The P-wave morphology: what does it tell us?
P-wave morphology and duration reveals several aspects of the atria: Proper function, fibrosis, dyssynchrony, and activation paths can be inferred from the surface P-wave analysis. Surface electrocardiogram (ECG) can help differentiating enlargements of the atria from conduction defects including intra- and interatrial block.The purpose of this paper is to review normal atrial morphology and the most relevant abnormal patterns.
