Atrial flutter can indeed be benign, and this is especially true if it is short in duration, and does not significantly affect the heart's ability to pump blood effectively. It is important to note that benign atrial flutter can still cause other symptoms, such as dizziness, palpitations, and chest pain. In order for it to be considered benign, a doctor must perform a physical examination, review medical history, and evaluate the patient's electrocardiogram (ECG). If the ECG shows normal sinus rhythms and no other abnormalities, then the atrial flutter is likely benign. However, if the ECG shows any type of irregular rhythms or other abnormalities, then the atrial flutter may be more serious and require medical attention. Therefore, it is important to speak to a doctor about any episodes of atrial flutter in order to determine the best treatment plan.
