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 …

2025年2月2日 · Atrial Flutter on the Electrocardiogram. Atrial flutter is distinguishable on the electrocardiogram because it is a rhythmic tachycardia with heart rates that are divisors of 300 bpm, 150 bpm being the most frequent in untreated patients (AV conduction ratio 2:1).

2023年2月28日 · Electrocardiography (ECG or EKG) frequently makes the diagnosis by showing saw tooth flutter waves in several (II, III, aVF, and/or V1) of the 12 ECG leads recorded, indicating atrial tachycardia of about 250 – 350 bpm.

2022年1月26日 · Atrial flutter is often considered to be a subtype of atrial tachycardia and is characterized by a macro re-entry circuit, typically within the right atrium and involving the cavotricuspid isthmus (CTI-dependent or Type I flutter).

2022年12月8日 · Atrial flutter, a supraventricular arrhythmia, is one of the most common rhythm disturbances of the heart. A fast atrial rate with a fixed or variable ventricular rate characterizes it. Several atrial contractions to one ventricular contraction, and symptoms include fatigue, palpitations, and syncope.

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.

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...

2021年11月8日 · Atrial flutter is a common arrhythmia. It is a type of supra-ventricular tachycardia (SVT) and is similar to atrial fibrillation. This article is a guide for the ECG interpretation of Atrial Flutter, including a sample ECG strip. This is our online abnormal ECG interpretation cheat sheet!

2021年11月8日 · Atrial Flutter (sometimes called a flutter) occurs when there is an obstruction within the atrial electrical conduction system. Due to this impediment a series of rapid depolarizations occur. These depolarizations may occur …
