WebJan 24, 2015 · Abstract: Low atrial rhythm manifests with inverted P waves in inferior leads. It may be seen in sinus venosus atrial septal defect. This ECG shows inverted P waves in inferior leads (II, III and aVF). This indicates that the atrial activation is spreading from below upwards. It is suggestive of a focus either in the low atrium or high junction. WebObjective The clinical significance of ECG abnormalities during atrial fibrillation (AF) rhythm is poorly understood. The aim of the current study was to explore the impact of inverted T wave on cardiac prognosis in patients with AF. Methods The current study enrolled 2709 patients with AF whose baseline ECG was available from a Japanese community-based …
