Diagnosis of atrial fibrillation in young patients with ischemic stroke: A systematic review and meta-analysis
The recommended cardiac rhythm evaluation to determine the etiology of ischemic stroke (IS) is similar in all patients regardless of their age and includes an electrocardiogram and at least a 24-hour heart rhythm monitoring. However, it is known that the main causes of IS vary according to patients ’ age. There is a higher preponderance of arterial dissections and patent foramen ovale in younger patients, while atrial fibrillation (AF) is more common in older patients.

Prognostic Significance of Fragmented QRS in Patients with Acute Ischemic Stroke
Stroke is a leading cause of mortality and morbidity in developed countries1 and has a strong relationship with cardiovascular system disorders.2 Due to this relationship, the connection between brain and heart has become increasingly important and neurocardiology has emerged as a popular concept over the recent years.3 Electrocardiographic abnormalities and various cardiac arrhythmias occurring especially after stroke support this phenomenon.4 ST segment and/or T-wave abnormalities without myocardial ischemia,5 left axis deviation, QT prolongation,6 QT dispersion,7 atrial fibrillation (AF), sinus tachycardia, ventricular ...

Inversion of T Waves on Admission is Associated with Mortality in Spontaneous Intracerebral Hemorrhage
Cardiac dysfunction directly caused by spontaneous intracerebral hemorrhage (ICH) is a poorly understood phenomenon, and its impact on outcome is still uncertain. The aim of this study is to investigate the relationship between electrocardiographic (EKG) abnormalities and mortality in ICH.

Electrocardiographic left atrial abnormality in patients presenting with ischemic stroke
P wave indices represent electrocardiographic marker of left atrial pathology. We hypothesized that P wave would be more abnormal in patients presenting with ischemic stroke than a comparable group without ischemic stroke.

Association between electrocardiographic and echocardiographic atrial abnormalities and prognosis in cryptogenic stroke
The role of atrial fibrillation in cryptogenic stroke (CS) is well known. However, the usefulness of left atrial (LA) electrical and morphological abnormalities to identify more disabling strokes in sinus rhythm patients is less studied. We evaluated the association between electrocardiographic P-wave abnormalities and echocardiographic LA measures with neurological disability in patients with cryptogenic stroke.

Left Atrial Dilation and Risk of One-Year Readmission after Embolic Stroke of Undetermined Source
: Structural left atrial and ventricular abnormalities on the electrocardiogram (ECG) and transthoracic echocardiogram (TTE) at the time of ischemic stroke have been associated with morbidity and mortality. Yet, the prognostic impact of the same in embolic stroke of undetermined source (ESUS), a relevant subtype of ischemic stroke with a unique pathophysiology, has not been well studied to date. Our aim was to assess the predictive impact of left atrio-ventricular ECG and TTE abnormalities on one-year hospital readmission after ESUS from an ongoing single center prospective stroke registry in the U.S.

Automated Continuous Electrocardiogram Monitoring Accelerates the Detection of Atrial Fibrillation after Ischemic Stroke or Transient Ischemic Attack on a Hyper Acute Stroke Unit
Background and Aim: Rapid and sensitive detection of atrial fibrillation (AF) is of paramount importance for initiation of adequate preventive therapy after stroke. Stroke Unit care includes continuous electrocardiogram monitoring (CEM) but the optimal exploitation of the recorded ECG traces is controversial. In this retrospective single-center study, we investigated whether an automated analysis of continuous electrocardiogram monitoring (ACEM), based on a software algorithm, accelerates the detection of AF in patients admitted to our Stroke Unit compared to the routine CEM.

Supraventricular Extrasystoles on Standard 12-lead Electrocardiogram Predict New Incident Atrial Fibrillation after Embolic Stroke of Undetermined Source: The AF-ESUS Study
Background: The diagnosis of covert atrial fibrillation (AF) remains a major challenge to guide secondary prevention of patients with embolic stroke of undetermined source (ESUS). Aims: We analyzed consecutive ESUS patients from 3 prospective stroke registries to assess whether the presence of supraventricular extrasystoles (SVE) on standard 12-lead electrocardiogram (ECG) is associated with the detection of AF (primary outcome), stroke recurrence and death (secondary outcomes) during follow-up.

Burden of Premature Atrial Complexes and Risk of Recurrent Stroke and Death in Patients with Mild to Moderate Ischemic Stroke
Premature atrial complexes (PACs) meet increased attention as a potential intermediary between sinus rhythm and atrial fibrillation (AF). Patients with even high numbers of PACs do not fulfill current guidelines for oral anticoagulation treatment though an associated stroke risk is suspected. Objective: We aimed to determine whether a high number of PACs or runs of AF less than 30 seconds in 2-day continuous electrocardiogram (ECG) recording was associated with risk of recurrent ischemic stroke/transient ischemic attack (TIA) or death in a large cohort of patients with acute ischemic stroke or TIA and no prior AF.

T2*-Weighted MRI Detected Dilated Cerebral Veins in a Patient With Acute-Phase Cerebral Venous Sinus Thrombosis —A Case Report
We describe a 45-year-old man who presented with nausea, vomiting, and strong occipital headache on the right side. Although no abnormalities on neurological examination or computed tomography imaging were found on admission, peripheral blood cell counts showed polycythemia (hemoglobin 20.6 g/dL) and electrocardiography demonstrated atrial fibrillation. Therefore, anticoagulant treatment with heparin was started immediately. On the following day, the occipital headache continued. Brain T2*-weighted (T2*WI) magnetic resonance imaging (MRI) and, to a lesser extent, susceptibility-weighted imaging showed dilation of numerous ...

Does the Magnitude of the Electrocardiogram QT Interval Dispersion Predict Stroke Outcome?
QT dispersion, maximal interlead difference in QT interval on 12-lead electrocardiogram (ECG), measures cardiac repolarization abnormalities. Data are conflicting whether QT dispersion predicts adverse outcome in acute ischemic stroke (AIS) patients. Our objective is to determine if QT dispersion predicts: (1) short-term clinical outcome in AIS, and (2) stroke location (insular versus noninsular cortex).

Clinical Outcome of Ischemic Stroke in Old Patients Versus Oldest-Old
Background: It is unclear whether very old patients benefit from stroke unit. The aim of our work was to compare the clinical outcome of patients with ischemic stroke aged either 70 or 80 (G 1) versus oldest-old greater than or equal to 81years (G 2). Methods: Of 1187 patients admitted with stroke during 5 years in our stroke unit, we included 252 patients with independent functional status (modified Rankin scale, [mRS] ≤ 2) before the stroke. All patients underwent clinical examination, blood test, electrocardiography, brain imaging, and cerebrovascular ultrasound.
