An arrhythmia can also mean that your heart beats irregularly (skips a beat or has an extra beat). A small number of people, however, have arrhythmias that are dangerous and require treatment. Arrhythmias are also more serious if you have other heart problems. Your doctor will talk with you about the type of arrhythmia you have and whether you need treatment.
Causes & Development The heart has 4 chambers. The walls of the heart contract to push blood through the chambers. The rate of the contractions is influenced by nerve impulses and hormones in the blood. A problem here, or signals coming from elsewhere, can cause an arrhythmia.
Minor arrhythmias may be caused by excessive alcohol use, smoking, caffeine, stress or exercise. These occasional changes can be brought on by strong emotions or exercise. They usually are not a cause for alarm. Arrhythmias that occur more often or cause symptoms may be more serious and need to be discussed with your doctor.
Treatment & Prevention Treatment depends on the type of arrhythmia you have. Some mild arrhythmias require no treatment. |
