Your heart works as a pump that takes blood to the lungs and then to rest of the body. To have this happen, an electrical system in the heart makes sure it contracts (squeezes) in an organized way.
Any interruption to the electrical impulses that aid the heart in contracting can up shot in arrhythmia. A person with a normal heart should have a heart beat rate in between 60-100 beats per minute when resting.
The more fit, healthy, and active a person is, the lower is his resting heart rate. Athletes, for example, usually have a resting heart rate below 60 beats per minute because their hearts are very efficient.
A number of elements can cause the heart to work in an unorganized.
Arrhythmia can occur due to blocked electrical signals, abnormal electrical signal pathways, or irritable heart cells that send signals abnormally.
Common causes of arrhythmia (abnormal heart rhythms) are:
Some arrhythmias are caused by genetic factors. In such cases, the arrhythmia is called as a genetically-linked arrhythmia.
Genetic arrhythmias are considered to be the result of either an inherited characteristic or some sort of genetic mutation.
Coronary artery spasm is a temporary discomfort or pain caused by a spasm or constriction in the coronary arteries. This can block the blood supply to your heart muscle.
Spasms can be very minor or severe in intensity, and can sometimes completely block your coronary artery. This can eventually cause disturbed cardiac rhythms (arrhythmias).
Sometimes, the cause of arrhythmias is not clear.
A healthy and fit person generally does not suffer from long-term arrhythmia unless there is an external trigger. These triggers could be drug abuse, an electric shock etc.
