Another type of treatment is called cardioversion, and it involves the application of a mild electric shock to the heart to stop the chaotic rhythm and return the heart to its normal pace.
(178) McKenzie Leiper offers tenacious optimism, uncovering stories of women who have carved their own rewarding, if not always conventional, career paths, who have achieved fulfilling lives, and choreographed intricate timetables despite the sometimes chaotic rhythm of children's needs and greedy institutions.
Atrial Fibrillation is a common and devastating cardiac rhythm disorder in which the heart's upper chambers beat extremely fast and in an apparent chaotic rhythm. Symptoms include palpitations, dizziness and shortness of breath.
When the heart stops beating, or flutters ineffectively in a chaotic rhythm, it starves the brain, the heart and other organs of blood.
SCA occurs when the heart quivers in a chaotic rhythm called ventricular fibrillation (VF).
The muscle dies, and electrical instability takes place in the form of a chaotic rhythm that is very rapid, called ventricular fibrillation.

Whereas atrial flutter is caused by an electrical current circling around and around (until it is finally interrupted), afib is a more chaotic rhythm. These characteristics are reflected by their appearances on a 12-lead electrocardiogram (EKG): Atrial flutter exhibits repeated identical little wavelets, whereas afib is completely random.
