Atrial Fibrillation
Atrial fibrillation (AFib) is a prevalent heart condition in Ireland, characterized by an irregular and often rapid heartbeat. This irregularity arises when the heart's upper chambers (atria) experience chaotic electrical signals, leading to an uncoordinated and inefficient heart rhythm.
Atrial Fibrillation (AFib) is a common type of irregular heartbeat, or arrhythmia, where the heart’s upper chambers (atria) beat erratically and out of coordination with the lower chambers (ventricles).
It is a significant health concern that requires attention and management. By understanding its symptoms, causes, and treatment options, and by utilizing available resources, individuals can effectively manage AFib and maintain a good quality of life.
Atrial fibrillation is a common but serious heart condition that requires proper management to prevent complications like stroke and heart failure. Early diagnosis and a combination of medical treatment and lifestyle changes can significantly improve outcomes.

What is Atrial Fibrillation? Atrial Fibrillation (AFib) is a common type of irregular heartbeat, or arrhythmia, where the heart’s upper chambers (atria) beat erratically and out of coordination with the lower chambers (ventricles). This can lead to inefficient blood flow and may increase the risk of stroke, heart failure, and other heart-related complications.
-
AFib can occur due to various causes, including:
High blood pressure (hypertension)
Heart disease or heart valve problems
Diabetes
Sleep apnea
Stress or excessive alcohol consumption
Age (older adults are at higher risk)
Family history of AFib
-
While some individuals with AFib remain asymptomatic, others may experience:
Heart palpitations: sensations of a racing, fluttering, or pounding heart.
Fatigue and reduced ability to engage in physical activities.
Shortness of breath.
Dizziness or lightheadedness.
Chest discomfort.
It's important to note that AFib can be intermittent or persistent. If you notice any of these symptoms or detect an irregular pulse, it's advisable to consult a healthcare professional.
-
Early detection of AFib is crucial to prevent complications like stroke. Diagnosis typically involves:
Pulse Check: Assessing your pulse can indicate irregularities. The Irish Heart Foundation provides resources on how to check your pulse effectively.
Electrocardiogram (ECG): A test that records the heart's electrical activity to confirm AFib.
Additional Tests: Depending on individual circumstances, further evaluations such as echocardiograms, chest X-rays, or blood tests might be recommended
-
Managing AFib aims to restore normal heart rhythm, control heart rate, and reduce stroke risk. Treatment strategies may include:
Medications:
Anti-arrhythmics: To maintain a regular heart rhythm.
Rate control drugs: To manage heart rate.
Anticoagulants: To prevent blood clots and reduce stroke risk.
Cardioversion: A procedure where a controlled electric shock is delivered to the heart to restore normal rhythm.
Catheter Ablation: A minimally invasive procedure that destroys the areas of the heart causing abnormal rhythms.
Pacemaker Installation: In cases where other treatments are ineffective, a pacemaker may be implanted to regulate the heartbeat.
