What is arrhythmia
Arrhythmia is the disturbances in the electrical conducting system of the heart muscles creating an irregular heart rhythm.
In the normal electrical conduction the impulse pass from the SINO ATRIAL node (SA node) located on the right atrium to the atria chambers to contract. Then impulses passes to the ATRIOVENTRICULAR node (AV node) located in between atrium and ventricles. Now from AV node impulses travel to the ventricles to contract.
This electrical conduction makes the heart to contract to pump blood. Any disturbances in this electrical impulse distribution will cause arrhythmia (unbalanced or uncharacteristic heartbeat).
The increase in the heart beat is called as TACHYCARDIA. The decrease in the heart rate is called as BRADYCARDIA.
Any fluctuating or irregular heart beat is called as FIBRILLATION (ATRIAL OR VENTRICULAR FIBRILLAITONS).
The normal heart beat range is 70 to 80 beats per minute. In TACHYCARDIA the heart beat rate is more than 100 beats per minute. In BRADYCARDIA the heart beat is less than 60 beats per minute.
