Supraventricular tachycardia (SVT) presents as a rapid heart rhythm originating at or above the atrioventricular node. It can be contrasted with the potentially more dangerous ventricular tachycardias—rapid rhythms that originate within the ventricular tissue. Although `SVT` can be due to any supraventricular cause, the term usually refers to .....

, SVT, means the heart is beating too fast and irregularly. Instead of the normal heart rate of about 60 to 80 beats per minute, it is from 140 to 200. It may be caused by too much stress, coffee, smoking, or alcohol; or by viral infections. It may occur spontaneously, or may occur by the rate not returning to normal when resting after exercise.

Supraventricular tachycardia: Abbreviated SVT. A regular, abnormally fast heart beat (tachycardia) caused by rapid firing of electrical impulses from a focus above the atrioventricular node (A-V node) in the heart. Called supraventricular because the tachycardia originates above the ventricles of the heart. Common Misspellings: supraventricular tac...

(SVT) A regular rapid heart rate (150-250 beats per minute) that is caused by events triggered in areas above the hearts lower chambers (the ventricles); see also paroxysmal supraventricular tachycardia (PSVT).
