What's supraventricular tachycardia?

---

Supraventricular tachycardia (SVT) is a general term describing any rapid heart rate originating above the ventricles, or lower chambers of the heart. SVT is an arrhythmia, or abnormal heart rhythm. Specific types of SVT include atrial fibrillation, AV nodal re-entrant tachycardia, and Wolff-Parkinson-White syndrome.  (+ info)

I have SVT ( supraventricular tachycardia) my heart starts to go about 190 suddenly?

---

My heart starts beating about 190 when it starts, and it's suddenly.
My doctor gave me flecainide as medicine for it, i have to be takin it for 5 months. My heart starts beating fast suddenly when i do a sudden movement. The last time it started when i took a really deep breath. It's weird it only happend about every month or so. I get dizzy if i keep running or doing something that makes my heart beat even faster. it starts and stops suddenly. any advise about it?
Having rhythms that are symptomatic can be dangerous. You could be driving or on a ladder or swimming when the rhythm occurs having potentially dire results.

If medications have failed you - and I presume they have if you are now on flecanide and it is not working - then there is an ablation treatment that can be employed to correct the issue.

Basically they map where the impulse that is causing this problem is coming from. They then use a laser catheter to ablate (destroy) either the (a very small) area or the pathway that is causing the trouble. They access the heart via your large blood vessel (femoral vein) between your hip and your crotch on the right side.

Regardless whether they have trialed all of the medications or not, the ablation therapy is becoming more of a front line, initial therapy. It is a one time procedure. Additional therapies are not required. You often do not require medications either. Ask you cardiologist about this matter. You are looking to speak with an electrophysiolgist (a sub-specialist within cardiology)

See the link to the Mayo Clinic as an example below.

Good luck.  (+ info)

My son has Supraventricular Tachycardia SVT, he also has benign hypotonia?

---

Hi all, my son was born 4 weeks early via emergency c-section (he is now 4 months). After 45 minutes of not finding a heartbeat using the dopla machine and ultrasound, being told that i had lost him and enduring much dispair, I felt him kick. I asked to be checked again and his heartbeat was detected and strong. At birth his apgar score was 7 and 8 (at 5 minutes) and his blood gasses were fine.
On his second day of life his heart started to beat up to 280 beats per minutes which has been diagnosed as supraventricular tachycardia (SVT). His SVT is now successfully controlled by Atenolol (hopefully he will grow out of it in one year). He also has benign low tone/hypotonia which tends to get worse when his dose of Atenolol is increased.He is reaching most of his milestones and appears to have intact intelligence. When I hold him he seems really wriggly.He is seeing a physio.
Has any one had any similar experiences? Or a baby on atenolol and did it have any drowsy effects?
Thanks J
Atenolol does have side effects such as drowsiness but does its job well. As for the SVT, he might never have an attack again, or, if he does, it can easily be treated with a catheter ablation - a 2-5 hour procedure in which a catheter (small narrow line) is directed up to the heart via a vein in the groin area. Once there, they restart the arrhythmia and ablate (destroy) a small area that is responsible for the problem.  (+ info)

Scuba diving with Supraventricular Tachycardia?

---

Almost two years ago I was diagnosed with Supraventricular Tachycardia (SVT). I've always wanted to learn how to dive. I was wondering if any has any experience with this situation or something similar? Could having this condition present a problem while diving?

Summary of Condition:
It happens at random points in time. I never know exactly when it happens. When it does happen, my heart rate begins to beat at a very rapid rate--too fast to even count. I become short of breath and light headed from lack of oxygen...i'm assuming at least. It ranges anywhere from 1 minute to 10-15 minutes.

Thoughts on the matter would be greatly appreciated!
Not recommended , sorry to write that.
Please don't put your life/health in danger.  (+ info)

Does anyone else have a baby with SVT (Supraventricular Tachycardia)?

---

We discovered that our 10 month old baby has SVT (Supraventricular Tachycardia) when she was 3 months old. Her cardiologist says that she may grow out of it around age 1 or 2. I am scared that my baby will have to have heart surgery. Has anyone else had this problem? Did your child grow out of it? Did they have surgery? How long were they on medication? How did you know when they went into SVT? How did you get them out of SVT?

Thanks.
Thank you # 1. lol. My daughter's doctors have all givin me lots of information. I asked this question to hear other people's experiences with SVT.
These are all questions you should be asking your cardiologist ... and should have been explained to you by the physician or support staff (RN's) ... I am stunned that they haven't. We educate our patient and/or family on all the questions you are asking.

Older children are more likely to have more episodes of tachycardia. They're more likely to need prolonged treatment. They also may need more diagnostic tests. It's unusual for episodes of SVT to keep a child from enjoying normal activities. Most children who have episodes of tachycardia stay well even though they may need to keep taking medicine. Your child will probably need periodic check-ups but will be able to enjoy unrestricted normal activities.

Treating SVT usually has two parts. The first is stopping a current episode; the second is preventing recurrences. The approach to preventing recurrences depends on the child's age. In some cases — especially those of infants — the child may need to enter the hospital for treatment and special studies.

Sometimes simple procedures can stop a fast heart rhythm. Gagging or putting ice on the face are examples. Your child's doctor can explain this to you in more detail. At other times intravenous medications may be needed to control or stop the tachycardia. Another way to stop SVT is to place a small catheter (a thin, flexible tube) through the nostril into the esophagus. A small amount of electricity is sent through this catheter to stop the SVT. On rare occasions doctors stop SVT by giving a small electrical shock to the chest wall. This is called electrical countershock or cardioversion. A sedative or anesthetic is given before this procedure.  (+ info)

how serious is supraventricular tachycardia?

---

So I take it you know what SVT is. It depends on the condition of the heart, patients age and any underlying medical problems. Is this your daughter? It is a treatable arrhythmia and I would have to say the seriousness is based on the cause. In a younger healthy heart it is better tolerated for a while but as you get older and have addition problems it can be serious. It does require proper investigation and treatment. Do you have the results of her holter test yet? Has she had an echocardiogram done yet?  (+ info)

are these side effects im having from metoprolol (generic form of toprol) for my supraventricular tachycardia?

---

Supraventricular tachycardia is a rapid heart beat (250bpm)
I'm 17 I weigh 130pnds and I'm at 5'' 10 tall
I'm experiencing:
Loss of appetit (hungry but can't eat but eventually I will)
Weak when walking around like I'm out of shape in 5 min
Can get tired sometimes
Get temporary tingling on finger tips

I just started taking 25mg once for everyday and began taking them yesterday.. are they normal side effects and will they pass soon? I also noticed my limbs will go tingly easily manipulated like crossing my legs. I take the beta blockers for my supraventricular tachycardia
Well I am on the same medication right now Since I also have SVT, This medicine is made to help your heart demand less oxygen therefore making it beat more efficiently. It also controls blood pressure. Therefore I would say that those symptoms are pretty typical of Metoprolol Succinate use. For me, I have also had abdominal and chest pain. (i really don't think that Beta blockers are supposed to cause that Its supposed to manage that)
But remember if you feel really feint then you should get emergency medical care.  (+ info)

Anyone have a child with SVT(Supraventricular Tachycardia)?

---

My sister's newborn has just been diagnosed with this. Can anyone tell us about their personal experience with this?
Hi im31 and was diagnosed 9 yrs ago meself. I opted to have a radialablation done. My niece however was diagnosed when she was a baby and they put her on medication. She now is about 3 and doesn't have to take meds anymore. They say it is like a short circuit just in your heart. My little one when she was born had a heart murmur but she grew out of it a few mnths later. sometimes they say ir runs in the family. All i know is if they suggest meds make sure they check the rate of the babys heart and follow through with the right time everyday. goodluck  (+ info)

supraventricular tachycardia (SVT) during pregnancy?

---

For the past 2 years I have had episodes of SVT, for the past 4 months I have been fine and have had no episodes at all, does or has anyone else had this condition, how is it monitored during pregnancy? Will I be considered high risk even though I have had no episodes for so long? BTW I'm only 6 weeks pregnant and will be having my first antenatal appointment when I'm 12 weeks along. Any other advice or stories would be much appreciated.
I had this, and it was worse during pregnancy. I was referred to a cardiologist after being hospitalized for it during my second pregnancy, (I was hospitalized after a fall and almost passed out from it, during which time it was discovered) and my cardiologist wasn't concerned about it at all because my symptoms were resolved after a period of rest. She did put me on toprol (metoprolol or lopressor) to slow my heart rate, and basically after seeing me once told me to make my next appointment for after I delivered. I felt like I was being brushed off! Basically I was only being monitored by my OB, who said it was normal for your heart rate to be faster during pregnancy. (My heart rate while I was in the hospital after the SVT was discovered was as high as 184. I know for a fact that this is way too high, even during pregnancy!) They didn't consider me high risk at all, but due to other complications that doctors were never really able to understand I did end up delivering my second daughter at 32 weeks. You need to be diligent about your care and ask your doctor specific questions about how this will affect your pregnancy. When this happened to me, I was in the middle of nursing school and didn't know then the things I know now. I didn't realize how serious it was and always felt as though the doctors were brushing me off and thought I was over reacting. They always told me that everything I was experiencing was normal, even though it wasn't, and I get the impression that a lot of doctors do this to their patients. You have to be proactive with your care. Ask how this will be monitored. Ask how it can affect the baby. Ask what you can do to keep it under control and ask about possible medications that are safe for your baby. The chances are greater that everything will be fine, but if you have any concerns at all make sure you are calling your doctor and don't let them brush you off.  (+ info)

Surgery for SVT (supraventricular tachycardia)?

---

I was just wondering if anyone has had the surgery to prevent this from happening and if they could tell me what they do to you during the surgery
SVT is usually treated with a procedure called Radiofrequency Ablation. Several thin pacing catheters are threaded up to your heart from your femoral veins. The MD will use these to "map" out the extra electrical circuit in your heart and then will "burn" out this pathway so it cannot fire inappropriately anymore.
It is minimally invasive and not uncomfortable. Most places use anesthesia that will cause you to sleep through the procedure. A few places do not, and use only local and a mild sedative. While the procedure itself is not painful, it can take more than an hour to complete, and it may be difficult to lay flat on your back without moving for that long. Ask your MD about the policy regarding anesthesia in the particular hospital you will be in.
Expect to stay overnight after the procedure.
For more detailed information about the SVT and about radiofrequency ablation, check out the Heart Rhythm Society webpage.
Good Luck :>)  (+ info)
