Electrocardiographic Left Atrial Abnormality and Risk of Stroke: Northern Manhattan Study Clinical Sciences
Conclusions— ECG-defined left atrial abnormality was associated with incident cryptogenic or cardioembolic stroke independently of the presence of AF, suggesting atrial thromboembolism may occur without recognized AF.

Abnormal P-Wave Axis and Ischemic Stroke Clinical Sciences
Conclusions—aPWA is independently associated with ischemic stroke. This association seems to be stronger for cardioembolic strokes. Collectively, our findings suggest that alterations in atrial electric activation may predispose to cardiac thromboembolism independent of atrial fibrillation.

Improved Detection of Silent Atrial Fibrillation Using 72-Hour Holter ECG in Patients With Ischemic Stroke: A Prospective Multicenter Cohort Study Clinical Sciences

Atrial Cardiopathy and the Risk of Ischemic Stroke in the CHS (Cardiovascular Health Study) Clinical Sciences
Conclusions—In addition to clinically apparent AF, other evidence of abnormal atrial substrate is associated with subsequent ischemic stroke. This finding is consistent with the hypothesis that thromboembolism from the left atrium may occur in the setting of several different manifestations of atrial disease.

Troponin Elevation Predicts Atrial Fibrillation in Patients with Stroke or Transient Ischemic Attack
Conclusions: cTnI elevation predicts new-onset AF on 24-hour Holter measurement in patients with acute ischemic stroke or TIA and may indicate a poorer prognosis and a higher risk of stroke, MI, and death at 3 months.

Electrocardiographic Monitoring for Detecting Atrial Fibrillation After Ischemic Stroke or Transient Ischemic Attack: Systematic Review and Meta-Analysis Original Articles
Conclusions— Longer duration of electrocardiographic monitoring after cryptogenic stroke is associated with a greater detection of AF. Future investigation is needed to determine the optimal duration of long-term monitoring.

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 ...

Detection of paroxysmal atrial fibrillation by prolonged electrocardiographic recording after ischaemic stroke in patients aged
CONCLUSION: This prospective observational study showed a low rate of paroxysmal AF among young patients presenting with stroke, on the basis of 21-day cardiac monitoring. This result highlights the need to identify patients who would benefit from such long monitoring. PMID: 25669959 [PubMed - as supplied by publisher]

Atrial fibrillation burden and atrial fibrillation type: Clinical significance and impact on the risk of stroke and decision making for long-term anticoagulation.
Abstract Atrial fibrillation (AF) is a common arrhythmia increasing the risk of morbidity and adverse outcomes (stroke, heart failure, death). AF is found in 1-2% of the general population, with increasing prevalence with aging. Its exact epidemiological profile is incomplete and underestimated, because 10-40% of AF patients (particularly the elderly) can be asymptomatic ("clinically silent or subclinical AF"), with occasional electrocardiographic diagnosis. The research interest on silent AF has increased by the evidence that its outcome is no less severe, in terms of risks of stroke and death, than that for symp...

Stress-induced cardiomyopathy accompanied by heat stroke
We describe a case with high body temperature and coma, who also presented with wide QRS tachycardia and shock. He was initially treated for heat stroke and wide QRS tachycardia. Serial electrocardiographic change and echocardiographic findings suggested this was complicated with stress-induced cardiomyopathy. This case demonstrates the importance of recognizing that serious myocardial damage can result from heat stroke. <Learning objective: Heat stroke can cause multiple organ failure and the presentation of circulatory failure in heat stroke may be the sign of myocardial dysfunction. To distinguish acute coronary ...

Atrial fibrillation detected by continuous electrocardiographic monitoring using implantable loop recorder to prevent stroke in individuals at risk (the LOOP study): Rationale and design of a large randomized controlled trial
Conclusion The LOOP study will evaluate health benefits and cost-effectiveness of ILR as a screening tool for AF to prevent stroke in patients at risk. Secondary objectives include identification of risk factors for the development of AF and characterization of arrhythmias in the population. The trial holds the potential to influence the future of stroke prevention.

Association of ventricular arrhythmia and in-hospital mortality in stroke patients in Florida: A nonconcurrent prospective study
Abstract: Stroke remains one of the leading causes of death in the United States. Current evidence identified electrocardiographic abnormalities and cardiac arrhythmias in 50% of patients with an acute stroke. The purpose of this study was to assess whether the presence of ventricular arrhythmia (VA) in adult patients hospitalized in Florida with acute stroke increased the risk of in-hospital mortality. Secondary data analysis of 215,150 patients with ischemic and hemorrhagic stroke hospitalized in the state of Florida collected by the Florida Agency for Healthcare Administration from 2008 to 2012. The main outcome for th...

Relation between index of cardioelectrophysiological balance and stroke severity in patients with acute ischemic stroke
Conclusion: Our results suggested that iCEB is associated with stroke severity on admission in patients with acute ischemic stroke. It is known that high iCEB is associated with torsade de pointes (TdP), ventricular tachycardia.

Clinically important atrial arrhythmia and stroke risk: a UK-wide online survey among stroke physicians and cardiologists
Conclusions: There is a lack of consensus on the diagnosis and management of patients with brief runs of atrial arrhythmia detected on ambulatory ECG. Further research is needed to clarify the risk of stroke in this unique population of patients.
