Can you have a regular rhythm with AFIB?

As a medical professional with expertise in cardiology, I can provide you with an informed response to your question regarding atrial fibrillation (AFIB) and regular rhythm. Atrial fibrillation is a type of irregular heartbeat, characterized by rapid and irregular contractions of the atria, the upper chambers of the heart. This condition can lead to a lack of a consistent rhythm, which is why it's often described as an "irregular irregular rhythm." However, it's important to note that the ventricular rate in AFIB can sometimes be regular, especially if managed with medications or other treatments that control the heart rate. In some cases, individuals with AFIB might experience episodes where their heart rhythm appears regular for a period of time. This could be due to the use of rate-controlling medications, or it could be a temporary respite from the irregular rhythm. However, the underlying atrial fibrillation is still present, and the atria are not contracting in a coordinated, regular manner. It's also worth mentioning that there are different types of AFIB, including paroxysmal, persistent, long-standing persistent, and permanent. Each type has its own characteristics and treatment approaches. In summary, while it's possible for someone with AFIB to have a regular rhythm at times, this does not mean that the AFIB has been cured or that the atria are functioning normally. Regular monitoring and management by a healthcare provider are crucial for individuals with this condition.

The combination of atrial fibrillation with a regular rhythm (��regularised AF��) indicates that none of the atrial impulses are conducted to the ventricles, i.e. complete heart block is present. The narrow complex rhythm is therefore a junctional escape rhythm.
