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.
As the therapist placed me in the electric wheelchair, cinching the seat belt around my waist, my legs kicked with a chaotic rhythm
of spasms, excitement and nervousness.
(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.
DURING A YEAR WHEN THE hearts of local investors beat to the chaotic rhythm
of the New York Stock Exchange, fiscal 1999 proved a time for setting new records, staging cardiac comebacks and selling or moving a few home-grown public giants out of Arkansas.
VF is a chaotic rhythm
of the heart, in which the ventricles quiver, but do not pump blood.
This may result from ventricular tachycardia and ventricular fibrillation (an extremely rapid, chaotic rhythm
during which the heart quivers).
That's because the chaotic rhythm
of a heart in AFib allows blood to pool in the atria (the heart's upper chambers), which can lead to the formation of a blood clot that can break free of the heart, travel to the brain, and block blood.
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.
