In this issue of the Annals, ISHNE members Professors Bayes de Luna and Bacharova substantially contribute to our understanding of atrial pathology as revealed in the electrocardiographic P wave. In so doing, the extend the work that Professor Bayes de Luna began nearly 40 years ago.

In this remarkable paper, they taxonomize the three patterns of typical advanced inter-atrial block (A-IAB), as well as describe atypical patterns (i.e. with P wave durations less than 120 ms but positive–negative polarity in the inferior leads), explain the differentiation between A-IAB and atrial enlargement, and make the case that A-IAB may be as important a predictor of future stroke as atrial fibrillation.

For those unfamiliar with the phenomenon that has been dubbed “Bayes Syndrome” (the Professor modestly avoids this eponym), this paper is the perfect introduction.

In other important developments at Annals, we have added two important individuals to our masthead.

Professor Linda Johnson, MD, PhD Associate Professor, Cardiovascular Epidemiology, Lund University has joined us in the role of Associate Editor. Her work combines a profound understanding of cardiovascular epidemiology with an interest in ambulatory ECG monitoring for assessment of atrial fibrillation risk and autonomic dysfunction. I am very grateful that she has accepted our invitation and look to encourage submissions in her areas of expertise.

In a first for the Annals, we welcome our new Social Media Editor, Andrés Felipe Miranda-Arboleda, MD. Andres hails from Medellín, Colombia, but is currently finishing his electrophysiology fellowship at Queen's University, Kingston, Ontario. Please be sure to look out for his posts on Twitter, WeChat, and other platforms to keep you informed about important new Annals publications as well as throw-backs to classic papers that have stood the test of time.

Welcome aboard, Linda and Andres!

在本期年鉴中，ISHNE 成员 Bayes de Luna 教授和 Bacharova 教授为我们理解心电图 P 波中揭示的心房病理学做出了重大贡献。通过这样做，Bayes de Luna 教授近 40 年前开始的工作得以扩展。

在这篇非凡的论文中，他们对典型晚期心房传导阻滞 (A-IAB) 的三种模式进行了分类，并描述了非典型模式（即 P 波持续时间小于 120 毫秒，但劣质导联中的正负极性），解释 A-IAB 和心房扩大之间的区别，并证明 A-IAB 可能与心房颤动一样重要地预测未来中风。

对于那些不熟悉被称为“贝叶斯综合症”（教授谦虚地避免使用这个同名词）的现象的人来说，这篇论文是一个完美的介绍。

在 Annals 的其他重要发展中，我们在刊头增加了两个重要人物。

Linda Johnson 教授，医学博士，博士，隆德大学心血管流行病学副教授加入我们担任副主编。她的工作结合了对心血管流行病学的深刻理解以及对用于评估心房颤动风险和自主神经功能障碍的动态心电图监测的兴趣。我非常感谢她接受了我们的邀请，并希望鼓励在她的专业领域提交意见。

在年鉴中，我们首次欢迎我们的新社交媒体编辑 Andrés Felipe Miranda-Arboleda，医学博士。Andres 来自哥伦比亚麦德林，但目前正在安大略省金斯敦的皇后大学完成电生理学研究。请务必留意他在 Twitter、微信和其他平台上的帖子，让您了解重要的新 Annals 出版物以及经得起时间考验的经典论文的回顾。

欢迎上船，琳达和安德烈斯！
