Understanding Intermittent Atrial Fibrillation: 10 Common Symptoms

Introduction: A Closer Look at Intermittent Atrial Fibrillation

Atrial fibrillation (AFib) is a prevalent health issue affecting millions globally. The condition is particularly notorious for its episodic variant, intermittent atrial fibrillation, also recognized as paroxysmal atrial fibrillation. In essence, it’s a cardiac disorder characterized by abnormal electrical signals in the heart, leading to a rapid and irregular heartbeat.


The pattern of this irregular heartbeat can vary from patient to patient. Some may experience frequent episodes, while others may have weeks or even months in between. Due to the intermittent nature of the condition, it often goes undiagnosed until an episode occurs during a routine check-up or because a significant event brings the individual to the hospital.

The focus of this piece is to dissect the top 10 symptoms typically associated with intermittent atrial fibrillation. By shedding light on these signs, we aim to raise awareness and promote early detection, significantly improving the prognosis for individuals living with this condition.

Symptom 1: Unpredictable Heartbeat Patterns

Perhaps the most recognizable sign of intermittent atrial fibrillation is an irregular heartbeat, or arrhythmia. Individuals suffering from this condition often find themselves subject to rapid, unpredictable heartbeats. This is the defining characteristic of atrial fibrillation, and in the case of the intermittent variety, it occurs in episodic bursts rather than being a constant factor.

The erratic rhythm is not a mere quirk, it’s a manifestation of a serious cardiac event. The rhythm isn’t just faster, it’s also irregular, akin to a drummer who has lost the beat. During an episode, the heart can race, reaching more than 100 beats per minute, a stark contrast from the normal resting heart rate of 60 to 100 beats per minute for adults.

What makes this symptom particularly worrisome is that it can lead to the pooling of blood in the heart, increasing the risk of blood clot formation. If these clots travel to the brain, it could result in a stroke. Hence, it is crucial to recognize and manage this symptom early to prevent potentially life-threatening complications. (1)
