Heart conditions are certainly among the most worrisome maladies, and sadly they are also some of the most common in the developed world. A healthy heart has a regular rhythm, and will beat at approximately 60 to 100 beats a minute when at rest. The presence of atrial fibrilation means that the heart's rhythm becomes irregular. This is sometimes accompanied by its beat pattern becoming abnormally fast (known as palpitations).
This impaired functioning of the heart can lead to symptoms such as shortness of breath, tiredness, dizziness and chest pains. The palpitations that sometimes accompany AF can be felt as a thumping heart. Some sufferers however have very mild or even no symptoms and are only diagnosed by chance.
A healthy heart contracts and relaxes rhythmically, forcing blood into the body and drawing in a fresh supply with each cycle. AF is a disruption in this process whereby the upper chambers of the organ contract in a fast, random manner. The heart cannot relax properly and consequently it's efficiency is impaired.
The cause of the condition is not fully understood, but it involves improper functioning if the heart's electrical signals. When these signals fire suddenly and randomly, they override the organ's inbuilt pacemaker and cause it to beat irregularly. The exact way in which this occurs varies from patient to patient.
In some patients, AF is very short-term and can come and go within a day or two. Other cases can last a week or more, while others can extend to over a year. Still other cases are more or less permanent and call for more significant intervention.
Overall, it is more prevalent in men than women, and in older people than the young (it can certainly affect young people, but this is rare). It is also more likely to be seen in people with existing heart trouble and other conditions such as arterial disease and high blood pressure. Lifestyle can also play a part, with excessive smoking and drinking thought to be triggers for the condition.
Although not typically life-threatening, it can be a source of considerable distress and patients can benefit greatly from attention. Primary interventions include specialist drugs, electrical stimulus and in some cases, pacemaker fitment. These interventions, when successful, can provide patients with considerable relief and a welcome boost to their quality of life.
