Standard Versus Intensive Monitoring After Myocardial Infarction Looking for Atrial Fibrillation

After a myocardial infarction (MI), patients discharged home in sinus rhythm may develop AF that is asymptomatic, undetected, and undertreated. Previous studies (CARISMA and ARREST) have d...

Prevalence of Sub-Clinical Atrial Fibrillation in Elderly Patients With Hypertension, Detected Using an External Loop Recorder

The ASSERT-III study aims to determine the incidence of sub-clinical (silent) atrial fibrillation (AF) among elderly patients with hypertension and at least one other risk factor for AF. ...

Implantable Loop Recorder Versus Conventional Ambulatory Monitoring in Detecting Atrial Fibrillation After Pulmonary Vein Isolation

The primary aim of the study is to assess the efficacy of continuous rhythm monitoring with an implantable loop recorder (ILR) compared to conventional ambulatory electrocardiography in de...

Detection of Silent Atrial Fibrillation aFter Ischemic StrOke

The primary objective of this study is to evaluate whether, in patients with first-ever atherothrombotic or lacunar stroke without any previous history of atrial fibrillation (AF)/atrial f...

The Comparative Efficacy of the Zio Patch vs Implantable Loop Recorder in Atrial Fibrillation

The aim of our study is to investigate if LTCM's are superior to implantable loop recorders in detecting atrial fibrillation after pulmonary vein isolation. This study will provide insight...

Atrial flutter and embolic risk: The relationship between atrial flutter cycle length and left atrial appendage function.

The potential for thromboembolism in atrial flutter (AFL) is different from atrial fibrillation. AFL cycle length (AFL-CL) may be related to reduced left atrial appendage (LAA) function. Very rapid AF...

Disease progression after ablation for atrial flutter compared with atrial fibrillation: A nationwide cohort study.

The aim of this study was to study the risk of death and development of arrhythmia and/or subsequently heart failure after an atrial flutter ablation procedure compared with an atrial fibrillation (AF...

Insertable cardiac monitor detection of silent atrial fibrillation in candidates for percutaneous patent foramen ovale closure.

An underlying atrial vulnerability or a preexisting misdiagnosed atrial fibrillation in some patients who are candidates for patent foramen ovale (PFO) closure may lead to an unnecessary percutaneous ...

Comparison of Clinical Outcomes Among Patients With Atrial Fibrillation or Atrial Flutter Stratified by CHA2DS2-VASc Score.

Current guidelines support treating atrial fibrillation (AF) and atrial flutter (AFL) as equivalent risk factors for ischemic stroke stratified by CHA2DS2-VASc scores, recommending anticoagulation the...

Atrial fibrillation in elderly patients with implantable loop recorders for unexplained syncope.

An implantable loop recorder (ILR) assists in the diagnosis of unexplained syncope and atrial fibrillation (AF). Both become prevalent with age. Limited data exist describing the incidence of AF as th...

Medical and Biotech [MESH] Definitions

Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).

Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.

A potentially lethal cardiac arrhythmia characterized by an extremely rapid, hemodynamically unstable ventricular tachycardia (150-300 beats/min) with a large oscillating sine-wave appearance. If untreated, ventricular flutter typically progresses to VENTRICULAR FIBRILLATION.

Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.

A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)
