An arrhythmia (also called dysrhythmia) refers to what is usually an irregular heartbeat. The heart rate can be fast, slow, or irregular, taking into consideration age and activity. For example, a newborn's heart beats much faster than a 5-year-old child's heart. A fast heart rate is called tachycardia. A slow heart rate is called bradycardia. Some irregular heartbeats are normal: Sinus arrhythmia is the normal variation in heart rate that accompanies breathing in and out.
