Irregularities in heart rhythm in which the heart can beat either too fast (tachycardia) or too slow (bradycardia). Arrhythmias may reduce the heart's ability to pump efficiently.

Arrhythmia is an abnormal rate of muscle contractions in the heart; An arrhythmia is any disorder of heart rate or rhythm; An arrhythmia is any deviation from or disturbance of the normal heart rhythm (from American Heritage Dictionary and WebMD).

Variations in the normal rhythm of the heartbeat.

Abnormal rhythms of the heart beat. Premature contractions: can be atrial or ventricular. May or may not be dangerous. Interrupts the regular heart rhythm. Fibrillation: can be atrial or ventricular. Ineffective beats. Tachycardia: fast heart beat, usually over 110 a minute. Bradycardia: slow heart beat, usually under 50 beats a minute
