Definition: A flutter is a form of a rapid heartbeat or arrhythmia. An Atrial flutter occurs when your atria beat faster than your ventricles, thus complicating your heart rhythm. Most people experience the feeling of a hast heart rate, shorness of breath, pressure in the chest, or feeling lightheaded but symptoms vary from person to person.
Example: A normal heart beat is 60 to 100 beats per minute and people with Atrial Flutter can have 250 to 300 heart beats per minute. It can be caused by a number of things including open-heart surgery, cornoary artery disease, and stress. Risk factors include heart disease, smoking, high blood pressure, heart valve conditions, lung disease, diet pills or certain other medications, stress or anxiety problems.
