Fibrillation vs. Flutter
Fibrillation and flutter are both abnormal heart rhythms that can cause a variety of symptoms, including dizziness, chest pain, and shortness of breath. While both can be dangerous, they differ in their causes, symptoms, and treatments. Knowing the difference between the two can help you identify and treat any abnormal heart rhythm.
Cause of Fibrillation
Fibrillation is caused by disorganized electrical signals in the heart. These signals cause the heart to beat too quickly and irregularly. Fibrillation can be caused by a variety of factors, including damage to the heart muscle due to a heart attack or other medical conditions such as hypertension or diabetes.
Cause of Flutter
Flutter is caused by an abnormal electrical signal in the atria, the upper chambers of the heart. This signal causes the atria to beat too quickly and irregularly. Flutter can be caused by certain medical conditions, such as high blood pressure or thyroid disease, or by a heart attack.
Speed of Fibrillation vs. Flutter
Fibrillation is typically faster than flutter. The heart rate during fibrillation can range from 100-175 beats per minute, while the heart rate during flutter is usually between 100-140 beats per minute.
Symptoms of Fibrillation vs. Flutter
The symptoms of fibrillation and flutter are similar. Both can cause dizziness, chest pain, and shortness of breath. However, fibrillation may cause more pronounced symptoms such as chest pain that radiates to the arms or neck and a racing heart rate.
Treatment of Fibrillation vs. Flutter
The treatment of fibrillation and flutter depends on the underlying cause. In some cases, medications may be prescribed to help control the heart rate. In more serious cases, a procedure called cardioversion may be used to restore a normal heart rhythm. Cardioversion involves delivering a shock to the heart to reset its rhythm.
