Atrial Fibrillation Series:
When you receive your atrial fibrillation diagnosis, you may be told you have one of the following types described below. Although the pathology (characteristics) of the disease can be similar, the duration of time that the heart spends in fibrillation can vary greatly. Importantly, the longer the heart spends in atrial fibrillation, the greater the risk of stroke. That being said, even if you do not have ANY symptoms, all patients with any type of atrial fibrillation have a significantly greater risk for stroke and should continue the advice, medication regimen, and lifestyle changes recommended by their healthcare provider for stroke-reduction.
Normally, electrical signals from the heart’s natural pacemaker, the sinus node, control the contractions of cardiac muscle. These impulses are rhythmic, steady and controlled.
Atrial fibrillation is caused by disorganized and chaotic electrical signals from different parts of the atria, the upper chambers of the heart. This results in an irregular and often rapid heart rhythm since each part of the atria emits electrical activity independently and result in the ventricles being bombarded with electrical impulses.
These abnormal electrical impulses can be caused by damage to the heart, often from other types of cardiac diseases. Coronary artery disease, heart failure, cardiomyopathy and hypertension can all increase your risk for atrial fibrillation. Other factors like diabetes, thyroid abnormalities, lung abnormalities or excessive alcohol intake, can also trigger atrial fibrillation.
Symptoms from atrial fibrillation can vary from person-to-person; no two people will have identical symptoms. Below is a list of some the most common symptoms for atrial fibrillation. Use this as a guide for symptoms, but also seek out professional help and assistance for any symptoms you may develop.
