Journal of Electrocardiology, 51(6), 1091-1093. https://doi.org/10.1016/j.jelectrocard.2018.09.0040022-07361532-8430http://hdl.handle.net/11268/7709The diagnosis of advanced interatrial block (A-IAB) is done by surface ECG analysis when the P-wave ≥120 ms with biphasic (±) morphology in leads II, III and aVF. In this brief communication, we advance a new concept involving atypical patterns of A-IAB due to changes about the morphology or duration of the P-wave. It remains to be determined its real prevalence in different clinical scenarios, and whether these atypical ECG patterns should be considered as predictors of atrial fibrillation/stroke.engjournal article10.1016/j.jelectrocard.2018.09.004restricted accessElectrocardiografíaFibrilación auricularEnfermedad cardiovascularMedicina preventiva
