Sinus and Supraventricular Tachycardia

Supraventricular tachycardia (SVT) is a heart rate greater than 100 beats/minute that originates above the ventricle. It includes sinus tachycardia, paroxysmal SVT (PSVT) and atrial tachycardias. Sinus and other supraventricular tachycardias are often well-tolerated and the only finding is a fast heart rate. In most cases, the only management is initial cardiac monitoring, establishment of intravenous access, supplemental oxygen and simple observation. Drugs that can control are adenosine, verapamil and digoxin.
