How do you treat AVNRT?

Medications used to terminate symptomatic AVNRT episodes and to reduce AVNRT occurrences include beta-blockers, calcium channel blockers, and less commonly digoxin. These medications can be administered orally on a routine outpatient basis, or via intravenous route if necessary in the emergency room.

Is AVNRT life threatening?

AVNRT is not considered, in and of itself, a dangerous condition. However, in conjunction with certain other heart conditions, it can lead to more severe consequences and even a heart attack (sometimes called demand ischemia).

Can AVNRT be cured?

AVNRT can be completely cured with ablation therapy in over 95% of cases.

What is AV reentry tachycardia?

Atrioventricular nodal reentry tachycardia (AVNRT) is the most common type of supraventricular tachycardia. People with AVNRT have episodes of an abnormally fast heartbeat (more than 100 beats per minute) that often start and end suddenly.

What is the definition of AV node?

The atrioventricular node, or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart.

Is AVNRT dangerous?

Usually AVNRT can be cured at the first attempt in 90-95% of people. If it returns, more attempts can be made. As with any other invasive procedure there are risks although these are small. Fortunately complications only occur in about 1% of patients. The most important risk is that of damaging the AV node itself.

What is the best drug treatment for SVT?

Typical medicines used to treat svt include beta blockers or calcium blockers. Some svts require more potent medications or an invasive procedure called ablation. The key is to capture and define the specific rhythm problem – that will dictate the treatment. Good luck.

What are the types of tachycardia?

Atrioventricular nodal reentrant tachycardia (AVNRT) is a common type of supraventricular tachycardia. It accounts for many of the fast heart rates that start in the upper part of the heart (excluding atrial fibrillation). Atrioventricular (AV) nodal reentrant tachycardia can cause symptoms at any age.
