Atrial fibrillation (AFib) is an irregular and often rapid heartbeat that can cause poor blood flow to the body. AFib is considered a type of arrhythmia, or an abnormal heart rhythm. AFib can cause the heart to beat quickly, at least 100 beats per minute, or slowly, at fewer than 60 beats per minute. It can also cause an irregular or chaotic beat.
AFib: Fast or Slow?
The speed of AFib can vary from person to person, and even from episode to episode in the same person. Generally, AFib is classified as a fast or slow arrhythmia, depending on how fast the heart beats.
Fast AFib is defined as an arrhythmia in which the heart rate is greater than 100 beats per minute. It is also known as supraventricular tachycardia (SVT). People with fast AFib may experience symptoms such as palpitations, lightheadedness, and shortness of breath. Fast AFib can be dangerous if left untreated and can lead to stroke or other serious complications.
Slow AFib is defined as an arrhythmia where the heart rate is fewer than 60 beats per minute. It is also known as bradycardia. People with slow AFib may experience symptoms such as fatigue, dizziness, and shortness of breath. Slow AFib can also be dangerous and can lead to stroke or other serious complications.
Treating AFib
Fast and slow AFib can both be treated, depending on the underlying cause. Treatment options may include medications, lifestyle changes, or surgery. It is important to talk to your doctor to find the best treatment plan for you.
In conclusion, AFib can be either fast or slow. It is important to talk to your doctor to determine the best course of treatment.
