Medication
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.
Procedures
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.
Therapy
Usually, these medications are taken daily, and take approximately 10-20 minutes to act. Medication for longer episodes of SVT For patients who have longer episodes of supraventricular tachycardia, a quick-acting version of one of these three medications may be given.
Nutrition
What is SVT? Supraventricular tachycardia occurs when the heart occasionally beats too fast for no identifiable reason. A glitch in nerve signals rather than a problem with heart muscles causes the heart to beat too fast (tachycardia).

Medications typically used to treat SVT are: Beta Blockers: A beta blocker is a very safe medication that works by reducing the effect adrenalin has on the heart. Beta blockers are commonly used to treat high blood pressure and other common heart problems. Calcium Channel Blockers.
What drug is recommended for acute treatment in patients with regular supraventricular tachycardia?
Intravenous diltiazem, verapamil, or metoprolol is recommended for control of heat rate in patients with hemodynamically stable atrial flutter (moderate-quality evidence) and for the treatment of hemodynamically stable focal atrial tachycardia (low-quality evidence).
Does metoprolol stop SVT?
Other IV beta-blockers, such as metoprolol or labetalol, also can be used to treat SVT acutely. Commonly, metoprolol is given, and most medical personnel are very familiar with its use. It can be used in an intermittent dosing strategy if it does not convert the SVT after initial administration.
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.

What are the symptoms of supraventricular tachycardia?
The most common symptoms of supraventricular tachycardia include: Rapid heart rate. Palpitations. Chest discomfort.
What is the heartbeat?
A heartbeat begins when the atria contract and push blood into the bottom two chambers—the ventricles. After the ventricles fill with blood, they contract and push blood out to the lungs (right ventricle) or the rest of the body (left ventricle).
What is the cause of sudden heart palpitations?
Supraventricular tachycardia, or SVT, causes unexpected and often short-lived heart palpitations. The good news is they are rarely a health threat and most of the time they stop on their own after a few seconds or minutes.
What is the heart's pacemaker?
Sometimes referred to as the heart’s “pacemaker,” this nerve bundle first sends out electrical impulses that cause the two upper chambers to contract. The nerve signal terminates at another node, the atrioventricular node (AV node), a kind of crossing gate to the lower chambers.
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.
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.
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 tell if you have SVT?

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

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 triggers SVT?
While the “extra nerve” causes SVT, an attack of SVT may require certain triggers, which include caffeine, alcohol, some herbal medications, and some over-the-counter cold medications containing stimulants.
What is supraventricular tachycardia?
What is a supraventricular tachycardia? Simply stated, an SVT is an arrhythmia that originates from above (“supra”) the ventricle. This term encompasses a large number of arrhythmias and therefore the term “SVT” is only a general description, not a specific diagnosis.
What is the extra nerve in the heart?
An “extra nerve” exists in the heart of nearly all patients with SVT, which over time becomes active and causes fast heartbeat. Most cases of SVT are genetic. In other words, patients are born with this “extra nerve” in the heart but it may remain dormant for many years, often surfacing when patients reach their 20s and 30s. Rarely, some patients may be diagnosed for the first time in their 60s and 70s.
Does ice tea cause SVT?
Just because a large ice tea triggered an SVT attack, it does not mean that it caused the SVT. For, without the ice tea, the “extra nerve” is still present, just waiting for another trigger to cause another attack later.
Can SVT be treated with medication?
Most SVTs can be treated with medications but medications represent a temporizing measure, not a cure for the condition. For children or young adults, life-long therapy with medication (s) may not be reasonable. Ablation is the only curative treatment options for SVT.
