Hello, I'm a healthcare professional with experience in cardiology. I can provide you with information regarding atrial fibrillation. Atrial fibrillation, often referred to as AFib, is a common heart rhythm disorder that can indeed come and go. This means that it can be paroxysmal, which is a medical term for an episode that starts suddenly and lasts for a period of time before it resolves on its own. These episodes can vary in frequency and duration, ranging from a few minutes to several hours or even days. However, it's important to note that the presence of intermittent AFib doesn't make it any less serious. Even if it's not constantly present, it can still lead to complications such as stroke, heart failure, or other cardiovascular issues. It's crucial for individuals experiencing symptoms of AFib to seek medical attention to determine the best course of action for their specific situation. read more >>
