Atrial Bigeminy is a harmless, benign rhythm. It is frequently an incidental finding and is usually asymptomatic. No further cardiac investigations are indicated as most people with this rhythm do not have organic heart disease (although in those with heart disease, it seen).
Atrial fibrillation, or A-Fib, is a common arrhythmia in which the heart's upper chambers (the atria) quiver rather than contract (squeeze) normally, sometimes as many as 600 times per minute. This causes the heart's lower chambers (the ventricles) to contract out of rhythm and faster than normal. Without treatment, A-Fib can lead to other serious heart problems, like enlargement of the heart (called cardiomyopathy) and heart failure (when the heart cannot fill or pump enough blood to meet the body's needs).
