Atrial fibrillation (AFib) represents a significant health concern in the field of cardiology. It is essential to grasp the nuances of AFib within the context of steroid use, as understanding the condition can influence both clinical practice and patient outcomes. This section aims to present a comprehensive overview of AFib, setting the stage for its potential interactions with steroid usage.

Definition and Types

Atrial fibrillation is characterized by an irregular and often rapid heart rate. This arrhythmia results from disorganized electrical signals in the heart's upper chambers, leading to ineffective atrial contractions. The irregular rhythm can reduce the heart's efficiency and increase the risk of stroke.

AFib can be classified into several types:

Paroxysmal AFib: Episodes are sporadic and typically resolve on their own within seven days.
Persistent AFib: Episodes last longer than seven days and may require treatment to restore normal rhythm.
Long-standing Persistent AFib: The condition continuously lasts for a year or more.
Permanent AFib: Despite treatment, the heart remains in AFib.

Understanding these definitions is crucial because the type of AFib influences treatment approaches and outcomes.

Symptoms and Diagnosis

Individuals with AFib may experience a range of symptoms, though some may be asymptomatic. Common symptoms include:

Palpitations or a fluttering sensation in the chest
Dizziness or lightheadedness
Shortness of breath
Fatigue

Diagnosis typically involves a physical examination and diagnostic tests, including an electrocardiogram (ECG). The ECG records the electrical activity of the heart, revealing AFib's characteristic patterns. Additionally, healthcare providers may conduct blood tests and imaging studies, such as echocardiograms, to evaluate underlying conditions contributing to AFib.

Prevalence and Risk Factors

AFib is prevalent globally, with an increasing incidence as the population ages. Factors contributing to its development include:

Age: The likelihood of developing AFib rises significantly for individuals over 65 years old.
