Arrhythmias are abnormal rhythms of the heart than
can cause the heart to pump less effectively.
Arrhythmia occurs
- when the hearts natural pacemaker develops an abnormal rate or rhythm
- when the normal conduction path is interrupted
- when another part of the heart takes over as pacemaker.
- These problems can produce a heartbeat that is too slow or too fast.
Symptoms
- fatigue
- dizziness
- lightheadedness
- fainting spells
- palpitations or rapid heart action.

| When rapid heartbeating arises from the ventricles, a
life-threatening situation can arise. Sometimes blood clots can form during atrial
fibrillation, where the two small upper chambers of the heart, the atria, quiver instead
of beating effectively. If a piece of the blood clot in the atria becomes lodged in an
artery in the brain, a stroke (brain attack) results. |

Pacemakers
Most of these symptoms can be corrected with an electronic pacemaker.
Pacemakers are battery-operated devices that help your heart beat in a regular rhythm.
Some are permanent, installed internally, and some are temporary, installed externally.
Most have a sensing device that turns itself off when your heartbeat is above a certain
level.
Many of the inconveniences associated with early pacemakers have
decreased, and most people feel that their quality of life is much better with a
pacemaker. Less invasive procedures are available to install them, and the technology used
in pacemakers has dramatically improved. Your doctor can discuss the different types of
pacemakers and the responsibilities associated with them.
Need A Physician?
Many patients currently suffering
from arrhythmia are not under the care of a cardiologist. If you have questions about
arrhythmia, or feel that you may have a heart condition, consult your primary care
physician. If necessary, your doctor may refer you to a cardiologist.
If you are concerned about your blood pressure, contact your
physician. If you need a physician, call 1-888-749-DrDr or click here.
