An arrhythmia is an abnormal heart rhythm, a change in either the pace or pattern of the heartbeat. The heart may be beating too slowly, too rapidly or irregularly. An abnormal heart rhythm may cause a skipping or fluttering sensation in the chest. More serious rhythm disturbances may cause lightheadedness, fainting or shortness of breath. My heart seems to skip a beat once in a while.
Arrhythmias are common.
In fact, most people experience extra beats now and then. Although arrhythmias are more common in people with heart disease, they can also occur in people who have perfectly normal hearts. Most people with arrhythmias have nothing to fear and do not need extensive testing or treatment. Arrhythmias occurring along with other heart problems, such as coronary artery disease, are potentially serious and may require evaluation. Once the diagnosis is made, treatment options can be considered.
