Tachycardia (C0039231)

Definition (NCI) Rapid beating of the heart, usually defined as greater than 100 beats per minute.
Definition (NCI) Tachycardia; an abnormally rapid heartbeat, usually applied to a heart rate above 100 per minute.
Definition (CSP) excessive rapidity in the action of the heart.
Definition (MSH) Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.
