Po-04-151 a new sequential artificial intelligence algorithm for predicting atrial fibrillation using serial 12-lead electrocardiograms
Because the early stage of atrial fibrillation (AF) is difficult to detect, a significant number of patients are exposed to the risk of stroke without forewarning. Artificial intelligence (AI) algorithms using 12-lead electrocardiograms (ECGs) are being developed to detect AF early.

Dh-452784-2 identifying atrial fibrillation with sinus rhythm electrocardiogram using artificial intelligence in embolic stroke with undetermined source
Previous studies have demonstrated acceptable ranges of accuracy of artificial intelligence (AI) algorithms for identifying patients with paroxysmal atrial fibrillation (AF) based on their sinus rhythm electrocardiograms (ECGs). However, none of them has been validated in patients with embolic stroke with undetermined source (ESUS) in which thorough AF screening is required.

Po-05-141 association of interatrial block and the development of atrial fibrillation among patients with hypertrophic cardiomyopathy
Atrial fibrillation (AF) is the most common sustained arrhythmia among those with hypertrophic cardiomyopathy (HCM), affecting 1 in 5 patients. The combination of HCM and AF is associated with an increased risk of stroke, heart failure, and mortality. Interatrial block (IAB) is a distinct electrocardiographic (ECG) pattern describing conduction delay between the right and left atria through Bachmann ’s bundle. IAB has been identified as a predictor of AF across several disease states including congestive heart failure, valvular disease, and cardiac amyloidosis.

Po-05-136 in stroke patients, do baseline electrocardiogram findings correlate with diagnostic findings on long-term monitoring with implantable loop recorder?
In patients with cryptogenic stroke, long-term monitoring is standard-of-care to exclude atrial tachyarrhythmias. Prior studies have not examined interatrial block (IAB) and other ECG markers paired with long-term continuous monitoring (the current gold standard) to predict likelihood of atrial fibrillation (AF) detection in stroke patients.

Electrocardiographic P terminal force in lead V1, its components, and the association with stroke and atrial fibrillation or flutter
The electrocardiographic (ECG) marker P terminal force V1 (PTFV1) is generally perceived as a marker of left atrial pathology and has been associated with atrial fibrillation or flutter (AF).

Po-625-05 electrocardiographic deep terminal negative of the p wave in v1 and ischemic stroke:the atherosclerosis risk in communities (aric) study
Abnormal P-wave indices are associated with ischemic stroke independent of atrial fibrillation (AF). Deep terminal negative of the P wave in V1 (DTNPV1) is a simple ECG index that reflects underlying left atrial remodeling. However, it is unknown whether DTNPV1 is associated with ischemic stroke.

Po-661-03 use of a deep learning algorithm to predict paroxysmal atrial fibrillation based on printed electrocardiographic records acquired during sinus rhythm
Atrial fibrillation (AF) is a common type of sustained arrhythmia worldwide. Asymptomatic AF, which occurs frequently, is associated with an increased incidence of ischemic stroke, heart failure, and mortality. A large number of patients with paroxysmal atrial fibrillation (PAF) remain undiagnosed due to the absence of electrocardiographic evidence of AF (AF-ECGs). If PAF could be predicted, targeted screening could improve early detection and treatment of this condition.

B-po02-045 utility of a smartphone connected electrocardiogram recorder for detecting atrial fibrillation in post-stroke patients
Atrial fibrillation is one of the important causes of ischemic stroke. Routine 24-hour monitoring reveals latent atrial fibrillation in up to about 5% of cases. Despite the fact that today there are many ways to record heart rate, there is no precise algorithm that allows to detect atrial fibrillation in patients who have survived ischemic stroke of unknown etiology.

Bernstein and colleagues (JAMA 2021; 325:2169-2177. PMID: 34061145) evaluated whether long term monitoring with an implantable cardiac monitor (ICM) is more effective than usual care for AF detection in patients with stroke from large- or small-vessel disease. Overall, 242 patients were randomized to ICM insertion within 10 days of the index stroke. Patients in the control group (n = 250) received site-specific usual care with external cardiac monitoring, such as 12-lead electrocardiograms, Holter monitoring, telemetry, or event recorders.

Utility and Limitations of Long-Term Monitoring of Atrial Fibrillation Using an Implantable Loop Recorder
Atrial fibrillation (AF) is the most common cardiac arrhythmia diagnosed and treated in the world. The treatment of patients ’ symptoms as well as the prevention of stroke and heart failure is dependent on accurate detection and characterization of AF. A variety of electrocardiographic (ECG) monitoring techniques are being used for these purposes. However, these intermittent ECG monitoring techniques have been shown to under diagnose AF events, while having limited ability to characterize AF burden and density.
