Millions of people experience irregular heartbeats, called arrhythmias, at some point in their lives. Most of the time, they are harmless and happen in healthy people free of heart diseases. However, some abnormal heart rhythms can be serious or even life threating. Having other types of Heart Diseases can also increase the risk of arrhythmias.
Over the past decade, molecular genetic research has established a link between a number of inherited, lethal cardiac arrhythmias and mutations in genes encoding for ion channels or other membrane components.
These purely electrical heart diseases may manifest at any age, and are responsible for a large number of sudden unexpected deaths in otherwise healthy, young individuals and even children.
Abnormal heart rhythms (arrhythmias) are caused by problems with the electrical system that regulates steady heartbeat. The heart rate may be too slow or too fast; it may stay steady or become chaotic (irregular or disorganized). Some arrhythmias are very dangerous and cause sudden cardiac death, while others may be bothersome but not life threatening.
