Talk:Supraventricular tachycardia

From Wikipedia, the free encyclopedia

I hope that this SVT page is approaching ship shape. It forms a good hub for the tachycardias in general, and I think it is within the grasp of a non-medical audience.

A number of tasks remain (feel free to add to them...):

1. I agree that a good diagram of the conduction system of the heart, with the locations for the various arrhythmias would be useful.
2. Better referencing... perhaps just the relevent pages from a good cardiology text.
3. Tidy up and expand the articles and stubs that this article references to:

• • Atrial Fibrillation is pretty well finished (previous medical collaboration of the week)
  • Atrial Flutter is well started
  • The rest need some work!

Just as an FYI, Sinus Tachycardia is not considered an SVT, at least from the ACLS perspective. It is a generally normal, if fast, heart rhythm, and is not treated per se; rather, systemic causes are treated instead. All SVTs are abnormal rhythms, with ectopic pacemakers overdrive supressing the SA node's pacemaking attempts. Sinus Tach should be noted as a non-SVT and redirected elsewhere.

Sinus tach should be considered an SVT because it is both supraventricular and a tachycardia. Unfortunately, many (but not everyone) use SVT to mean PSVT (paroxysmal SVT), which is when the heart goes from normal to about 180 in no time at all. This doesn't happen with sinus tach, which tends to be a gradual change from normal sinus rhythm. Here is how Dorland's defines it:

supraventricular t. (SVT) any regular tachycardia in which the point of stimulation is located above the bundle branches, either in the sinus node, atria, or atrioventricular junction; it may also include those arising from large reentrant circuits encompassing both atrial and ventricular sites.

But yes, mention should be made about the two definitions. Mauvila 02:08, 1 November 2007 (UTC)
