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. In people who have frequent episodes, treatment with medicines can decrease how often these occur.
What are the different types of SVT medications?
There are two major types of SVT medications. Rate control medications return the heart to a normal pace. Rhythm control medications (arrhythmic drugs) restore an organized heartbeat. Either will be used depending on the type and severity of the patient’s condition.

Many people with SVT do not need drugs. When drugs are necessary, doctors will use heart rate medications to slow down the heart or heart rhythm medications to both slow down the heart and block stray electrical signals that are causing the heart to beat fast. What happens if SVT goes untreated?
How is SVT treated in patients with hemodynamically stable SVT?
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)

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.

A narrow-complex tachycardia with a regular rhythm is likely to be sinus tachycardia, AVRT, AVNRT, atrial flutter or atrial tachycardia.
Is there a lack of accepted safety for use under medical supervision?
Has a high potential for abuse. Has a currently accepted medical use in treatment in the United States or a currently accepted medical use with severe restrictions. Abuse may lead to severe psychological or physical dependence.
Is fetal risk based on adverse reaction data?
Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use in pregnant women clearly outweigh potential benefits. N. FDA has not classified the drug.
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.
