What is characterized by atrial fibrillation at a rate of less than 100 bpm?

• A. Paroxysmal supraventricular tachycardia
• B. Benign atrial finding
• C. Premature junctional complex
• D. Brief ventricular tachycardia

Answer: (B)

Atrial fibrillation is a type of irregular heartbeat where the atria experience chaotic electrical activity. When atrial fibrillation occurs at a rate of less than 100 beats per minute, it is diagnosed as "controlled atrial fibrillation." This condition is often viewed as a benign finding, especially in patients who have well-managed heart rates and no significant underlying heart conditions. The low rate indicates less cardiac strain compared to an uncontrolled situation where the heart rate exceeds 100 bpm, which can lead to more noticeable symptoms and complications. In a clinical context, if a patient presents with atrial fibrillation at a controlled rate, it may not warrant aggressive intervention and might require only monitoring and routine management. This makes it a benign finding when compared to other conditions that either present with higher heart rates or have more serious implications on cardiac function. Recognizing atrial fibrillation at a controlled rate as a benign finding helps clinicians determine the appropriate level of management for their patients.
