|Cardiac arrhythmias, also commonly called arrhythmias, are irregularities of the heart beat. For the most part, the normal, constant rhythm of the heartbeat that ensures essential blood flow throughout the body goes unnoticed.
But for some people, problems arise as the electrical impulses that synchronize the heart beat donít function properly, causing the heart to beat out of rhythm - too quickly, too slowly or with an irregular pattern.
Arrhythmias are fairly common. Most people have had at least one experience where it feels as if the heart has skipped a beat, or has given an unexpected flutter. For many, the experience is usually not cause for concern. However, while many arrhythmias are harmless, some can be extremely dangerous and require medical treatment.
