Atrial Fibrillation And Ectopic Heartbeat: Are They Dangerous?

Atrial fibrillation (AFib) is a type of irregular heartbeat that can become dangerous if it persists for more than 48 hours. One of the primary concerns with prolonged AFib is the increased risk of blood clot formation, also known as thromboembolism. These clots, or emboli, can dislodge at any time and travel through the bloodstream, potentially causing life-threatening blockages in vital organs.

Potential Complications Of Long-Lasting Atrial Fibrillation

When an embolus breaks free, it may lead to serious conditions such as stroke (brain embolism), pulmonary embolism (blockage in the lung arteries), or even cardiovascular events like myocardial infarction (heart attack). Peripheral artery embolism, especially in the lower limbs, is another possible complication that can result in tissue damage or loss.

Impact On Heart Structure And Function

Extended episodes of atrial fibrillation can cause structural changes in the heart, particularly left atrial enlargement. This can further deteriorate the condition of patients with pre-existing heart diseases and may eventually lead to heart failure. The longer the arrhythmia lasts, the greater the risk of permanent cardiac damage.

Recommended Treatments And Prevention

Anticoagulant therapy is typically recommended for patients whose AFib lasts beyond 48 hours to reduce the risk of clot formation. In certain cases, doctors may also consider radiofrequency ablation, a minimally invasive procedure that targets and corrects the abnormal electrical pathways in the heart, offering a potential long-term solution for managing atrial fibrillation.
