Similar to atrial fibrillation, atrial flutter can be classified into the following types: Acute atrial flutter (includes newly diagnosed cases). Paroxysmal atrial flutter. Chronic atrial flutter. The observant will notice that the classification differs slightly from that of atrial fibrillation.
People with atrial flutter have a heart rhythm that's more organized and less chaotic than that of atrial fibrillation. Sometimes you may have episodes of both atrial flutter and atrial fibrillation. People with atrial flutter may not have symptoms.
Atrial fibrillation (AFib) is a type of irregular heartbeat. If you have it, your doctor will classify yours by the reason for it and on how long it lasts. When your heartbeat returns to normal within 7 days, on its own or with treatment, it's known as paroxysmal atrial fibrillation. It can happen a few times a year or as often as every day.
However, most cardiac conditions may be associated with atrial flutter. As compared with several other supraventricular tachyarrhythmias, atrial flutter does not occur among otherwise healthy individuals. Atrial flutter causes characteristic ECG changes, as discussed below.
Paroxysmal atrial fibrillationI48. 0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.The 2022 edition of ICD-10-CM I48. 0 became effective on October 1, 2021.This is the American ICD-10-CM version of I48. 0 - other international versions of ICD-10 I48.
I48.0ICD-10 code I48. 0 for Paroxysmal atrial fibrillation is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
ICD-10 code: I48. 0 Paroxysmal atrial fibrillation.
427.31Atrial fibrillation/flutter Most studies used code 427.31 (atrial fibrillation), whereas four studies explicitly included atrial flutter (ICD-9 code 427.32).
Paroxysmal AFib are episodes of AFib that occur occasionally and usually stop spontaneously. Episodes can last a few seconds, hours or a few days before stopping and returning to normal sinus rhythm, which is the heart's normal rhythm. Some people may have single episodes of AFib.
Normally, the top chambers (atria) contract and push blood into the bottom chambers (ventricles). In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, so you may have four atrial beats to every one ventricular beat.
Paroxysmal A-fib occurs when there are abnormal electric pathways in the heart and the heart is not beating regularly or pumping enough oxygen-rich blood around the body. Share on Pinterest Paroxysmal A-fib may be caused by lifestyle choices such as illegal drugs, smoking, alcohol, obesity, and excessive exercise.
The definition of atypical atrial flutter includes a broad spectrum of other macroreentrant tachycardias in which the wave front does not travel around the tricuspid annulus.
Atrial fibrillation (A-fib) is an irregular and often very rapid heart rhythm (arrhythmia) that can lead to blood clots in the heart. A-fib increases the risk of stroke, heart failure and other heart-related complications.

In ICD-9, essential hypertension was coded using 401.0 (malignant), 401.1 (benign), or 401.9 (unspecified). ICD-10 uses only a single code for individuals who meet criteria for hypertension and do not have comorbid heart or kidney disease. That code is I10, Essential (primary) hypertension.
Atrial flutter tends to accompany atrial fibrillation, although some individuals may only present with atrial flutter. Similar to atrial fibrillation, atrial flutter can be classified into the following types: 1 Acute atrial flutter (includes newly diagnosed cases). 2 Paroxysmal atrial flutter. 3 Chronic atrial flutter.
Atypical atrial flutter is a consequence of cardiac surgery or extensive ablation therapy. These interventions may cause atrial flutters with very varying ECG appearance. However, flutter waves can still be seen and a history of ablation therapy or cardiac surgery will be sufficient for diagnosing an atypical atrial flutter.
The atrial rate (i.e the rate measured between flutter waves) typically ranges between 250 and 350 beats per minute (which is slower than the atrial rate in atrial fibrillation ). The atrioventricular node is not capable of conducting all impulses, which is why some impulses will be blocked.
In the most common type of atrial flutter, the re-entry loops around the tricuspid valve in a counter-clockwise direction.
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 must be recognized on the ECG. The flutter waves (on the contrary to f-waves in atrial fibrillation) have identical morphology (in each ECG lead). Flutter waves are typically best seen in leads II, III aVF, V1, V2 and V3. The exact appearance of the flutter waves will depend on the location and direction of the re-entry circuit. In the most common type of atrial flutter, the re-entry loops around the tricuspid valve in a counter-clockwise direction. This yields negative flutter waves in II, III and aVF and positive flutter waves in V1 ( Figure 1 ). If the re-entry has a clockwise direction, the flutter waves are positive in lead II, III, aVF and the P-waves typically have a notch on the apex. Please note that for most clinicians it is not necessary to be able to determine the direction of the re-entry loop.
This is due to the fact that atrial flutter is caused by a macro re-entry circuit (a large re-entry circuit) and re-entry circuits are vulnerable processes that usually self-terminate within minutes, hours or days.
In the vast majority of cases, the re-entry circuit in atrial flutter is located in the right atrium and it typically loops around the tricuspid valve. Impulses spread rapidly through the atria from this re-entry circuit. Examples of atrial flutter. Click to zoom.
There are effective treatments for atrial flutter, including medication or procedures designed to scar small areas of heart tissue (ablation).
Atrial flutter is similar to atrial fibrillation, a common disorder that causes the heart to beat in abnormal patterns. People with atrial flutter have a heart rhythm that's more organized and less chaotic than that of atrial fibrillation. Sometimes you may have episodes of both atrial flutter and atrial fibrillation.
