info on supra ventricular tacki cardia?

Answer 1

Do you mean "tachycardia"?
tachycardia (tak-i-kar'-di-a) [Greek. tachys, swift; kardia, heart]. Excessively rapid action of the heart. Paroxysmal tachycardia, a temporary but sudden marked increase in frequency of heart beats, because the conducting stimulus is originating in an abnormal focus.
Please see the webpages for more details on Supraventricular tachycardia.

Answer 2

SVT is basically when the top half of your heart beats above the normal rate (tachycardia) because the nerve cluster that connects the upper and lower parts of the heart has a short circuit. Thhere are several different sort of SVT. Try looking up 'supra ventricular nodal reentrant tachycardia' on Google. This can lead to shortness of breath, nausea, dizziness and very cold limbs as the blood is only racing around the lungs rather than the whole body. I've had this for years and it's generally harmless as long as you don't let it go on for too long each time.

Things to avoid if you have been diagnosed with this are:

Caffeine (stimulates the heart and dehydrates, both bad for SVT)

Decongestants (they open up the blood vessels all around the upper body as well as the nasal passages, so when they wear off it all constricts again rather drastically, making th eheart work too hard)

This means no Lemsip or Beechams unfortunately!

Also useful to remember is that the attacks can be controlled by several things

- try not to laugh - dunking your head, particularly the lower half of your face in a bowl/bucket of iced water! This simulates drowning in cold water, kicking off a reflex which forces the heart to head back towards a normal rythm. Breathing into a paper bag has a similar, though lesser, effect.

carotid massage - find the pulse just below the corner of your jawbone on either side and rub , pressing gently - this might slow your heart rate, hopefully easing the attack.

The Valsalver manouver - basically hold your breath and push (like you're trying to push a fart!). This is helpful for easing the discomfort and can help stop the attack.

If you're taken to hospital, chances are they'll give you either Adenosine or Verapimil. Adenosine will stop your heart, effectively rebooting it as normal. This is a rather unnerving procedure as you may feel briefly as though an elephant has decided to sit on your chest! Verapimil, I am told, has a similar, though less drastic effect. Don't have grapefruit juice with either of these...

The most important thing I've found, however, is to DRINK LOTS OF WATER (and have enough salt - but not too much). This thins the blood and keeps it moving around, putting less strain on the heart and decreasing the likelihood of an attack. And it's good for you...

Answer 3

I have supra ventricular tachycardia and recently had an AV node ablation and still take beta blockers.
It is a heart rate over 150 beats per minute. The fast beat originate above the ventricles hence the name supra ventricular.
I don't know what your baseline understanding is because your question is so vague. Are you a heart patient or what?

Answer 4

It's "tachycardia" and it means a racing heart rate. Your best human source for info would be a physician, specifically a cardiologist. The reference to wikipedia by the previous responder is also a good source for info.
