Atrial fibrillation (AFib) is a common irregular heart rhythm, a type of arrhythmia, that can be difficult to diagnose and treat. If left untreated, AFib can lead to more serious medical issues, like congestive heart failure and stroke. “What happens with atrial fibrillation is the top part of the heart, it’s on its own dance,” said Dr. David Lam, cardiologist, Swedish Heart and Vascular Institute. “It’s on its own song. But the bottom part doesn’t know that song, so they’re just going off rhythm." While symptoms of anxiety can be similar, AFib typically causes more palpitations or irregular rhythms for a longer period of time. Patients can also feel fatigued and short of breath. “The best thing to do is we need to get a diagnosis,” Dr. Lam said. “We need to know: is it just stress related? Is it too much caffeine that day? Or is it atrial fibrillation?” If AFib is suspected, a doctor will recommend an echocardiogram for diagnosis. Diagnosing and treating AFib promptly can prevent issues like stroke and heart failure. “There are pretty serious complications that we want to make sure are treated,” Dr. Lam said. Lifestyle changes can help you prevent AFib. These include maintaining a healthy weight, exercising 30 minutes per day, reducing alcohol consumption and focusing on a good night’s sleep. “Sometimes sleep disorders, whether you’re snoring, or your bed partner says you’re snoring, or you’re not breathing well at night, those can also be signs that something’s going on,” Dr. Lam said. The Swedish AFib Clinic provides comprehensive care to patients with AFib. This involves a team-based approach with an emphasis on improving quality of life and wellness with personalized treatment.
