Atrial Fibrillation vs. Atrial Flutter
Atrial fibrillation and atrial flutter are both types of supraventricular tachycardias, but they have distinct characteristics and mechanisms. The difference between atrial fibrillation and atrial flutter is given below:
|
Characteristic |
Atrial Fibrillation (AF) |
Atrial Flutter (AFL) |
|
Definition |
An irregular and often rapid heart rate occurs when the two upper chambers (atria) experience chaotic electrical signals. |
A type of supraventricular tachycardia characterized by a regular but rapid heart rate due to a reentrant circuit in the atria. |
|
ECG Findings |
Irregularly irregular rhythm without distinct P waves; chaotic, fibrillatory baseline. |
Regular atrial activity with sawtooth-shaped flutter waves, usually at a rate of around 250-350 bpm. |
|
Atrial Rate |
350-600 beats per minute (bpm) |
250-350 beats per minute (bpm) |
|
Ventricular Rate |
Varies; can be fast, slow, or normal depending on AV node conduction. |
Typically 150 bpm if 2:1 conduction; may vary with different conduction ratios. |
|
Rhythm |
Irregularly irregular |
Regular (usually) but can be irregular if variable AV block. |
|
Mechanism |
Multiple reentrant circuits within the atria |
A single reentrant circuit within the right atrium |
|
Symptoms |
Palpitations, fatigue, shortness of breath, dizziness, chest pain, sometimes asymptomatic. |
Palpitations, fatigue, shortness of breath, dizziness, chest pain, sometimes asymptomatic. |
|
Risk Factors |
Hypertension, heart failure, coronary artery disease, valvular heart disease, hyperthyroidism, excessive alcohol consumption. |
Similar to AF: Hypertension, heart failure, coronary artery disease, valvular heart disease, hyperthyroidism, and excessive alcohol consumption. |
|
Prognosis |
Chronic conditions with a risk of stroke, heart failure, and other complications if not managed properly. |
Often less common and may be more amenable to catheter ablation; risk of stroke and other complications similar to AF. |
|
Epidemiology |
More common, particularly in older adults. |
Less common than AF |
Atrial Fibrillation Causes and Symptoms
Atrial Fibrillation (AFib) is an irregular, often rapid heart rhythm causing poor blood flow. Understanding Atrial Fibrillation diagnosis and symptoms helps in receiving the correct Atrial Fibrillation treatment. The Atrial Fibrillation life expectancy can be improved with proper management, lifestyle changes, and medical help.
This article explains Atrial Fibrillation (AFib), its symptoms, causes, risks, diagnosis, treatment options, and lifestyle changes to manage the condition and prevent complications.
