AFib's Silent Threat: How an Irregular Heartbeat Can Change Lives

Atrial fibrillation, or AFib, is the most common type of heart arrhythmia. It disrupts normal blood flow, raising the risk of blood clots, stroke and heart failure. The condition is especially prevalent in adults over 65, though it can affect people of any age. AFib causes the heart to beat irregularly, sometimes too fast or too slow. A normal resting heart rate for adults is between 60 and 100 beats per minute. When the rhythm becomes erratic, symptoms may appear—though not everyone experiences them.

Common signs include heart palpitations, chest pain, fatigue, and shortness of breath. Some people also report dizziness, fainting, confusion, or a feeling that their heart is fluttering or skipping beats. However, AFib can sometimes go unnoticed, particularly if the heart corrects itself or symptoms are mild. Treatment depends on the severity and frequency of episodes. For those without symptoms or other heart issues, no immediate treatment may be needed. When care is required, doctors often prescribe medications to control heart rate and rhythm. Beta-blockers, calcium channel blockers, and sodium or potassium channel blockers are common choices. Blood thinners like rivaroxaban (Xarelto) and apixaban (Eliquis) help reduce clot risks. Lifestyle changes, such as a heart-healthy diet and regular exercise, also play a key role in managing the condition. Without proper care, AFib can lead to serious complications. Strokes and heart failure are the most frequent risks, but routine checkups and medication can lower these dangers significantly.

With the right medical support, many people with AFib continue to live full, active lives. Early diagnosis and consistent treatment help prevent complications and maintain long-term heart health. Regular monitoring remains essential for managing the condition effectively.
