Atrial Fibrillation Awareness Month: Know the Signs, Protect Your Heart

Every September, Atrial Fibrillation (AFib) Awareness Month draws attention to one of the most common heart rhythm conditions. AFib can feel overwhelming when you first hear about it, but the good news is that it can be managed with the right care. At Holy Cross Health, we want patients to understand what AFib is, how it shows up in everyday life, and what steps can be taken to protect heart health. 

How AFib Can Affect You 

AFib does not always look the same for everyone. Some people feel noticeable changes in their body, while others may not experience any symptoms at all. One of the most common signs is fatigue. When the heart is not pumping efficiently, the body receives less oxygen-rich blood. Even simple activities like grocery shopping or walking around the house may feel unusually tiring. Dizziness or fainting can also occur. Irregular rhythms may reduce blood flow to the brain, which can lead to lightheadedness or, in some cases, a brief loss of consciousness.  

For many people, shortness of breath is another clue. Physical activity that once felt easy may suddenly leave you feeling winded. Some individuals experience chest discomfort, which may feel like tightness or pressure. Because chest pain can be linked to other heart conditions, it is always important to have it evaluated by a doctor.

Finally, some patients have no symptoms at all. In these cases, AFib may only be detected during a routine exam or while testing for another condition. This is why regular check-ups are so valuable. 

How AFib Is Diagnosed 
If AFib is suspected, doctors use a series of tests to confirm the condition and determine the best treatment plan. The process often begins with a physical exam and review of medical history. An electrocardiogram (ECG or EKG) is the most common test, showing the heart’s electrical activity and identifying the irregular rhythm that defines AFib.
Doctors may also order laboratory tests to check for underlying causes, including thyroid function or other blood imbalances. Imaging tests, such as an echocardiogram, transesophageal echocardiogram (TEE), or chest X-ray, provide a closer look at how the heart is working.

Sometimes, short tests do not capture irregular rhythms. In these cases, doctors may use loop recorders or event monitors that track heart activity over a longer period of time. 

Why AFib Matters 

AFib is not always immediately dangerous, but it should never be ignored. Without treatment, it can lead to serious complications. One of the most concerning risks is stroke. AFib can cause blood to pool in the heart, leading to clot formation. If a clot travels to the brain, it can block blood flow and cause a stroke.

Heart failure is another risk, as the constant irregular rhythm may weaken the heart over time. AFib can also cause reduced cardiac output, meaning the body is not receiving enough blood and oxygen. This may leave patients feeling weak, dizzy, or faint.

Finally, AFib can cause systemic embolism, when a blood clot blocks blood flow to other vital organs.  

Understanding these risks highlights the importance of timely diagnosis and management.

Treatment Options 

Treatment for AFib is tailored to each patient. The main goals are to control the heart rate, restore or maintain a normal rhythm, reduce the risk of stroke, and improve quality of life. Some patients may be treated with medications that slow the heart rate or help the heart maintain a steady rhythm. Others may need procedures to correct the irregular heartbeat, such as cardioversion or catheter ablation. In some cases, doctors may recommend blood thinners to prevent clots and lower stroke risk.

Lifestyle changes also play a role. Limiting alcohol and caffeine, eating a heart-healthy diet, exercising regularly, managing stress, and quitting smoking can all support better outcomes. Regular follow-ups help patients and care teams track progress and adjust treatment as needed.
