Atrial fibrillation (AFib, AF) is a common type of heart rhythm abnormality with symptoms like dizziness, fainting, weakness, fatigue, shortness of breath. There are.
Atrial fibrillation, or AFib, is the most common type of irregular heartbeat.The electrical signal then leaves the AV node and travels to the ventricles.

The rate of impulses in the atria can range from 300 to 600 beats per minute.Instead of the impulse traveling in an orderly fashion through the heart, many impulses begin at the same time and spread through the atria, competing for a chance to travel through the AV node.
When the SA node fires an impulse, electrical activity spreads through the right and left atria, causing them to contract and force blood into the ventricles.Learn about atrial fibrillation (A fib), a rapid, irregular heart rhythm with symptoms like heart palpitations, chest pain, shortness of breath, and low blood pressure.They may spread throughout the atria in a rapid, disorganized way.
Atrial Fibrillation (AF), also abbreviated as AFib, is a kind of arrhythmia or irregular.The AV node limits the number of impulses that travel to the ventricles, but many impulses get through in a fast and disorganized manner.Atrial fibrillation it occurs most common among older people.
For people who have permanent AF, treatment can help control symptoms and prevent complications.
In some people, AF can cause chest pain or heart failure, especially if the heart rhythm is very rapid.Learn how to making living with atrial fibrillation (AFib) easier.
