Arrhythmia

An arrhythmia (also called dysrhythmia) is an abnormal rhythm of the heart, which can cause the heart to pump less effectively. It:

• many occur in people who don’t have underlying heart disease
• occurs more frequently in adults
• can be classified as slow (bradyarrhythmia) or fast (tachyarrhythmia)
