Arrhythmias are abnormal heart rhythm and heart beat.
There are many types of arrhythmias.
They are categorized by some doctors by where they start in the heart (the atria, AV node, or the ventricles).
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.
The four main types of arrhythmia are:
1. Premature (Extra) Beats
Premature beats are the most frequent type of arrhythmia.
They are not harmful most of the time and often do not produce any symptoms.
When symptoms do happen, they normally feel like the fluttering in the chest or a feeling of a skipped heartbeat.
Most of the time, premature beats do not require treatment, particularly in healthy people.
2. Supra-ventricular Arrhythmias
Supra-ventricular arrhythmias are tachycardias (fast heart rates) that begin in the atria or atrioventricular (AV) node.
The AV node is a collection of cells sited between the atria and the ventricles.
Atrial Fibrillation
AF is the most frequent type of serious arrhythmia.
Signals may move throughout the atria in a rapid, disorganized way.
These cause the walls of the atria to quiver very fast (fibrillate) instead of beating normally.
As a result, the atria are not capable of pumping blood into the ventricles the way they should.
In AF, electrical signals can travel through the atria at a rate of more than 300 per minute.
Atrial Flutter
The heart's electrical signals spread through the atria in a fast and regular—instead of irregular—rhythm.
Paroxysmal Supra-ventricular Tachycardia
PSVT is a very fast heart rate that begins and ends suddenly.
PSVT happens because of disorders with the electrical connection between the atria and the ...
