Atrial flutter (AFL) is a type of abnormal heart rhythm that occurs when the heart's upper chambers (atria) beat too quickly. It is similar to atrial fibrillation but the two conditions are not the same. AFL is typically seen in middle-aged and older adults, and typically results in palpitations and shortness of breath. While AFL may be caused by various factors, such as underlying heart disease, it is not known whether the condition is getting worse over time.
Risk Factors for Atrial Flutter
Atrial flutter is more common in people who have existing heart conditions, such as coronary artery disease, high blood pressure, and congestive heart failure. Other risk factors for atrial flutter include being male, age 65 or older, having a history of smoking, and having a family history of atrial fibrillation.
Diagnosis and Treatment of Atrial Flutter
Atrial flutter is typically diagnosed with an electrocardiogram (ECG). In some cases, additional tests may be necessary, such as an echocardiogram or a Holter monitor. Treatment for atrial flutter typically involves medications, such as beta-blockers, calcium channel blockers, and anticoagulants. In some cases, ablation (or a procedure to destroy the abnormal electrical pathways) may be recommended.
Is Atrial Flutter Getting Worse Over Time?
At this time, there is no clear answer to this question. There have been studies that suggest that the incidence of atrial flutter is increasing, but it is difficult to draw definitive conclusions. It is possible that the increasing prevalence of underlying heart conditions is contributing to the higher rate of atrial flutter, but more research is needed.
