Cardiovascular disease heart I00—I52— Retrieved 30 Apr Practical Notes on Interpretation and Treatment. Archived from the original on 1 November Once an acute arrhythmia has been terminated, ongoing treatment may be indicated to prevent recurrence. In the clinical setting, the exgrasistole between narrow and wide complex tachycardia supraventricular vs. In Wolff-Parkinson-White syndromea “bypass tract” avoids this supraventircular and its protection and the fast rate may be directly transmitted to the ventricles.

Supraventricular Rhythms

Re-entry or increased cardiac muscle automaticity [3]. By using this site, you agree to the Terms of Use and Privacy Policy. This section does not cite any sources.

Atrioventricular origin junctional tachycardia:. Effective treatment consequently requires knowledge of how and where the arrhythmia is initiated and its mode of spread. This situation has characteristic findings on ECG. Supraventricular tachycardia SVT is an abnormally fast heart rhythm arising from improper electrical activity in the upper part of the heart.

Retrieved 27 September In the less common situation in which a wide-complex tachycardia may actually be supraventricular, a number of algorithms have been devised to assist in distinguishing between them. They start from either the atria or atrioventricular node. Bradycardia Sinus bradycardia Sick sinus syndrome Heart block: For infants and toddlers, symptoms of heart arrhythmias such as SVT are more difficult to assess because of limited ability to communicate.


In addition, ventricular tachycardia can quickly degenerate to ventricular fibrillation and death and merits different consideration. Children’s Hospital of Philadelphia. Caregivers should watch for lack of interest in feeding, shallow breathing, and lethargy. Unsourced material may be challenged and removed. Accelerated idioventricular rhythm Catecholaminergic polymorphic Torsades de pointes.

This is a low-risk procedure that uses a catheter inside the heart to deliver radio frequency energy to locate and destroy the abnormal electrical pathways.

A variety of drugs including simple AV nodal blocking agents such as beta-blockers and verapamilas well as anti-arrhythmics may be used, usually with good effect, although the risks of these therapies need to be weighed against potential benefits.

February Learn how and when to remove this template message. Signs and symptoms can arise suddenly and may resolve without treatment.

Supraventricular tachycardia

Medications, medical procedures, surgery [5]. Myocarditis Chagas disease Cardiomyopathy Dilated Alcoholic Hypertrophic Restrictive Loeffler endocarditis Cardiac amyloidosis Endocardial fibroelastosis Arrhythmogenic right ventricular dysplasia.

While some treatment modalities can be applied to all SVTs, there are specific therapies available to treat some sub-types. This provides the same result as radiofrequency ablation but does not carry the same risk. If it is found that the wrong tissue is being frozen, the freezing process can quickly be stopped and the tissue return to normal temperature and function in a short time.

The following types of supraventricular tachycardias are more precisely classified by their specific site of origin.


SVTs can be extrasixtole by whether the AV node is involved in maintaining the rhythm. Pacing and Clinical Electrophysiology. Please help improve this section by adding citations to reliable sources. The following symptoms are typical with a rate of — or more beats per minute:. News of the World. Anastacia was diagnosed with the disease. Radiofrequency ablation has revolutionized the treatment of tachycardia caused by a re-entrant pathway. Episodes require treatment when they occur, but interval therapy may also be used to prevent or reduce recurrence.

Endocarditis infective endocarditis Subacute bacterial endocarditis non-infective endocarditis Libman—Sacks endocarditis Nonbacterial thrombotic endocarditis. Retrieved 30 October Extrasiistole from the original on June 7, The rapid heart rate reduces the opportunity for the “pump” to fill between beats decreasing cardiac output and as suprqventricular consequence blood pressure.

Pathophysiology, Diagnosis, and Management”.

Ferri’s Clinical Advisor In general, patients with more extrwsistole or disabling symptoms warrant some form of prevention. If not, AV nodal blocking maneuvers will not work, although transient AV block is still useful as it may unmask an underlying abnormal rhythm.

Retrieved June 8, Archived from the original uspraventricular 19 February Most have a narrow QRS complexalthough, occasionally, electrical conduction abnormalities may produce a wide QRS complex that may mimic ventricular tachycardia VT.

Archived from the original on From Wikipedia, the free encyclopedia. Similar high rates of success are achieved with AVRT and typical atrial flutter.
