This book describes Abnormal Slow Heart Beats, Diagnosis and Treatment of Bradycardias and Related Diseases
Brady-arrhythmia is an abnormal slow heart rhythm and heart beat.
There are many types of Brady-arrhythmias.
They are categorized by some doctors by where they start in the heart (the atria, AV node, or the ventricles).
An arrhythmia is a disorder with the rate or rhythm of the heartbeat.
When an arrhythmia occurs, the heart can beat too fast, too slow, or with an irregular rhythm.
Tachycardia is a heartbeat that is too fast.
Bradycardia is a heartbeat that is too slow.
Most arrhythmias are harmless, but some can be serious or even life threatening.
Brady-arrhythmias happen if the heart rate is slower than normal.
If the heart rate is too slow, not enough blood enters the brain.
This can induce the patient to faint.
In adults, a heart rate slower than 60 beats per minute is called a brady-arrhythmia.
Certain people normally have slow heart rates, particularly people who are very physically fit.
For them, a heartbeat slower than 60 beats per minute is not riskier and does not induce symptoms.
But in other people, severe diseases or other disorders may produce brady-arrhythmias.
Brady-arrhythmias can be produced by:
2.Disorders that harm or change the heart's electrical activity, such as an under-active thyroid gland or aging
3.An imbalance of chemicals or other substances in the blood, such as potassium
4.Medicines such as beta blockers, calcium channel blockers, some anti-arrhythmia medicines, and digoxin
Sick sinus syndrome:
Irregular electrical impulses produced by the SA node produce a slower-than-normal heart rate (occasionally alternating with rapid heart rates if the electrical impulses switch to a high rate).
Brady-arrhythmias can have symptoms that are more generalized, ...
