Dysrhythmia (Arrhythmia) or Abnormal Heart Pattern
Definition
A dysrhythmia is an abnormal beating of the heart.
Causes
Dysrhythmias are often due to electrical conduction problems within the heart.
Treatment
The heart must be tested with electrocardiography (ECG) to determine the type of abnormality. Some dysrhythmias do not require treatment. Others can be treated with medication. In more serious cases, a pacemaker may be needed.
Comments
In the most severe situations, such as ventricular fibrillation or ventricular tachycardia, a person can die if the abnormal heart pattern is left untreated.
