An arrhythmia, also called dysrhythmia, is an irregular or abnormal heartbeat. When arrhythmias are severe or long-lasting, the heart may not be able to pump enough blood to the body. Arrhythmias can occur in nearly anyone, becoming more common as we age. But some factors may place people at greater risk.
What Are the Symptoms of an Arrhythmia?
An arrhythmia may be silent and not cause any symptoms. A doctor can detect an irregular heartbeat during an examination by taking your pulse, listening to your heart, or by performing diagnostic tests.
If symptoms occur, they may include:
Palpitations (a feeling of skipped heartbeats or fluttering)
Holter Monitor: A small portable recorder that is attached to electrodes on your chest. It continuously records your heart’s rhythm for 24 hours.
Transtelephonic Monitor: A small, portable recorder that is worn continuously for an extended period of time to record and save information about your heart’s rhythm around the time you experience an arrhythmia. The recording is triggered by pushing a button (event button). The rhythm is recorded, saved, and transmitted over the phone line.
