Understanding Atrial Fibrillation

Anatomically speaking, the human heart contains two upper chambers and two lower chambers. The upper chambers are called as the left and right atrium while the lower chambers are referred to as right ventricle and left ventricle.

When the two upper chambers of heart, collectively termed as atria, contract at an abnormally fast and uncontrollable rate in an irregular way, this is termed as atrial fibrillation.

According to a medical dictionary, fibrillation occurs when the normal rhythmic contractions of the cardiac atria are replaced by irregular contractions of the walls of the heart muscles.

Fibrillation is the most common form of arrhythmia. Arrhythmia is a collective term that refers to the problems with the speed and the rhythm of the heartbeat. These arrhythmias are caused by the heart’s electrical system.

We all know that the heart is made of 100% pure muscle. For the heart to beat, it involves different muscles. These muscles tighten in order to pump blood that will be supplied to the different parts of the body.

There are different kinds of fibrillation of the atria. These types include paroxysmal fibrillation of the atria, persistent fibrillation of the atria, and longstanding persistent fibrillation of the atria.

In paroxysmal fibrillation of the atria, there is an abnormality of the electrical signals and rapid heart rate then will stop on its own. A patient with paroxysmal fibrillation of the atria can experience mild or severe symptoms.

In persistent fibrillation of the atria, the atrial fibrillation only stops when the patient is already receiving treatment. On the other hand, longstanding persistent atrial fibrillation which is used to be called as permanent atrial fibrillation is an irreversible condition wherein the normal heart rhythm can’t be restored with the normal treatments.

Symptoms of atrial fibrillation usually include a fast heartbeat of 140 beats per minute. Aside from that there could also be other accompanying symptoms such as lightheadedness, dizziness, palpitations, and breathlessness. Hypotension or low blood pressure can also happen.

Some of the causes of atrial fibrillation include excessive caffeine consumption, smoking, and alcohol abuse. In order to keep your heart muscles healthy, it is important to engage in an active lifestyle by doing regular exercises every day.
