Arrhythmia: Tachycardia is a general term applied to any fast heart rate including tachyarrhythmias. A tachyarrhythmia specifically implies a form of arrhythmia which causes a fast heart rate, not all arrhythmias cause a fast heart rate. Tachycardia is defined as a heart rate more than 100, normal heart rhythm is frequently more than 100 in exercise, excitement, fevers, etc. None of these are arrhythmias.
