New electrocardiographic aspects of the P wave: Its value in clinical cardiology

Abstract

Abstract In this article, we will comment on new aspects of P‐wave morphology that help us to better diagnose atrial blocks and atrial enlargement, and their clinical implications. These include: (1) Atypical ECG patterns of advanced interatrial block; (2) The ECG diagnosis of left atrial enlargement versus interatrial block; (3) Atrial fibrillation and advanced interatrial block: The two sides of the same coin; and (4) P‐wave parameters: Clinical implications.
