Atrial Fibrillation: Understanding Your Risk and When to Seek Care
Atrial fibrillation (AFib) is one of the most common heart rhythm conditions we see in the emergency room at the Oklahoma Heart Hospital. For many patients, it begins with a sensation that is hard to ignore: a racing heartbeat, a flutter in the chest, or the feeling that something is suddenly off.
AFib is often manageable, but it still requires evaluation. While symptoms can feel alarming in the moment, they do not always indicate immediate danger. However, it should not be brushed aside or left unaddressed, as untreated atrial fibrillation increases the risk of serious complications, including stroke.
Knowing which symptoms require urgent attention, understanding the factors that increase the likelihood of AFib, and learning how to manage the condition helps patients make informed treatment choices and take meaningful steps to support their long-term heart health.
Who is at risk for AFib?
Atrial fibrillation is more likely to develop in patients with certain underlying conditions, but it rarely results from a single factor. In most cases, it reflects a combination of influences that affect how the heart’s electrical system functions over time.
Certain medical conditions are closely associated with AFib, including:
- high blood pressure
- heart disease
- sleep apnea
- diabetes
These conditions can alter the heart’s structure and electrical activity, which makes irregular rhythms more likely.
Age also plays a role, especially after 65. As the heart and vascular system age, the likelihood of developing AFib increases.
Lifestyle factors can also influence how AFib develops and progresses. Alcohol use, excess weight, poor sleep, and unmanaged stress can all contribute to how often AFib occurs and how severe episodes may become. These factors often overlap with underlying medical conditions, which further increases overall risk.
For some patients, family history may also play a role, even when other risk factors are less apparent.
What AFib symptoms may look and feel like
Atrial fibrillation does not present the same way for every patient, and symptoms are not always consistent from one episode to the next. Some people notice a clear change in their heartbeat, described as rapid, irregular, or off-beat. Others notice a more general shift, such as fatigue, shortness of breath, dizziness, or a reduced ability to stay active.
In some cases, symptoms come and go, which makes them easy to overlook. Patients may adjust to how they feel over time, especially when changes are gradual.
Even when symptoms are mild, new or recurring changes should be evaluated. A pattern of symptoms, even if intermittent, provides important insight into how the heart is functioning and whether further assessment is needed, particularly because untreated AFib can increase the risk of complications.
Treatment and management of AFib
Management of AFib depends on the individual, including symptom severity, underlying risk factors, and overall heart health. Treatment often focuses on improving lifestyle, controlling heart rhythm, and reducing the risk of complications, particularly stroke.
Some patients can manage AFib with medication, while others may benefit from procedures like catheter ablation.
For many patients, AFib is managed over time rather than resolved with a single intervention. Addressing underlying conditions, maintaining a healthy weight, limiting alcohol intake, managing stress, and treating sleep apnea can help stabilize heart rhythm and reduce the risk of future episodes.
Long-term care often includes a combination of medical treatment and lifestyle adjustments.
When to seek care and what to expect
If you notice new or recurring symptoms, it is important to see a healthcare provider. Many cases of AFib can be assessed in a clinic setting, particularly if symptoms are mild or have occurred before. However, symptoms like chest pain, fainting, or severe shortness of breath should always be treated as an emergency.
Timely evaluation and ongoing management are important not only for symptom control but also for reducing the risk of complications that can develop when AFib is left untreated. Once AFib is identified, the next step is determining the best approach to care.
At the Heart Rhythm Institute at the Oklahoma Heart Hospital, we specialize in evaluating and treating AFib and other heart rhythm disorders by focusing on managing symptoms, reducing risk, and supporting long-term heart health.
