Alterations of normal intra- and interatrial conduction are a common outcome of multiple cardiovascular conditions. They arise most commonly in the context of advanced age, cardiovascular risk factors, organic heart disease, atrial fibrosis, and left atrial enlargement. Interatrial block (IAB), the most frequent and extensively studied atrial conduction disorder, affects up to 20% of the general primary care population. IAB can be partial (P wave duration ≥ 120 ms on any of the 12 ECG leads) or advanced (P wave ≥ 120 ms and biphasic morphology (positive-negative) in inferior leads). Advanced IAB is an independent risk factor for supraventricular tachyarrhythmias and embolic stroke in a variety of clinical settings. Advanced IAB is a cause of left atrial electromechanical dysfunction and left atrioventricular dyssynchrony and has been associated with left ventricular diastolic dysfunction. P wave duration is associated with cardiovascular and all-cause mortality in the general population. Atrial conduction abnormalities should be identified as markers of atrial remodeling, prognostic indicators, and, in the case of advanced IAB, a true arrhythmologic syndrome. IAB and other P wave abnormalities should prompt the search for associated conditions, the treatment of which may partially reverse atrial remodeling or prevent it if administered upstream. Future studies will help define the role of preventive therapeutic interventions in high-risk patients, including antiarrhythmic drug therapy and oral anticoagulation. Implications for the treatment of heart failure and for pacing should also be further investigated.

“…Since advanced IAB is a strong predictor of supraventricular arrhythmias in a variety of clinical scenarios, 1 and possibly also in hemodialysis patients, 10 recognition of Bayés syndrome is not a merely academic issue. Most likely poor awareness of IAB, more so by nephrologists, accounts for lack of recognition of this syndrome.…”

A chronic hemodialysis patient-known to have advanced interatrial block (IAB)-had reported symptoms suggesting arrhythmias, hence she underwent hemodialysis treatment while on the cardiac monitor. This allowed us to recognize the occurrence of paroxysmal atrial fibrillation and, in turn, disclose the first case of Bayés syndrome. Even though atrial fibrillation and IAB are very frequent in hemodialysis patients, Bayés syndrome, that comprehends both, has never been described, likely because the IAB is often overlooked and undiagnosed. This case could improve the awareness of IAB and of the Bayés syndrome in hemodialysis population.

“…Among hemodialysis patients, the prevalence of partial and advanced IAB was 49.3% and 7%, respectively [ 17 ]. It has also been suggested that IAB is an independent risk factor for stroke [ 18 , 19 , 20 ], cognitive impairment [ 21 , 22 , 23 ], dementia [ 21 ], atrial cardiomyopathy such as a rare presentation of a laminopathy [ 24 ], thrombotic events, acute respiratory distress syndrome (ARDS) in need of intubation [ 25 ] and cardiovascular mortality in several clinical settings [ 26 , 27 ]. Advanced IAB has been described as a sign of uremic cardiomyopathy among patients with chronic kidney disease (CKD) in hemodialysis [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]; however, no data are available on the prevalence of both partial and advanced IAB among different stages of CKD.…”

Background and Objective: Interatrial block (IAB) is defined as a conduction delay between the right and left atria. No data are available about the prevalence of both partial IAB and advanced IAB among the different stages of chronic kidney disease. The aim of this study was to describe the prevalence and type of advanced IAB across the spectrum of renal function, including patients on dialysis and the clinical characteristics associated with advanced IAB. Materials and Methods: Retrospective, single-center study of 151 patients consecutively admitted to the Nephrology and Ophthalmology Unit for 3 months. The study population was divided into three groups according to stages of chronic kidney disease. We evaluated the prevalence and pattern of IAB among the groups and the clinical characteristics associated with advanced IAB. Results: The prevalence of partial IAB was significantly lower in end-stage kidney disease (ESKD) group compared to control group (36.7% vs. 59.6%; p = 0.02); in contrast the prevalence of advanced IAB was significantly higher in both chronic kidney disease (CKD) (17.8% vs. 5.3%, p = 0.04) and ESKD group (24.5% vs. 5.3%, p = 0.005) compared to control group. The atypical pattern of advanced IAB was more frequent in both the ESKD and CKD group than in the control group (100% and 75% vs. 33.3%; p = 0.02). Overall, among patients that showed advanced IAB, 17 (73.9%) showed an atypical pattern by morphology and 2 (8.7%) showed an atypical pattern by duration of advanced IAB. The ESKD group was younger than the control group (65.7 ± 12.3 years vs. 71.3 ± 9.9 years; p = 0.01) and showed a higher prevalence of beta blockers (42.9% vs. 19.3%; p = 0.009), as in the CKD group (37.8% vs. 19.3%; p= 0.04). Conclusions: The progressive worsening of renal function was associated with an increasing prevalence of advanced IAB. Advanced IAB may be a sign of uremic cardiomyopathy and may suggest further evaluation with long-term follow-up to investigate its prognostic significance in chronic kidney disease.
