"Aflutter" is a medical term used to describe an abnormal heart rhythm, specifically a type of arrhythmia called atrial flutter. In atrial flutter, the heart's upper chambers (atria) beat too quickly, regularly and out of sync with the lower chambers (ventricles) which can lead to reduced cardiac output and other complications.
Atrial flutter can cause symptoms such as palpitations, shortness of breath, fatigue, dizziness, and fainting. Treatment options for atrial flutter may include medication, cardioversion (an electrical shock to restore normal heart rhythm), catheter ablation, and in some cases surgery.
It's important to note that the term "aflutter" can also be used in non-medical contexts to describe a state of excitement or nervousness.
