Rhythm control was defined as use of an antiarrhythmic medication, cardioversion, or AF ablation or surgery. We analyzed the Get With The Guidelines-Heart Failure (GWTG‐HF) registry linked to Medicare claims data from 2008 to 2014 to describe current treatments for rate versus rhythm control and subsequent outcomes in patients with heart failure with preserved ejection fraction and atrial fibrillation using inverse probability weighted analysis.

Patients with T-aIAB and At-aIAB have a similar prevalence of atrial fibrillation and stroke, so they must follow the same clinical management.Īdvanced Interatrial Block Atrial Fibrillation Bachmann’s Block Bayés’ Bloqueo de Bachmann Bloqueo interauricular Bloqueo interauricular avanzado Bloqueo interauricular de tercer grado Fibrilación auricular Interatrial block Syndrome Síndrome de Bayés Third Degree Interatrial Block. Only diabetes was associated with the risk of T-aIAB (odds ratio: 6.4 p = 0.002 95% confidence interval: 2.0-21.1).ĭiabetes mellitus is the only risk factor for an aIAB to be typical. The first one was associated with the existence of diabetes mellitus (p = 0.001), chronic kidney disease stage ≥ 3 (p = 0.036), atrioventricular block (p = 0.006) and a lower mean ventricular ejection fraction (p = 0.025) there were no differences regarding the prevalence of atrial fibrillation/flutter or stroke. It was compared the group of patients with typical aIAB (T-aIAB) and with At-aIAB. Statistical analysis was performed with SPSS 19.0 level of significance: p < 0.05.Ī total of 75 patients with an average age of 74.4 ± 11.7 years and with a 62.7% males, were included. The analysis of the P wave was made by increasing the size of the ECG and by electronic calipers. The analyzed variables were obtained from the computerized clinical history. Recently, four patterns of atypical aIAB (At-IAB) have been described based on the morphology and duration of the P wave, but it’s unknown if they share the same pathogenesis and clinical characteristics.Īn observational, descriptive and retrospective study was performed with patients, visited in cardiology, who have a sinus rhythm and with aIAB. It is called advanced interatrial block (IAB) to the existence of a P wave ≥ 120 ms and biphasic ± in the lower leads II-III-VF of the surface electrocardiogram (ECG), which constitutes a significant predictive factor for the development of atrial fibrillation. Los pacientes con BIA-T y BIA-At presentan similar prevalencia de fibrilación auricular y accidente cerebrovascular, por lo que son objeto de un mismo tratamiento clínico. La diabetes mellitus constituye el único factor de riesgo de que un BIA sea típico. El primero se relacionó con la existencia de diabetes mellitus (p = 0.001), enfermedad renal crónica estadio ≥ 3 (p = 0.036), bloqueo auriculoventricular (p = 0.006) y una menor fracción de expulsión ventricular media (p = 0.025) no hubo diferencias respecto de la prevalencia de fibrilación auricular/flúter o accidente cerebrovascular.
Se compararon los grupos de pacientes con BIA típico (BIA-T) y BIA-At. Se incluyó a 75 pacientes con media de edad de 74.4 ± 11.7 años, con 62.7% de varones. El análisis estadístico se realizó con SPSS 19.0, con nivel de significación de p < 0.05. El análisis de la onda P se efectuó al aumentar el tamaño del electrocardiograma y mediante calipers electrónicos. Las variables analizadas se obtuvieron de la historia clínica informatizada. En fecha reciente se han descrito cuatro patrones de BIA atípicos (BIA-At) con base en la morfología y la duración de la onda P, sin conocer si comparten patogenia y características clínicas similares.Įstudio observacional, descriptivo y retrospectivo de pacientes, visitados en el Servicio de Cardiología, en ritmo sinusal y con BIA. Se denomina bloqueo interauricular avanzado (BIA) a la existencia de una onda P ≥ 120 ms y bifásica +/- en las derivaciones inferiores (II-III-VF) del electrocardiograma (ECG) de superficie, el cual constituye un factor predictivo significativo del desarrollo de fibrilación auricular.
