Atrial fibrillation/flutter is a heart rhythm disorder (arrhythmia. It usually involves a rapid heart rate, in which the upper heart chambers (atria) are stimulated to contract in a very disorganized and abnormal manner.

Atrial fibrillation and flutter are abnormal heart rhythms in which the atria, or upper chambers of the heart, are out of sync with the ventricles, or lower chambers of the heart. In atrial fibrillation, the atria " quiver " chaotically and the ventricles beat irregularly.

Heart failure, also called congestive heart failure, is a life-threatening condition in which the heart can no longer pump enough blood to the rest of the body.
|
|
"Heart failure" is a broad term- often used inter-changeably with "congestive heart failure" (CHF)- to describe the heart's inability to consistently pump enough blood to the body's organs and tissues. Heart failure occurs either from a structural or a functional abnormality.
|
|
Heart failure is a condition in which the heart has lost the ability to pump enough blood to the body ' s tissues. With too little blood being delivered, the organs and other tissues do not receive enough oxygen and nutrients to function properly.

Low blood pressure, or hypotension, occurs when blood pressure during and after each heart beat is much lower than usual. This means the heart, brain, and other parts of the body do not get enough blood. Dizziness or lightheadedness can result. See also: Blood pressure

Hypotension is the medical term for low blood pressure. The pressure of the blood in the arteries rises and falls as the heart and muscles handle demands of daily living, such as exercise , sleep and stress .
