Supraventricular tachycardia SVT is an abnormally fast heart rhythm arising from improper extrasiztole activity in the upper part of the heart. They start from either the atria or atrioventricular node. Specific treatments depend on the type of SVT. Signs and symptoms can arise suddenly and may resolve without treatment. Stress, exercise, and emotion can all result in a normal or physiological increase in heart rate, but can also, more rarely, precipitate SVT.

Episodes can last from a few minutes to one or two days, sometimes persisting until treated. The rapid heart rate reduces the opportunity for the “pump” to fill between beats decreasing cardiac output and as a consequence blood pressure. sxtrasistole

The following symptoms are typical with a rate of — or more beats per minute:. For infants and toddlers, symptoms of heart arrhythmias such as SVT are more difficult to assess because of limited ability to communicate. Caregivers should watch for lack of interest in feeding, shallow breathing, and lethargy.

Most have a narrow QRS complexalthough, occasionally, electrical conduction abnormalities may produce a wide QRS complex that may mimic ventricular tachycardia VT. In the clinical setting, the distinction surpaventricular narrow and wide complex tachycardia supraventricular vs. In addition, ventricular tachycardia can quickly degenerate to ventricular fibrillation and death and merits different consideration. In the less common situation in which a wide-complex tachycardia may actually be supraventricular, a number of algorithms have been devised to assist supraventricuular distinguishing between them.

The following types of supraventricular tachycardias are more precisely classified by their specific site of origin. Extraskstole origin junctional tachycardia:. The main pumping extrasistolr, the ventricleis protected to a certain extent against excessively high rates arising from the supraventricular areas by a “gating mechanism” at the atrioventricular nodewhich allows only a proportion of the fast impulses to pass through to the ventricles.

Supraventricular tachycardia – Wikipedia

In Wolff-Parkinson-White syndromea “bypass tract” avoids this node and its protection and the fast rate may be directly transmitted to the ventricles. This situation has characteristic findings on ECG.


Most SVTs are unpleasant rather than life-threatening, although very fast heart rates can be problematic for those with underlying ischemic heart disease or the elderly. Episodes require treatment when they occur, but interval therapy may also be used to prevent or reduce recurrence. While some treatment modalities can be applied to all SVTs, there are specific therapies available to treat some sub-types. Effective treatment consequently requires knowledge of how and where the arrhythmia is initiated and its mode of spread.

Supraventricular tachycardia

SVTs can be classified by whether the AV node is involved in maintaining the rhythm. If so, slowing conduction through the AV node will terminate it. If not, AV nodal exrtasistole maneuvers will not work, although transient AV block is still useful spraventricular it may unmask an underlying abnormal rhythm.

Once an acute arrhythmia has been terminated, ongoing treatment may be indicated to prevent recurrence. However, those that have an isolated episode, or infrequent and minimally symptomatic episodes, usually do not warrant any treatment other than observation. In general, patients with more frequent or disabling symptoms warrant some form of prevention.

A variety of drugs including simple AV nodal blocking agents such as sypraventricular 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. Radiofrequency ablation has revolutionized the treatment of tachycardia caused by a re-entrant pathway.

This is a low-risk procedure that uses a catheter inside the heart to deliver radio frequency energy exgrasistole locate and destroy the abnormal electrical pathways. Ablation has been shown to be highly effective: Similar high rates of success are achieved with AVRT and typical atrial flutter. 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.

This therapy has further improved the treatment options for people with AVNRT and other SVTs with pathways close to the AV nodewidening the application of curative ablation to young patients with relatively mild but still troublesome symptoms who would not have accepted the risk of requiring a pacemaker.
