“…Among them, 36% exhibited an LA-Sr value of <26%, but this specific condition did not show associations with age, sex, or traditional cardiovascular risk factors, including diabetes, hypertension, or chronic kidney disease, nor did it correlate with a history of heart failure or ischemic cardiopathy (Table 1). Not even the CHA2DS2-VASc score revealed differences among patients with an LA-Sr < 26%, emphasizing the potential limitations in discerning thrombogenic risk based on the evidence in the literature regarding the predictive power of ECG and TTE data [10][11][12][13][14][15][16][17][18]29,30,[45][46][47][48].…”

“…Several P-wave abnormalities were points of interest in the present study. A-IAB had a stronger predictive value for supraventricular arrhythmias in many clinical scenarios (mainly atrial flluter and AF, wich is denominated Bayés' Syndrome), for cardioembolic stroke, and for dementia [14][15][16][17][18]25]. A consensus document classified IAB as partial or advanced [16].…”

“…Concerning the ECG, numerous parameters are linked to both LA enlargement and dysfunction [10][11][12][13][14][15][16][17][18][19][20][21]. The most extensively studied P-wave indices encompass the interatrial blocks (IAB), the P-wave terminal force in V1 (PTFV1), and P-wave axis and voltages (Table S1) [21][22][23][24][25].…”

(1) Background: Atrial cardiomyopathy constitutes an intrinsically prothrombotic atrial substrate that may promote atrial fibrillation and thromboembolic events, especially stroke, independently of the arrhythmia. Atrial reservoir strain is the echocardiography marker with the most robust evidence supporting its prognostic utility. The main aim of this study is to identify atrial cardiomyopathy by investigating the association between left atrial dysfunction in echocardiography and P-wave abnormalities in the surface electrocardiogram. (2) Methods: This is a community-based, multicenter, prospective cohort study. A randomized sample of 100 patients at a high risk of developing atrial fibrillation were evaluated using diverse echocardiography imaging techniques, and a standard electrocardiogram. (3) Results: Significant left atrial dysfunction, expressed by a left atrial reservoir strain < 26%, showed a relationship with the dilation of the left atrium (p < 0.001), the left atrial ejection fraction < 50% (p < 0.001), the presence of advanced interatrial block (p = 0.032), P-wave voltage in lead I < 0.1 mV (p = 0.008), and MVP ECG score (p = 0.036). (4) Conclusions: A significant relationship was observed between left atrial dysfunction and the presence of left atrial enlargement and other electrocardiography markers; all of them are non-invasive biomarkers of atrial cardiomyopathy.

“…Of those, the recording was not successful in 36 participants with entries such as "difficult to move," "wheelchair", "denial", "leg/hand amputated", "in geriatric chair", "massive hernia", "plaster in leg/ hand". In the further process, 19 ECGs were lost (diskette lost [9], coupling error [4], data reading failure [5], unspecific reason [1]). We also excluded subjects with ECGs showing supraventricular tachyarrhythmias according to Minnesota-code 8-4-1 (n=6), all prevalent atrial fibrillation and atrial flutter as defined previously (n=204), paced rhythm (Minnesota-code 6-8, n=4) and ectopic rhythm defined as totally negative P waves in the inferior leads (II, III, aVF) in computer analysis (n=24) leaving 6066 individuals in the final study sample.…”

“…Interatrial block (IAB) is a distinct electrocardiographic (ECG) pattern that has been studied with growing interest since it was first described in 1979 by Bayés de Luna (1). IAB is caused by conduction delay between the right and left atrium, probably resulting from local fibrosis.…”

Introduction Partial and advanced interatrial block (IAB) in the ECG represents inter-atrial conduction delay. IAB is associated with atrial fibrillation (AF) and stroke in the general population. Material and methodsA representative sample of Finnish subjects (n=6 354) aged over 30 years (mean 52.2 years, SD 14.6) underwent a health examination including a 12-lead ECG. Five different IAB groups based on automatic measurements were compared to normal P waves using multivariate-adjusted Cox proportional hazard model. Follow-up lasted up to 15 years. ResultsThe prevalence of advanced and partial IAB was 1.0% and 9.7%, respectively. In the multivariate model, both advanced (hazard ratio [HR] 1.63 [95% CI 1.00 -2.65]) and partial IAB (HR 1.39 [1.09 -1.77]) were associated with increased risk of AF. Advanced IAB was associated with increased risk of stroke or transient ischemic attack (TIA) independently of associated AF ). Partial IAB was also associated with increased risk of being diagnosed with coronary heart disease ).Discussion IAB is a rather frequent finding in the general population. IAB is a risk factor for AF and is associated with an increased risk of stroke or TIA independently of associated AF. Key messages1. Both partial and advanced interatrial block are associated with increased risk of atrial fibrillation in the general population.2. Advanced interatrial block is an independent risk factor for stroke and transient ischemic attack.3. The clinical significance of interatrial block is dependent on the subtype classification.

Background: Bachmann's bundle plays a crucial role in the physiology of interatrial signal conduction. In the 1970s, Bayes de Luna introduced the definition of interatrial blocks (IABs), which negatively influence atrioventricular (AV) synchrony and left atrial (LA) activation. We aimed to assess the potential of LA strain technology in evaluating the mechanics of LA in patients with correct conduction and IABs. Additionally, we measured the parameters of regurgitation in pulmonary veins (PV), which depend on the type of interatrial conduction. Material and methods: The study group comprised 51 patients (26 male, 25 female) with symptomatic COVID-19 and sinus rhythm. Our study analyzed their medical history, electrocardiography (ECG) and echocardiography, including the LA strain parameters. Results: Global peak atrial longitudinal strain (PALS) depended on P-wave duration, LA volume, left ventricular ejection fraction (LVEF) and inferior pulmonary veins (PV) regurgitation parameters. Global peak atrial contractile strain (PACS) statistically depends on the LVEF, LA volume and the P-wave morphology. Conclusions: The presence of IABs negatively influences PACS and PALS. Examining LA strain is complementary to accurate ECG, which may be helpful in everyday clinical practice, particularly in diagnosing heart failure with preserved ejection fraction (HFpEF) and as a predictor of new episodes of atrial fibrillation (AF).
