Why the study?
Early identification of increased risk for frequently asymptomatic AF episodes is essential for preventing cardioembolic events, and P-wave analysis of interatrial conduction block represents a noninvasive prediction modality.
Does extended cardiac monitoring detect occult atrial fibrillation in a patient with ischemic stroke and advanced interatrial block?
Does extended cardiac monitoring detect occult atrial fibrillation in a patient with ischemic stroke and advanced interatrial block?
Advanced interatrial block on ECG in patients with ischemic stroke should prompt extended cardiac monitoring to detect occult atrial fibrillation and guide anticoagulation therapy.
Sequential ECG monitoring detects AF in ~25% of strokes; hypothesis-generating for noninvasive predictors, prospective validation needed.
Atrial fibrillation (AF) can be detected in nearly 25% of all patients with stroke by sequentially combining different electrocardiographic methods. Prediction of early cardio-embolic stroke remain a permanent challenge in everyday practice. The early identification of an increased risk for atrial fibrillation episodes (which are frequently asymptomatic) is essential for the prevention of cardioembolic events. One of the noninvasive modalities of atrial fibrillation prediction is represented by the electrocardiographic P-wave analysis. This includes study and diagnosis of interatrial conduction block. Our short case report presents a case with ischemic cortico-sottocortical stroke involving capsulo and caudo regions in a woman patient with interatrial block as realized by electrocardiographic P analysis.
