Why do hearts flutter?

Fast heart rate. When someone's heart rate is fast (more than 100 beats per minute), it can feel like heart fluttering. It can have different causes from very benign, no needing treatment to life threatening. The term 'atrial flutter' describes an abnormally fast rhythm where the electricity in the upper chamber of the heart goes round and round a large circle.
Most common. Reason is premature atrial or ventricular contractions which are generally benign but other arrhythmias not so much.
Many reasons. Usually for various reasons, the rhythm of the heart changes and the patient feels a flutter. Typical reasons are supraventricular or arrhythmias from above the ventricle. These include atrial flutter and fibrillation.

Atrial Flutter. Atrial flutter is a special type of rhythm disorder in which there is an extra pathway in the upper chamber of the heart that cycles and stimulates the lower chambers of the heart. The rate can be quite rapid, or can be more controlled depending on how the lower chambers respond to the extra signals. This condition is treated with medications, cardioversion, and/or ablation of the pathway. Read more...
