Is supraventricular tachycardia deadly?

Not usually. Svt should no be deadly. If it lasts for a long time(many hours or days), the heart can get tired and that is potentially dangerous.
Usually not. Svt is an arrhythmia originating in the top portions of the heart. It may be caused by an abnormal circuit within the heart's electrical system that the patient was actually born with. Heart rates can reach up to 180-200 BPM and rfe patient may fell pretty lousey with this but do not carry the same clinical implications as vt. These can usually be treated with medications or catheter ablation.

Is supraventricular tachycardia (svt) in fetus deadly?

It depends. Whether supraventricular tachycardia (svt) causes problems in a fetus depends on how often and for how long the fetus remains in svt, and on the rate of the svt (how fast). Typically, if a fetus is having problems with svt, a fetal cardiac ultrasound will detect that the heart function is declining and there may be evidence for abnormal fluid collections (so called non-immune hydrops).

A question on supraventricular tachycardia- svt. At how rate is a fast heart rate deadly?

Good question. On average, heart rates over 180 are potentially fatal. Heart rates under 160 are usually not fatal, but they can be serious. The faster the heart rate in svt, the less blood fills the heart and the less blood is pumped to the rest of the body. Read more...

What is supraventricular tachycardia?

Upper heart chambers. Fast heart beat due to mechanism arising from the upper chamber of the heart is known as supraventricular tachycardia. It could be due to electrical reentry (think of it as a short circuit) or increased automaticity (electrically hyperactive cells). It is amenable to treatment in most cases. Read more...

What causes supraventricular tachycardia?

Multipe reasons. Usually one is born with an extra 'circuit' or a propensity to have rapid firing in the upper chambers of the heart. Svt can in some cases be exacerbated by activity, stress, stimulants etc. Read more...

How is supraventricular tachycardia treated?

SVT. Depending on the origin of the svt, usually av nodal block is done, through one of following; 1. Physical maneuvers, such as valsalva maneuver. 2. Medications, such as adenosine. 3. Cardioversion. Consult a cardiologist for details. Read more...

What are the causes of supraventricular tachycardia?

Short circuit. Classic svt (supraventricular tachycardia) also known as av nodal reentrant tachycardia, is a condition in which there is an extra "wire" connecting the top and bottom parts of the heart, leading to "short circuits" and intermittent rapid heart rhythms. However, svt can also be used to describe any fast heart rhythm coming from the top part of the heart. These can be normal or abnormal rhythms. Read more...

Is supraventricular tachycardia treatable?

Yes. Eliminating the "short circuit" in your heart responsible for the tachycardia by way of a procedure called ablation (performed in the cath lab) is one permanent way of treating the svt. Medications can also be used to modify the electrical activity of the heart and control the tachycardia. Consult your cardiologist to see if which treatment option suits you best. Read more...

Compare ventricular vs supraventricular tachycardia?

Atria or ventricles. Supra ventricular tachycardia: from upper chambers of the heart, is due to irritability (increased automaticity) or a short circuit (reentry), heart is usually structurally normal. Ventricular tachycardia: from lower chambers of the heart, due to irritability, can occur in normal hearts but is more often seen in hearts with scar tissue or weak hearts and can be life threatening.
