2024年10月8日 · Atrial flutter is a form of supraventricular tachycardia caused by a re-entry circuit within the right atrium. The length of the re-entry circuit corresponds to the size of the right atrium, resulting in a fairly predictable atrial rate of around 300 bpm (range 200-400)

ECG in atrial flutter. The ECG shows regular flutter waves (F-waves; not to be confused with f-waves seen in atrial fibrillation) which gives the baseline a saw-tooth appearance. Atrial flutter is the only diagnosis causing this baseline appearance, which is why it …

Atrial flutter is a cardiac arrhythmia characterized by rapid, regular atrial depolarizations at a characteristic rate of approximately 300 beats/min and a typically regular ventricular rate of approximately 150 beats/min (image 1). This topic will discuss the epidemiology, clinical presentation, diagnosis, and management of atrial flutter.

2022年12月8日 · Typical atrial flutter is seen in the electrocardiogram as continuous negative modulation in inferior leads (II, III, and AVF) and flat atrial deflections in leads I and aVL; this is due to the way of propagation and activation of the macro-reentrant circuit as described in the pathophysiology section.

Atrial flutter occurs when a “ reentrant ” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the...

Atrial flutter is typically caused by a re-entry circuit that is contained within the atria. These re-entry circuits are very fast. They are typically cycling 300 times a minute. If you can see the just the P waves (with the QRS removed), the P waves will look like the teeth of a saw and sometimes called "sawtooth".

A-flutter is a rhythm that is similar to atrial fibrillation in that the atria are not firing correctly. Unfortunately, the atria are firing at a rapid rate which affects how they empty of blood. Instead of contracting properly, they cause blood to pool in the atria and this could lead to …

2022年11月10日 · This article is a guide for interpreting abnormal Atrial Flutter EKGs, including qualifying criteria and a sample EKG rhythnm strip. Atrial flutter is an abnormally fast heart rate where the atria contract rapidly do not adequately pump blood to the ventricles.

2007年9月1日 · To improve diagnostic accuracy, we sought to develop and validate criteria 3 for the diagnosis of atrial flutter. The simple criteria of F waves in the frontal plane and a partially or completely regular ventricular response had a sensitivity of 90% and specificity of 100% based on arrhythmia diagnoses confirmed with intracardiac recordings.

The simple criteria of F waves in the frontal plane and a partially or completely regular ventricular response can be used to improve the differentiation of atrial flutter from atrial fibrillation based on the ECG.
