What is first-line treatment for PSVT?
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 the drug of choice for PSVT?
Verapamil is considered by many investigators to be the drug of choice for the acute management of uncomplicated PSVT. Several clinical investigators have demonstrated termination of PSVT in more than 90% of their patients within minutes following IV drug administration.
Which drugs is the most preferred for the treatment of PSVT?
At this time, adenosine is the drug of choice of treatment. Verapamil and diltiazem are the most commonly used calcium channel blockers (CCBs). This review aimed to compare the efficacy of both drugs in the treatment of PSVT.
What is the first-line drug administered for a stable SVT?
Adenosine is the primary drug used in the treatment of stable narrow-complex SVT (Supraventricular Tachycardia). Now, adenosine can also be used for regular monomorphic wide-complex tachycardia.
Why verapamil is used in PSVT?
Our study showed that oral verapamil can decrease the early recurrence of PSVT (after its successful control with intravenous adenosine) effectively while showing no significant adverse reactions.
Is metoprolol used to treat SVT?
Beta blockers (metoprolol, atenolol, propranolol, and esmolol) are effective in acute termination of SVT. Adenosine may be used for diagnosis and treatment of undifferentiated regular wide complex tachycardia.
Is digoxin used to treat SVT?
Medications to Treat Supraventricular Tachycardia (SVT) These medications include: Beta-blocking agents. Calcium channel agents. Digoxin.
When is adenosine given?
Adenosine has uses as both a diagnostic or therapeutic agent. As a diagnostic agent, adenosine can be utilized in myocardial perfusion stress imaging due to its vasodilatory effects. As a therapeutic agent, adenosine can be used due to its antiarrhythmic properties in supraventricular tachycardia (SVT).
What is amiodarone used for?
Amiodarone is used to treat life-threatening heart rhythm problems called ventricular arrhythmias. This medicine is used in patients who have already been treated with other medicines that did not work well.

Is Cardizem used to treat SVT?
Pharmacological Use Diltiazem has a COR I, LOE-b classification, used for rate control of atrial arrhythmias, predominantly Atrial Fibrillation, and COR IIa, LOE-b for treatment of SVT with a reentry pathway mechanism.
When do you take adenosine or amiodarone?
Note that amiodarone becomes the antiarrhythmic of choice (after failure of adenosine) if the patient's cardiac function is impaired and the ejection fraction is <40% or there are signs of congestive heart failure.
What is the most common cause of PSVT?
Atrioventricular nodal re-entrant tachycardia (AVNRT) is the most common cause of PSVT. It occurs when a small extra pathway exists in or near the AV node — the "gate" that sends electricity from the upper chambers (atria) to the lower chambers (ventricles).
Why does PSVT cause shortness of breath?
PSVT occurs because of a short circuit — an abnormal electrical pathway made of heart cells — that allows electricity to speed around in a circle and repeat the signal over and over. As a result, the chambers contract rapidly, which may impair heart function and cause symptoms such as lightheadedness or shortness of breath.
What is EP study?
This test not only diagnoses the condition but also identifies the precise cause. A diagnostic EP study is always done before catheter ablation, usually as part of the same procedure. With the patient under light sedation, several narrow, flexible wires are threaded through a vein to your heart.
Why do people with Wolfe-Parkinson-White syndrome need to have catheter ablation?
Due to an increased risk of sudden cardiac death, people with Wolfe-Parkinson White syndrome are advised to have curative catheter ablation. Wolff-Parkinson-White syndrome is congenital, developing in utero.
Is catheter ablation a first line therapy for PSVT?
Therefore, it is considered a first-line therapy for PSVT. It is often reasonable to go straight to catheter ablation rather than trying a medication first. Learn more about arrhythmias or visit the Johns Hopkins Electrophysiology and Arrhythmia Service.
Is AvnRT a life threatening arrhythmia?
An electrical impulse that enters this pathway will circle rapidly, causing a sudden (paroxysmal), fast heartbeat in both the atria and the ventricles. AVNRT is not a life-threatening arrhythmia, but it can cause symptoms such as lightheadedness or syncope (fainting).
Can you treat PSVT on its own?
Because PSVT does not resolve on its own, medications would be taken for a lifetime. 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.
What is PSVT in medicine?
Paroxysmal supraventricular tachycardia (PSVT) is episodes of rapid heart rate that start in a part of the heart above the ventricles. "Paroxysmal" means from time to time.
What is a lack of accepted safety for use under medical supervision?
There is a lack of accepted safety for use under medical supervision. 2. 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. 3.
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.
Why is PSVT called paroxysmal?
It is referred to as paroxysmal because the rapid rate can occur sporadically and without warning and may also stop on its own.
Why does a cold cause a PSVT?
PSVT can result because of underlying medical conditions or because of foods and medications that are ingested. Caffeine, alcohol, and over-the-counter (OTC) cold medications that contain pseudoephedrine can stimulate and irritate the heart's electrical conduction system and precipitate an episode of PSVT.
What is the best treatment for atrial tachycardia?
Other treatment options for other atrial tachycardias include calcium channel blockers, beta blockers, digoxin, and amiodarone. If the PSVT does not convert with intravenous medication or if the patient has low blood pressure or complains of chest pain or shortness of breath, cardioversion may be required.
Can you pass out with PSVT?
By its nature, PSVT is intermittent and its onset cannot be predicted.
What is SVT in cardiac?
SVT generally refers to any tachyarrhythmia generated above the His/Purkinje system. For simplicity, the term pSVT in this post will refer to only Atrioventricular Nodal Tachycardia (AVNRT), as it is the most common tachyarrhythmia in patients with normal cardiac structure [1].
Is a calcium channel blocker a second line drug?
There has to be something else.”. You know Calcium Channel Blockers (CCBs) are recommended as a second line drug if adenosine does not terminate the SVT, or if adenosine is contraindicated .
Is verapamil good for SVT?
Adenosine and Verapamil are equally effective for SVT. Moderate evidence by recent Cochrane review. Class IIa by ACC/AHA. Adenosine has a much higher incidence of minor side effects. chest pain, facial flushing, nausea, headache, and lightheadedness/dizziness. Verapamil has a slightly higher risk of hypotension.
What are the risk factors for SVT?
Although SVT episodes can occur in anyone, there are certain factors that may increase an individual’s risk. Examples of these risk factors include 2,7-13: • Excessive caffeine or alcohol use. • History of tobacco use.
What is the treatment for short term management?
Short-term management treatment options can involve both pharmacologic and nonpharmacologic measures. In most patients, the drug of choice for acute therapy is either adenosine or verapamil. 7,18,19 The use of intravenous adenosine or the calcium channel blocker verapamil are considered safe and effective therapies for controlling SVTs. 4,7,18,19
What should a pharmacist counsel patients on?
Pharmacists should counsel patients on the proper use of any prescribed medications, including the proper use, potential adverse effects, contraindications associated with the selected therapy, and the importance of adherence.
What diagnostic tools do doctors use?
Physicians may also elect to use other diagnostic tools, such as an event monitor or a Holter monitor, blood work (ie, thyroid stimulating hormone levels, metabolic profile, complete blood count, cardiac enzymes), electrophysiology study, or an echocardiogram. 2,4-8,18.
Can SVT be misdiagnosed?
Because SVT can be episodic, it can sometimes be misdiagnosed as anxiety or a panic disorder. For this reason, obtaining a thorough patient medical and medication history is very important in the diagnosis of SVTs and to help determine possible triggers. 4-6 Besides a physical examination, an electrocardiogram may be used for diagnosis to provide clues about the type of SVT, reveal any damage to the cardiac muscle, and identify any other conduction disturbances. Physicians may also elect to use other diagnostic tools, such as an event monitor or a Holter monitor, blood work (ie, thyroid stimulating hormone levels, metabolic profile, complete blood count, cardiac enzymes), electrophysiology study, or an echocardiogram. 2,4-8,18
Can SVT be alarming?
Patients who have experienced an SVT episode will probably agree that they can be alarming and unsettling. Patient counseling that focuses on how to effectively handle SVT episodes and the possible treatments and preventive strategies can have a positive impact on patients’ overall quality of life.
Can SVT be treated on its own?
Treating SVT. For some patients, most or all of their SVT episodes may cease on their own; other patients require medical intervention. The management of SVT can be classified as short term (immediate/acute) or long term. 4.
