Atrial fibrillation (AFib) occurs when rapid, disorganized electrical signals cause the heart’s two upper chambers (the atria) to contract at a fast and irregular pace—or fibrillate. This can lead to blood pooling in the atria and not passing smoothly to the heart’s two lower chambers (the ventricles). This ultimately leads to a disruption in the heart’s normal electrical harmony.

Sigma Nursing answeredThe symptoms of occasional atrial fibrillation can range from no symptoms at all to chest pain and shortness of breath, lowered blood pressure, feelings of lightheadedness, weakness, confusion, and palpitations. Palpitations are usually uncomfortable and feel like your heart is jumping around in your chest. It is important to contact your doctor or seek emergency medical care immediately if you are experiencing chest pain. This is also a symptom of a heart attack. Otherwise, let your doctor know about your symptoms of occasional atrial fibrillation.

Greenville Health System answeredSee All 2 AnswersIf you have atrial fibrillation, you may experience heart palpitations. Heart palpitations are an uncomfortable but common occurrence. Most of the time, heart palpitations are not serious. However, if you have an arrhythmia such as atrial fibrillation, you need to see a doctor to get a medical evaluation. With palpitations, you feel like your heart is fluttering, pounding or racing inside your chest. You might think your heart is adding extra beats or even skipping beats. If you have a rapid heart rate (100 beats a minute or higher), it is referred to as tachycardia. If you have a slow heart rate (less than 60 beats a minute), it's called bradycardia. In addition, if you have heart valve problems, low potassium or heart disease, or if you have a high risk for heart disease, call your doctor immediately if you have heart palpitations.

Portsmouth Regional Hospital answeredSee All 3 AnswersYes, you should talk to your doctor about your atrial fibrillation symptoms. Untreated atrial fibrillation can have serious complications, such as stroke or heart failure. If your symptoms are severe, such as chest pain or trouble breathing, you should go to an emergency room rather than wait for an appointment.

Dr. Michael Roizen, MD , Internal Medicine, answeredSee All 3 AnswersYES! You would think it would be hard to miss if your heart suddenly started beating like it was doing an extended jazz drum solo, but you may not be bothered. Atrial fibrillation may not cause noticeable symptoms in everyone. In fact, many patients find out that they have atrial fibrillation during an annual physical exam when a doctor conducts a routine physical or performs an electrocardiogram (ECG). -
