电图结合三种新的标准来识别真正Brugada图形心电图的可行性和可靠性。
方法
对491名大学生运动员和181名非运动员进行标准和高位导联心电图检查。然后使用新提出的标准分析心电图。
结果
基线时零例患者有Brugada 1型或2型图形；76例患者在高位导联心电图的V1 - V2导联显示rSr'图形。这76例中的2例（3%）符合提示真正Brugada心电图的标准。
结论
基于r'波的新心电图标准能准确识别在故意放置高位胸前导联的患者中，V1 - V2导联潜在的Brugada 2型图形中的rSr'图形。
