Medication
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.

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.
Management and Treatment
You may not need treatment. Some people may feel better after resting more, drinking less coffee or alcohol or after quitting smoking.
Prevention
If your SVT (supraventricular tachycardia) is from causes you can control, you can:
Living With
Lifestyle changes can help with SVT (supraventricular tachycardia). You can:
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.
What is the P wave in EKG?
On surface ECG, the P waves are usually seen before every QRS complex and have a different axis than a sinus P wave. At high atrial rates, the P waves may be embedded in the descending limb of the T wave or completely obscured by the T waves.7. Open in a separate window.
Where does atrial flutter originate?
Atrial flutter originates from an anatomic macro–re-entrant circuit in the atria. The most common (typical) atrial flutter involves counterclockwise conduction in the right atrium along an anatomic circuit including the cavotricuspid isthmus (the area between the inferior vena cava and the tricuspid annulus).
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.
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.
Is the P wave axis positive in lead II?
The ectopic P wave (arrows) axis is positive in lead II. Although sinus tachycardia may give a similar P wave axis, the atrial rate of about 215 beats/min suggests atrial tachycardia. Electrophysiologic mapping confirmed an ectopic atrial focus in the right atrium.
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.
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.
