Cardiac Arrhythmia
Definitions related to atrial flutter:
-
A disorder characterized by an electrocardiographic finding of an organized, regular atrial rhythm with atrial rate of 240-340 beats per minute. Multiple P waves typically appear in the inferior leads in a saw tooth-like pattern between the QRS complexes. (CDISC)NCI ThesaurusU.S. National Cancer Institute, 2021
-
A rapid heart rate, associated with a regular rhythm, that is caused by abnormal electrical activity within the atria.U.S. FDA GlossaryU.S. Food & Drug Administration, 2021
-
A type of atrial arrhythmia characterized by atrial rates of between 240 and 400 beats per minute and some degree of atrioventricular node conduction block. Typically, the ventricular rate is half the atrial rate. In the EKG; atrial flutter waves are observed as sawtooth-like atrial activity. Pathophysiologically, atrial flutter is a form of atrial reentry in which there is a premature electrical impulse creates a self-propagating circuit.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
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).NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
A disorder characterized by a dysrhythmia with organized rhythmic atrial contractions with a rate of 200-300 beats per minute. The rhythm disturbance originates in the atria.Common Terminology Criteria for Adverse EventsU.S. National Institutes of Health, 2021
-
Atrial flutter is a rapid regular atrial rhythm due to an atrial macroreentrant circuit. Symptoms include palpitations and sometimes weakness, effort intolerance, dyspnea, and presyncope. Atrial thrombi may form and embolize. Diagnosis is by electrocardiography. Treatment involves rate control with drugs, prevention of thromboembolism...Merck & Co., Inc., 2020
-
Atrial flutter is a cardiac arrhythmia characterized by atrial rates of 240-400 beats/min, usually with some degree of atrioventricular (AV) node conduction block. In the most common form of atrial flutter (type I atrial flutter), electrocardiography (ECG) demonstrates a negative sawtooth pattern in leads II, III, and aVF.WebMD, 2019
-
In atrial flutter, your heart's upper chambers (atria) beat too quickly. This causes the heart to beat in a fast, regular rhythm.Mayo Foundation for Medical Education and Research
-
Typical atrial flutter (counterclockwise cavotricuspid isthmus-dependent atrial flutter) is a macroreentrant atrial tachycardia with atrial rates usually above 250 bpm up to 320 bpm. It results from organized electrical activity in which large areas of the atrium take part in the reentrant circuit. The typical form depends on the...Athenahealth, Inc., 2019
