The hearts electrical conduction is responsible for the contraction of the heart. Usually it start from the SA node going down to the AV and to the rest of the electrical conduction system.
Usually the electrical conduction can be seen with the use of the ECG machine. To see an overview of the hearts electrical conduction
Atrial Fibrillation is an aryhtmia or an abnormal conduction of the electrical conduction of the heart originating from the atrium. During this condition, the atrium contracs eratically and therefore does not provide enough blood to the ventricles.
The ventricles in turn, will be affected and will also contract irregulary if the situation is not treated.
People with atrial fibrillation my collapse, or may suffer weakness and other conditions. Treatment should be done. In most cases, people with atrial fibrillation if cannot be treated by medication will have to undergo a pacemaker implant.
Types of AF
There are several types, depending on how long the AF lasts.
- When atrial fibrillation is always present, it is referred to as chronic or permanent atrial fibrillation.
- When the arrhythmia is usually present, such that episodes of normal rhythm are infrequent or short-lived, it is referred to as persistent atrial fibrillation.
- When a normal heart rhythm is usually present but occasional episodes of the arrhythmia occur, the patient is said to have paroxysmal atrial fibrillation.
