When it is blocked, P wave is prolonged >120 ms with a biphasic +/- morphology in the inferior leads (A-IAB pattern). If suspected, we suggest increasing the voltage and the speed of the ECG for better characterization. The anatomic substrate of A-IAB is atrial fibrosis involving BB, which explains why A-IAB is a marker of atriopathy with high specificity for the identification of left atria enlargement. BS is the association between A-IAB and atrial fibrillation/flutter. A-IAB is an easily identifiable and underestimated pattern that may encourage the clinician to look for runs of atrial fibrillation/flutter. A-IAB has been reported to be more prevalent among patients with embolic stroke. As we found atrial flutter in our patient, we began anticoagulation. We have still no evidence to prescribe anticoagulation for patients with A-IAB without atrial fibrillation/flutter and the results of prospective studies will be needed to design a randomized trial to assess the effect of anticoagulation in this population.</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Conflicts of interest</span><p id="par0020" class="elsevierStylePara elsevierViewall">The authors have no conflicts of interest to declare.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:1 [ 0 => array:2 [ "identificador" => "sec0005" "titulo" => "Conflicts of interest" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2019-11-12" "fechaAceptado" => "2020-06-11" "multimedia" => array:1 [ 0 => array:7 [ "identificador" => "fig0005" "etiqueta" => "Figure 1" "tipo" => "MULTIMEDIAFIGURA" "mostrarFloat" => true "mostrarDisplay" => false "figura" => array:1 [ 0 => array:4 [ "imagen" => "gr1.jpeg" "Alto" => 2352 "Ancho" => 2167 "Tamanyo" => 1383370 ] ] "descripcion" => array:1 [ "en" => "<p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">(A) Sinus rhythm at 66 bpm with a prolonged and +/- biphasic P wave in the inferior leads (red arrow: + component; blue arrow: - component), which meets the criteria of advanced interatrial block and a right bundle branch block.
