Medication
Calcium channel or beta blockers can help correct heart rhythm. If you have SVT only 1 or 2 times a year, you may take beta-blockers or calcium channel medicines by mouth (orally) as needed. If your SVT is more frequent, you may need to take medicine every day.
Procedures
Intravenous administration of diltiazem or verapamil can be effective for acute treatment in patients with hemodynamically stable SVT (class IIa recommendation, level B-R evidence) Intravenous use of β-blockers is reasonable for acute treatment in patients with hemodynamically stable SVT (class IIa recommendation, level C-LD evidence)
Therapy
Medications to Treat SVT. Medications to Treat Supraventricular Tachycardia (SVT) To best treat supraventriculat tachycardia, medications need to affect the conductivity of the A-V node, the staircase between the upper and lower heart chambers. These medications include: Beta-blocking agents. Calcium channel agents.
Nutrition
Patients may experience an episode of SVT once every several months, or a few times a year. Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment.

What is the first line treatment for stable SVT?
Vagal maneuvers are an appropriate first treatment option in patients with hemodynamically stable SVT. Studies report an approximately 25% success rate, although reported rates vary widely in the literature (6%-54%). The most commonly performed maneuvers are the Valsalva maneuver and carotid sinus massage.
How do you treat stable SVT?
Valsalva maneuvers are effective in terminating SVT in hemodynamically stable patients. Intravenous adenosine, verapamil, and diltiazem are effective in acute termination of SVT. Beta blockers (metoprolol, atenolol, propranolol, and esmolol) are effective in acute termination of SVT.
Do you give adenosine for SVT?
Adenosine is administered intravenously in specific clinical cases. For the management of SVT, adenosine is ideally given through a peripheral intravenous (IV) access initially as a 6 mg dose followed by a 20 mL saline flush for rapid infusion.
How to treat SVT?
The Valsalva maneuver Tightly close your mouth, pinch your nose shut, and try to breathe out as hard as you can for 10 to 15 seconds. The Valsalva maneuver is always the first-line treatment for an attack of SVT. Cold water Apply ice water to the face for about five seconds.
How to treat rapid heartbeat?
An attack of rapid heartbeats is typically treated with physical maneuvers or a self-administered, as needed “pill-in-the-pocket” approach to restore a slower heartbeat. For emergency and unstable situations, an adenosine injection or electrical cardioversion will rapidly restore a normal heartbeat.
What are the symptoms of supraventricular tachycardia?
The most common symptoms of supraventricular tachycardia include: Rapid heart rate. Palpitations. Chest discomfort.
What is the vagal maneuver?
Vagal maneuvers. The vagus nerve slows down the two central nerve nodes in the heart. When the vagus nerve is stimulated, then , the heart rate decreases. It goes to work whenever blood pressure rises in the aorta, the main artery leaving the heart.
Is SVT a health problem?
Most people with SVT have structurally normal hearts, and the condition is usually not a health threat. A person with atrial fibrillation often has structural problems with their heart and patients are at increased risk for blood clots, stroke, heart failure, or heart attack.
Does adenosine help with SVT?
When taken as an injection, adenosine slows down the AV node, the primary cause of SVT symptoms. If intravenous adenosine does not work, the next step will be intravenous calcium-channel blockers ( diltiazem or verapamil ), beta-blockers ( esmolol or metoprolol ), or antiarrhythmic medications (procainamide or amiodarone ). All of these drugs slow down the AV node.
Is SVT a tachycardia?
SVT should not be confused with atrial fibrillation or atrial flutter. Technically, both are types of supraventricular tachycardias. SVT is characterized by a fast but regular heartbeat.
What is the treatment for recurring SVT?
Ongoing treatment of recurring SVT. If you have recurring episodes of SVT, you may need to take medicines, either on an as-needed basis or daily. Medicine treatment may include beta-blockers, calcium channel blockers, or other antiarrhythmic medicines.
How to treat sudden onset SVT?
Your doctor will teach you how to do these safely. These are things such as bearing down or putting an ice-cold wet towel on your face.
How to tell if you have SVT?
SVT is usually treated if: 1 You have symptoms such as dizziness, chest pain, or fainting that are caused by your fast heart rate. 2 Your episodes of fast heart rate are occurring more often or do not return to normal on their own.
How is supraventricular tachycardia treated?
How is supraventricular tachycardia (SVT) treated? Your treatment for SVT depends on a few things. They include what type of SVT, how often you have episodes, and how severe your symptoms are. The goals of treatment are to prevent episodes, relieve symptoms, and prevent problems.
What are the symptoms of SVT?
SVT is usually treated if: You have symptoms such as dizziness, chest pain, or fainting that are caused by your fast heart rate. Your episodes of fast heart rate are occurring more often or do not return to normal on their own.
What to do if you have a SVT?
Medications. If you have frequent episodes of SVT, your doctor may prescribe medication to control your heart rate or restore a normal heart rhythm. It's very important to take the medication exactly as directed by your doctor in order to reduce complications. Catheter ablation.
What is the test for SVT?
Tests to diagnosis SVT include: Electrocardiogram (ECG). During an ECG, sensors (electrodes) that can detect the electrical activity of your heart are attached to your chest and sometimes to your limbs. An ECG measures the timing and duration of each electrical phase in your heartbeat. Holter monitor.
What is a supraventricular tachycardia test?
This device detects abnormal heart rhythms and is implanted under the skin in the chest area. If your doctor doesn't find a heart rhythm problem during those tests, you may need other tests, such as: Stress test. 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.
How to stop SVT?
You may be able to stop an episode of SVT by using particular movements such as holding your breath and straining as you would during a bowel movement, dunking your face in ice water, or coughing.
How to prevent heart disease?
Being overweight increases your risk of developing heart disease. Keep blood pressure and cholesterol levels under control. Make lifestyle changes and take medications as prescribed to correct high blood pressure (hypertension) or high cholesterol. Limit alcohol.
What medicine can be given to prevent SVT?
For emergent cases, calcium channel or beta blockers can be given through IV (intravenously) for more rapid correction of the heart rhythm. Adenosine is another medicince that can be given through IV as well that can work in a matter of seconds.
How to prevent SVT?
Your healthcare provider might suggest other ways to help prevent SVT, such as the following: 1 Have less alcohol and caffeine 2 Don't smoke 3 Lower your stress 4 Eat foods that are healthy for your heart 5 Don't take recreational drugs, especially stimulants that can over-excite the heart muscle. Some herbs and supplements can have this same effect. Always check with your healthcare team before you take any non-prescribed medicines. 6 Stay well hydrated and get enough sleep
How does a SVT catheter work?
Your healthcare provider puts a thin, flexible tube (catheter) into a blood vessel in the groin. He or she then gently pushes it up into your heart. The area of your heart that causes your SVT is then either cauterized with heat or scarred with freezing energy.
How to correct heart rhythm right away?
Valsalva maneuver. This is a way to increase pressure in the abdomen and chest. It can correct your heart rhythm right away. To do it, you bear down with your stomach muscles, as though you are trying to have a bowel movement. Carotid massage. Your healthcare provider may rub the carotid artery in your neck.
Introduction: What Is Supraventricular Tachycardia?
Supraventricular tachycardia (SVT) is an arrhythmia initiated above the ventricles, at or above the atrioventricular (AV) node. This cardiac rhythm occurs due to improper electrical conduction within the heart that disrupts the coordination of heartbeats.
What Are ECG Characteristics of Supraventricular Tachycardia?
Typically characterized by having a narrow QRS complex that is less than or equal to 0.12 seconds. A wide QRS (greater than or equal to 0.12 seconds) can occur, but is less common.
What Signs or Symptoms May Be Present?
Symptom severity tends to be associated with the duration of time that supraventricular tachycardia takes place. Signs or symptoms that may present with SVT include:
Treatment of Supraventricular Tachycardia
Care of the conscious patient should be initiated using the Advanced Cardiovascular Life Support (ACLS) Primary Assessment. Components of this assessment include evaluating the patient’s airway, breathing, circulation, disability, and potential exposure.
How To Prepare for Your ACLS Exam
Are you ready to test your knowledge and skills to identify and treat supraventricular tachycardia? Numerous quizzes are available to help you evaluate and reinforce your understanding of cardiac rhythms. You may access quizzes here and here.
What is a supraventricular tachycardia?
Supraventricular tachycardias are usually narrow-complex tachycardias with a QRS interval of 100 ms or less on an electrocardiogram (ECG). Occasionally, they may show a wide QRS complex in the case of a pre-existing conduction delay, an aberrancy due to rate-related conduction delay or a bundle branch block.
Should a patient with SVT be referred to a cardiologist?
All patients with symptomatic SVT should be referred to a cardiologist for assessment and management. Depending on patient preferences, curative radiofrequency ablation should be considered because of its high success rate, which will subsequently improve quality of life and reduce associated costs. Key points.
Does adenosine slow the ventricular rate?
In patients whose tachycardia does not involve the AV node (e. g., atrial flutter and atrial tachycardia), vagal manoeuvres or intravenous use of adenosine may slow the ventricular rate briefly and thu s unmask the underlying atrial rhythm.
Is AVNRT a sinus rhythm?
A narrow-complex tachycardia with a regular rhythm is likely to be sinus tachycardia, AVRT, AVNRT, atrial flutter or atrial tachycardia.
What is the primary factor to consider when considering hemodynamic stability?
Outside of a hospital, the primary factor to consider is hemodynamic stability —that is, the stability of blood flow from the heart to the brain. When there is hemodynamically unstable tachycardia, the chambers of the heart do not have enough time to fill with blood between contractions. A patient with no obvious signs of hemodynamic instability ( ...
What is tachycardia in 2021?
Updated on May 16, 2021. Tachycardia (rapid heart rate ) is one of the more complicated dysrhythmias to treat because it has so many presentations and so many causes. This article focuses on the treatment of cardiac-related unstable tachycardia in the emergency setting by prehospital professionals.
Can a patient with no obvious signs of hemodynamic instability be transported to the hospital?
A patient with no obvious signs of hemodynamic instability ( low blood pressure, thready or weak pulse, postural changes, etc.) can probably be safely transported to the hospital without attempting to treat the tachycardia first.
Does adenosine help with tachycardia?
Adenosine works very similarly to electrical cardioversion, leading to depolarization of the heart muscle and allowing the sinus node to reset. If adenosine doesn't work, which is very likely if the tachycardia is irregular, two other classes of medication can be tried.
