Catheter ablation: This outpatient procedure is used to treat or cure many types of heart arrhythmia, including PSVT. Catheter ablation is a mature technique known to be safe and effective. Therefore, it is considered a first-line therapy for PSVT.
What is first-line treatment for PSVT?
The first-line treatment in hemodynamically stable patients, vagal maneuvers, such as breath-holding and the Valsalva maneuver (ie, having the patient bear down as though having a bowel movement), slow conduction in the AV node and can potentially interrupt the reentrant circuit.
Does PSVT need to be treated?
Over time, PSVT can weaken your heart muscle. In severe cases, PSVT can lead to loss of consciousness, and it can even cause sudden cardiac arrest. If you have PSVT, see your provider regularly so they can monitor your heart health. In almost all circumstances, PSVT can be cured with catheter ablation.

Is PSVT normal?
PSVT is a fairly common type of abnormal heart rate. It can occur at any age and in people who don't have other heart conditions. The heart's sinus node typically sends electrical signals to tell the heart muscle when to contract. In PSVT, an abnormal electrical pathway causes the heart to beat faster than normal.
How long does a PSVT episode last?
Episodes can last for seconds, minutes, hours or (in rare cases) days. They may occur regularly, several times a day, or very infrequently, once or twice a year. The heart rate may be as high as 250 beats per minute, but is usually between 140 and 180 (a normal heartbeat should be 60-100 beats per minute at rest).

Is catheter ablation safe?
Catheter ablation is typically safe. But it could damage blood vessels or lead to infection.
Overview
Paroxysmal supraventricular tachycardia (PSVT) is a general term used to describe a type of arrhythmia (irregular heartbeat). Tachycardias are faster-than-normal heartbeats. If you have this condition, your heart may suddenly beat more quickly. Just as suddenly, your heart may slow down and beat at a normal rate.
Symptoms and Causes
PSVT (also called re-entry tachycardia) is a type of atrial arrhythmia. It happens when there is abnormal electrical activity in the atria. This is caused by an abnormally irritable area in the atria or by a short circuit in your heart causing electrical signals to travel around and around in a circular pattern.
Management and Treatment
Depending on your overall health and symptoms, you may not need treatment. If you have an arrhythmia, you’ll see a special type of heart doctor called a cardiologist. They may recommend you:
Prevention
You may not be able to avoid PSVT. But you can lower your risk by making smart lifestyle choices and staying healthy. To lower your risk, you should:
Living With
If you have any concerns about your heartbeat or you have symptoms of arrhythmia, talk to your provider. If you have PSVT, it’s very important to see your cardiologist regularly.

Do children with SVT need to be treated?
Children who have brief or infrequent bouts of SVT may not need treatment but should receive regular supervision (Mayo Clinic, 2019).
Is SVT a life threatening condition?
The outlook for children with SVT is excellent. The problem is usually not life- threatening plus the current treatments are highly effective. Successful ablation procedures lead to a cure. With no increased incidence of long term effents. https://www.mayoclinic.org/medical-professionals/cardiovascular-diseases/news/managing-pediatric-supraventricular-tachycardia/mac-20474690
What is the treatment for paroxysmal supraventricular tachycardia?
Acute management of paroxysmal supraventricular tachycardia (PSVT) includes controlling the rate and preventing hemodynamic collapse. If the patient is hypotensive or unstable, immediate cardioversion with sedation must be performed. If the patient is stable, vagal maneuvers can be used to slow the heart rate and to convert to sinus rhythm. If vagal maneuvers are not successful, adenosine can be used in increasing doses. If adenosine does not work, atrioventricular (AV) nodal blocking agents like calcium channel blockers or beta-blockers should be used, as most patients who present with PSVT have AV nodal reentrant tachycardia (AVNRT) or AV reentrant tachycardia (AVRT). These arrhythmias depend on AV nodal conduction and therefore can be terminated by transiently blocking this conduction.
Who should be consulted for patients with paroxysmal SVT, syncope, and/or preex?
A cardiologist should be consulted for patients with frequent episodes of paroxysmal SVT, syncope, and/or preexcitation syndromes. Consultation with a cardiologist should also be obtained for patients in whom medical management has failed.
What is the normal heart rate for atrioventricular nodal reentrant tachycardi?
Atrioventricular nodal reentrant tachycardia. The patient's heart rate is approximately 146 bpm with a normal axis. Note the pseudo S waves in leads II, III, and aVF. Also note the pseudo R' waves in V1 and aVR. These deflections represent retrograde atrial activation.
What is the best treatment for preexcited atrial fibrillation?
Patients with preexcited atrial fibrillation should not be treated with intravenous AV nodal blocking agents, such as adenosine, beta-blockers, calcium channel blockers, and digoxin. Rather, if the patient is hemodynamically stable, intravenous procainamide should be administered. If the patient is unstable, direct current cardioversion should be performed.
How to treat atrial fibrillation?
The treatment of atrial fibrillation and atrial flutter involves controlling the ventricular rate, restoring the sinus rhythm, and preventing embolic complications. The ventricular rate is controlled with calcium channel blockers, digoxin, amiodarone, and beta-blockers. The sinus rhythm may be restored with either pharmacologic agents or electrical cardioversion. Medications such as ibutilide, propafenone, and flecainide convert atrial fibrillation and atrial flutter of short duration to sinus rhythm. Since atrial fibrillation and atrial flutter increase risk of stroke or cerebrovascular accidents, anticoagulation is usually recommended. Drugs like warfarin, as well as novel oral anticoagulant agents like dabigatran, rivaroxaban, and apixaban, may be used for anticoagulation. [ 58, 59, 60]
What is the most effective method for restoring sinus rhythm?
Electrical cardioversion is the most effective method for restoring sinus rhythm. Synchronized cardioversion starting at 50J can be used immediately in patients who are hypotensive, have pulmonary edema, have chest pain with ischemia, or are otherwise unstable.

For some people, supraventricular tachycardia is triggered or worsened by stress or exercise.
How to diagnose supraventricular tachycardia?
To diagnose supraventricular tachycardia, your doctor will ask questions about your symptoms and your medical history and perform a physical exam. Blood tests are usually done to check for other health conditions that could cause your symptoms, such as thyroid disease.
How does cardioversion work?
Cardioversion may be done using medications or during a heart procedure. In the procedure, a shock is delivered to your heart through paddles or patches on your chest. The current affects the electrical signals in your heart and can restore a normal rhythm. Medications.
Overview
When your heart rhythm isn’t normal or the speed of the heartbeats isn’t right, you might have an arrhythmia. There are different names for different kinds of arrhythmias, depending on where they happen in the heart and what causes the problem. Tachycardia means your heart is beating too fast.
Symptoms and Causes
A problem with your heart’s electrical signals or circuitry causes SVT, but some people may not be aware of what brings on their symptoms. Others have a clear “trigger” like stress or exercise that starts their SVT. Things that can bring about symptoms include:
Diagnosis and Tests
Your healthcare provider will most likely do an electrocardiogram (EKG or ECG). If your provider needs to study your heart for a longer amount of time, they may ask you to wear a heart monitor that records the electrical activity in your heart.
