some people with atrial or supraventricular tachycardia (SVT). This is known as the oculocardiac reflex. Medications Adenosine, an ultra-short-acting AV nodal blocking agent, is indicated if vagal maneuvers are not effective. If unsuccessful or the PSVT recurs diltiazem or verapamil are recommended. Adenosine may be safely used during pregnancy. SVT that does not involve the AV node may respond to other anti-arrhythmic drugs such as sotalol or amiodarone. Cardioversion If the person is hemodynamically unstable or other treatments have not been effective, synchronized electrical cardioversion may be used. In children this is often done with a dose of 0.5 to 1 J/Kg.
