Q

Atrial fibrillation

A

When the normal rhythmic contractions of the atria are replaced by rapid, uncontrolled twitching of the muscular heart wall. This causes an irregular and quivering action of the atria. Some of the increased electrical impulses reach the ventricles, and this makes them contract more rapidly and less efficiently than normal, producing an irregular rate of 80-180 beats per minute or more. Also known as A-fib.. most common type if tachycardia.
