Effect of Falls on Frequency of Atrial Fibrillation and Mortality Risk (From the REasons for Geographic And Racial Differences in Stroke REGARDS Study)
It is unclear if persons who have atrial fibrillation (AF) have a higher fall risk compared with those in the general population and if falls increase mortality beyond that observed in AF. A total of 24,117 (mean age=65±9.3; 55% female; 38% black) participants from the REasons for Geographic And Racial Differences in Stroke (REGARDS) study were included. AF was identified from baseline electrocardiogram data and by self-reported history. Falls were considered present if participants reported 2 or more falls within the year prior to the baseline examination.

Multiscale Entropy of the Heart Rate Variability for the Prediction of an Ischemic Stroke in Patients with Permanent Atrial Fibrillation
We examined whether a novel complexity measurement of the heart rate variability called multiscale entropy (MSE) was a useful risk stratification measure of ischemic strokes in patients with permanent AF. Methods and Results We examined 173 consecutive patients (age 69±11 years) with permanent AF who underwent 24-hour Holter electrocardiography from April 2005 to December 2006. We assessed several frequency ranges of the MSE and CHA2DS2-VASc score (1 point for congestive heart failure, hypertension, diabetes, vascular disease, an age 65 to 74 years, and a female sex and 2 points for an age≥75 years and a stroke or trans...

Insertable cardiac monitors after cryptogenic stroke – a risk factor based approach to enhance the detection rate for paroxysmal atrial fibrillation
ConclusionsThe detection rate of AF is one‐third after 1 year if candidates for an ICM after cryptogenic IS/TIA are selected by AF risk factors. LA dilation and atrial runs independently predict AF.

Differential Impact of Risk Factors in Blacks and Whites in the Development of Atrial Fibrillation: the Reasons for Geographic And Racial Differences in Stroke (REGARDS) Study
ConclusionModifiable risk factors are important in AF development among blacks despite a lower risk of the arrhythmia. Racial differences in the magnitude of the association of individual AF risk factors do not explain the AF paradox.

Editorial Atrial fibrillation and stroke: unrecognised and undertreated
When did you or your primary care physician last palpate your wrist to check for a regular heart rate? This simple action, followed by an electrocardiogram if the heart rate is irregular, might be crucial in preventing death and disability from ischaemic stroke, heart failure, or myocardial infarction. In this week's issue, we publish a clinical Series of three papers on atrial fibrillation ahead of the annual European Society of Cardiology (ESC) meeting held in Rome, Italy, Aug 27 –31. Atrial fibrillation is estimated to affect 33 million people worldwide.

Electrocardiographic and Echocardiographic predictors of paroxysmal atrial fibrillation detected after ischemic stroke
Detection of atrial fibrillation after ischemic stroke is challenging due to its paroxysmal nature. We aimed to assess predictors of paroxysmal atrial fibrillation using non-invasive surface ECG and transthora...

Usefulness of the MrWALLETS Scoring System to Predict First Diagnosed Atrial Fibrillation in Patients With Ischemic Stroke
In this study, we searched for echocardiographic parameters associated with first diagnosed AF, to form a scoring system for the identification of patients with AF. We examined 571 patients with ischemic stroke (72.7  ± 13.5 years, 50.6% women), subdivided into 4 groups: documented cause without AF, first diagnosed AF, known paroxysmal AF, and permanent AF. All patients underwent transthoracic echocardiography, brain computed tomography scan, carotid/vertebral ultrasound, and continuous electrocardiographic monitoring.

Atrial time and voltage dispersion are both needed to predict new-onset atrial fibrillation in ischemic stroke patients
Atrial fibrillation (AF) is a known risk factor for ischemic stroke. Electrocardiographic predictors of AF in population studies such as the Framingham Heart Study, as well as in hypertensive patients have dem...

Modified CHADS2 and CHA2DS2-VASc scores to predict atrial fibrillation in acute ischemic stroke patients
Publication date: Available online 23 February 2018 Source:Journal of Clinical Neuroscience Author(s): Rixia Liu, Xiaomeng Yang, Shuya Li, Yong Jiang, Yilong Wang, Yongjun Wang It is important to identify candidates who warrant extended cardiac monitoring after ischemic stroke. We investigated the predictive performance of the CHADS2 and CHA2DS2-VASc scores for previously unknown atrial fibrillation during in-hospital electrocardiographic monitoring. Patients were selected from a prospective trial in China. The clinical prediction of the scores was examined using the C statistic. Multivariate logistic regressions were per...

Electrocardiographic Predictors of Silent Atrial Fibrillation in Cryptogenic Stroke
Prolonged screening for the presence of atrial fibrillation (AF) is recommended after cryptogenic stroke (CS) and different electrocardiographic markers of atrial cardiopathy have been proposed as tools to identify patients at high-risk for AF.

Drug-Induced Arrhythmias: A Scientific Statement From the American Heart Association.
Abstract Many widely used medications may cause or exacerbate a variety of arrhythmias. Numerous antiarrhythmic agents, antimicrobial drugs, psychotropic medications, and methadone, as well as a growing list of drugs from other therapeutic classes (neurological drugs, anticancer agents, and many others), can prolong the QT interval and provoke torsades de pointes. Perhaps less familiar to clinicians is the fact that drugs can also trigger other arrhythmias, including bradyarrhythmias, atrial fibrillation/atrial flutter, atrial tachycardia, atrioventricular nodal reentrant tachycardia, monomorphic ventricular tachy...
