Electrocardiographic predictors of atrial fibrillation in patients with cryptogenic stroke

ConclusionAn increased p-wave duration, advanced interatrial block and high MVP score are associated with AF occurrence in patients with cryptogenic stroke. Identifying patients with these markers may be helpful as they may benefit from more exhaustive and prolonged monitoring.This article is protected by copyright. All rights reserved

To the Editor In a recent study, implantable electrocardiographic monitoring for 12 months resulted in detection of a significantly greater proportion of patients with atrial fibrillation compared with prolonged external monitoring for 30 days. The diagnostic yield of these 2 methods may be due to adherence as well as to the function of the monitoring device itself.

In Reply Dr Ito notes that adherence to monitoring may affect the diagnostic yield for wearable electrocardiographic monitors and suggests that poor adherence to external monitoring is responsible for the lower incidence of atrial fibrillation we found among patients with a recent ischemic stroke randomized to an external loop recorder vs an implantable loop recorder. However, our study data do not support that notion.

A 43-year-old woman was admitted for acute unusual headache, vertigo, and left upper limb weakness. She had been complaining of asthenia for the past few weeks. Her medical history included uterine cervix cancer treated with conisation and 2 pregnancies without serious complications. No allergy or recent drug introduction was noted. After ruling out current pregnancy, magnetic resonance imaging (MRI) was immediately performed and showed recent ischemic strokes in multiple territories. Doppler ultrasound imaging showed no carotid or vertebral arteries lesion. Electrocardiogram showed no ST elevation or atrial fibrillation, ...

ConclusionThe current study found that low ejection fraction, dilated left atrium, hypertension, smoking, old age, male gender, prolonged bypass time, prolonged cross clamping time, renal impairment, previous myocardial infarction, ungrafted dominant right coronary artery, low temperatures on bypass, early ischemic changes postoperative, hypokalemia, use of adrenaline and nor adrenaline, all of these factors were a significant predictors for development of atrial fibrillation after cardiac surgery.

uang Zhou Atrial fibrillation (AF) is the most frequently encountered cardiac arrhythmia and is often associated with other cardiovascular and cerebrovascular diseases, such as ischemic heart disease, chronic heart failure, and stroke. Automatic detection of AF by analyzing electrocardiogram (ECG) signals has an important application value. Using the contaminated and actual ECG signals, it is not enough to only analyze the atrial activity of disappeared P wave and appeared F wave in the TQ segment. Moreover, the best analysis method is to combine nonlinear features analyzing ventricular activity based on the detection ...

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.

P2-CHA2DS2-VASc score adds additional two points to the CHA2DS2-VASc score for an abnormal P wave axis to predict risk of stroke in atrial fibrillation (AF) [1]. The seminal study was an attempt to identify utility of P wave indices in sinus rhythm to predict the risk of stroke over and above the existing CHA2DS2-VASc score. P wave indices evaluated were prolonged P wave duration, abnormal P wave axis, advanced interatrial block and abnormal P wave terminal force in lead V1. They found that abnormal P wave axis which is an ECG correlate of left atrial abnormality improves the prediction of ischemic stroke. They concluded ...

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 ...

Eur J Gen Pract. 2021 Dec;27(1):152-157. doi: 10.1080/13814788.2021.1947237.ABSTRACTBACKGROUND: Ischaemic stroke or cerebrovascular accident (CVA) due to occult atrial fibrillation (AF) may cause severe morbidity and mortality. Diagnosing occult AF can be challenging and there is no consensus regarding the optimal duration of screening. A 24-hour Holter electrocardiogram (ECG) is frequently employed to detect occult AF following ischaemic CVA.OBJECTIVES: Demonstration of occult AF detection rate using a 24-hour Holter ECG in a primary care setting with descriptive analyses of independent variables to compare AF detected an...
